Wall fit
Why the wall surface changes the answer
Electronic stud finders sense a response associated with a change behind the surface. That means the wall is part of the instrument: its thickness, finish, moisture and construction affect what a reading can mean. Before selecting a model, name both the material and the condition of the material.
Dry, uniform drywall is the straightforward case
Many consumer electronic finders are intended for interior sheetrock or drywall. Even there, wet paint or wallpaper can interfere, and a texture or patch can look like a density change. Follow the exact model's contact and scan procedure. If a model's instructions require a clean, dry surface, do not treat a recent coat of paint as a normal test case.
Plaster and lath need a construction check
Plaster thickness can vary, and the backing can be wood lath or metal mesh. A model that may work through some lath and plaster is not thereby rated for every plaster wall. Maximum scan depth and “most walls” language should be read alongside warnings about uneven thickness and metallic reinforcement. If a maker does not describe the wall you have, keep that as an unresolved compatibility question instead of inferring support from a close product in the same family.
Tile, foil and exterior layers are not interchangeable with drywall
Tile, exterior cladding, roofing, foil-backed insulation, metallic wallpaper and metal mesh can block or distort a capacitive response. A digital finder may still show a response, but the response can be false or absent. A dedicated scanner with explicit material modes may serve a different purpose; check the exact surface and depth claims in its own manual. Do not let an “up to” number stand in for a compatibility statement.
Translate a limit into a next step
If the wall is uncertain, scan a known interior reference area, inspect the opposite side when possible, and use another independent clue such as a stud-spacing pattern or a suitable detector. Treat repeated, consistent boundaries as stronger evidence than a single flash. If the result matters for a heavy load, code-sensitive work or hidden services, ask a qualified installer rather than escalating confidence from one consumer tool.
For a more difficult-surface example, the Franklin Sensors ProSensor MAX manual specifically names lath and plaster and large tile for Mode 2, but says metal mesh may prevent plaster detection and that complex tile and exterior materials are not guaranteed. Its 2.5-inch maximum is paired with a separate 1.75-inch figure for wood studs. That is useful model-specific guidance, not a universal claim for every tiled wall or a promised depth. The MAX assessment keeps these limits separate from the manual's single-layer drywall mode.
This guide covers 101 current-reference models. Including earlier models expands the finder to 122 eligible entries; the separately reviewed FatMax 400/77-730 is withheld because the exact unit date code needed to assess recall applicability is unknown. A surface claim and a depth or signal claim apply only when the exact documented operating plan supports both. These library totals do not establish seller inventory or promise a reading through a particular wall.
A surface choice and a numeric threshold are separate requirements: keep them together only when one supported mode documents both. A drywall ceiling cannot be carried over to lath and plaster, and a conditional plaster figure does not imply the same depth in drywall. Compare a specific drywall-plus-1.5-inch scenario.
Wall-material support and indicator style must also coexist in one arrangement. Of 101 current-reference configurations, 79 document an edge indication on an eligible plan and 57 document both center and edge cues together; these signals do not establish support through plaster, tile, exterior cladding or metal mesh. Compare drywall with edge cues or keep drywall and both cue types selected together.
Including earlier models expands the comparison set, not the evidence for any one model. A surface statement and a center/edge cue remain separate unless the same model's supported plan joins them; the Milwaukee 2290's narrow ceramic-tile/marble statement does not borrow its separate drywall indicator plan. See the exact earlier-inclusive tile-and-cue scenario.
The current-reference drywall match set contains 101 configurations. The Original model 000107 and Pro both use a magnet to locate likely drywall fastener points; Pro adds plumb and horizontal bubble vials plus inch/centimeter rulers for layout. Spot adds a maker-described click and detachable Stud-Line, not a numerical depth claim. These are three distinct products, not performance tests or promises of a wall result; only the Original package explicitly excludes lath-and-plaster, while the other exact StudBuddy evidence does not establish that surface either. Read the separate 000107, Pro and Spot assessments; keep the documented drywall condition selected.
Kreg KMM1000 and KMM1000LZ are included in the drywall surface-only set. Both use two magnets to locate likely drywall-fastener points; KMM1000 adds a bubble level and centered marking notch, while KMM1000LZ adds a powered laser layout line after a point is found. Kreg's exact Q&A states a 0.150-inch maximum buried-fastener distance, so neither model reaches the finder’s 0.7-inch minimum; neither adds direct sensed edges/center, and the LZ page explicitly says it does not distinguish fasteners from live wires or conduit. Read the KMM1000 review and KMM1000LZ review as surface-only candidates. Keep dry interior drywall selected in the same finder.
Each of the five Zircon L-series models has a documented dry-interior-drywall plan. L20 SKU 75114 and L30 SKU 72187 are shallow 3/4-inch edge-only tools; L30 adds limited WireWarning. L40 SKU 72190 and L50 SKU 74941 each add a separate 1-1/2-inch edge DeepScan plan, with the L50 distinguished by its LCD. L70 OneStep SKU 74947 shows center and edges in shallow StudScan, but its separate 1-1/2-inch DeepScan is center-oriented. None of these maker instructions establishes lath/plaster or broad tile/exterior/metal-mesh support. Read the L20, L30, L40, L50 and L70 OneStep assessments. Keep dry interior drywall selected in the finder.
RYOBI ESF5002 has a documented dry-interior-drywall plan: its exact product page claims Auto Depth Scan wall-thickness identification up to 1.5 inches for wood and metal studs, while the manual describes a full-width graduated LED bar and center marker. The page figure is a comparison limit, not a promise for every finish, and the manual's typical stud width is not depth. Read the ESF5002 assessment alongside three distinct CRAFTSMAN models: CMHT77633 is edge-only, while CMHT77620 and CMHT77621 give center cues and separate limited AC warnings. The 77621's maximum is target-specific: its manual gives wood to 1 inch and metal to 1.5 inches. These makers do not establish a RYOBI lath/plaster, tile, exterior or metal-mesh plan. Keep dry interior drywall selected in the same finder.
The Calculated Industries StudMark 7310 belongs in the unfiltered drywall set: its two magnets locate likely fastener points and its two removable markers preserve them, while the manufacturer does not recommend it for plaster. Read the exact 7310 assessment; the magnetic catch is not a center/edge display or a depth reading. Keep dry interior drywall selected in the same finder.
Calculated Industries StudMark 7310 has a documented drywall fastener-point plan, but the manufacturer does not recommend plaster, and no tile/exterior plan is documented. Read its exact surface and signal limits. Open the same drywall condition in the finder.
For dry drywall and a 0.7-inch minimum, all three CRAFTSMAN models match: CMHT77633 and CMHT77620 reach 0.75 inch, and CMHT77621 has its distinct 1-inch wood and 1.5-inch metal plans. Review the edge-only 77633, the 77620 and the target-specific 77621; open the same drywall and 0.7-inch scenario. At 0.8 inches on drywall, CMHT77621 is the only one of these three that still matches, through its metal-stud plan; the 77621 wood plan reaches only one inch. Keep drywall and 0.8 inches selected. At a one-inch drywall threshold, the 77621 wood plan meets equality and its metal plan exceeds it; the 77620 and 77633 stop at 0.75 inch. Open the exact one-inch case. At 1.5 inches on drywall, the 77621 qualifies only through its metal-stud plan; it does not reach that figure for wood. Keep drywall and the 1.5-inch minimum together. A numeric-only filter does not ask which stud material is behind the wall, and none of these manufacturer ceilings predicts a reading in a particular wall.
With dry drywall and a 0.7-inch minimum, 83 reviewed configurations match, including the three CRAFTSMAN models and RYOBI ESF5002. The five Zircon L-series manuals each state a shallow 3/4-inch ceiling: L20 and L30 drop at 0.8, while L40, L50 and L70 have separate 1-1/2-inch DeepScan plans. CMHT77633 and CMHT77620 each reach 0.75 inch; CMHT77621 has separate wood and metal limits, while RYOBI ESF5002 uses a broader product-page wall-thickness ceiling. Open the same drywall and 0.7-inch result. At 0.8 inches on drywall, 66 configurations match; the 77621 remains among the CRAFTSMAN models through a metal-stud plan, while L40/L50 remain edge-only at depth, L70's deeper cue is center-oriented, and RYOBI's 1.5-inch maker-stated comparison ceiling still qualifies. Keep drywall and 0.8 inches selected. With a 1.0-inch minimum, 66 configurations match; the 77621 reaches equality for wood and exceeds it for metal, and RYOBI's broad stated wall-thickness ceiling also meets the numeric threshold. At 1.5 inches, 58 remain; the 77621's metal plan, RYOBI ESF5002 and the three deeper L-series products meet that threshold only in their documented arrangements. Open the one-inch result · Open the 1.5-inch equality result. None of these models reaches 1.6 inches. Compare the next slider boundary.
The RYOBI ESF5002 product page states a 1.5-inch Auto Depth Scan wall-thickness limit for wood and metal studs. The manual's separate 1.5-inch typical stud width is unrelated; this is a model-specific comparison ceiling, not a reading prediction. Read the ESF5002 evidence assessment and compare its separate drywall thresholds at 0.7 inches, 0.8 inches, 1.0 inch, 1.5 inches or 1.6 inches.
At a 0.8-inch minimum on drywall, RYOBI ESF5002 remains included under its 1.5-inch product-page wall-thickness ceiling. The ceiling is not a promised wall reading; the manual's typical stud-width value is a different measurement. Read the ESF5002 evidence and keep drywall and 0.8 inches selected in the same finder.
At a 1.0-inch minimum on drywall, RYOBI ESF5002 also remains included under its 1.5-inch product-page wall-thickness ceiling. The manual's separate typical stud width does not describe detection depth. Read the ESF5002 evidence and keep drywall and 1.0 inch selected in the same finder.
At equality at 1.5 inches on drywall, RYOBI ESF5002 still qualifies through the product-page wall-thickness limit for its Auto Depth Scan. That is a manufacturer-stated comparison boundary, not a guarantee for a particular wall. See the exact limit and manual distinction and keep drywall and the 1.5-inch minimum selected together.
For dry interior drywall
The DW0100 and DW0150 are separate center-only models, not an interchangeable depth profile. DW0100 is limited to 3/4 inch (19 mm) for both wood and metal studs; the DW0150 manual table allows wood to 1 inch (25 mm) and metal to 1-1/2 inches (38 mm). Both provide a separate live-AC warning, not an electrical safety clearance, and neither documents an edge mode. These are manual-stated ceilings, not predictions for a particular wall. Keep dry interior drywall selected in the finder.
For drywall, the 0.7-inch threshold returns 83 configurations; both DW0100 and DW0150 meet it on documented stud plans. DW0100's ceiling is 3/4 inch, while DW0150 has separate one-inch wood and 1.5-inch metal limits. Keep drywall and 0.7 inches selected. At 0.8 inch, 66 configurations remain: DW0100 falls below its limit; DW0150's wood and metal plans remain eligible. Preserve drywall and 0.8 inches. At 1.0 inch, the result is still 66; DW0150 meets equality on wood and exceeds it on metal, while DW0100 does not. Open the same drywall-plus-one-inch result. At 1.5 inches, 58 configurations match; only DW0150's metal-stud plan reaches equality. The questionnaire does not ask which stud material is behind the finish, and a maker maximum is not a wall-specific guarantee. Keep drywall and 1.5 inches selected.
The four Zircon configurations remain distinct tools, not one family profile: MultiScanner 540 SKU 67323 reports edges and center in StudScan and DeepScan, with 0.75-inch and 1.5-inch mode ceilings; 440 SKU 67166 and 340 SKU 67175 report edges, with their own 0.75-inch StudScan and 1.5-inch DeepScan plans; StudSensor WM5 SKU 69571 has one edge-only StudScan plan to 0.75 inch. The 340 has WireWarning but no separate AC Scan, unlike the 440 and 540; the WM5 sources document no wire-warning meter. These are source-stated limits, not expected readings through a particular wall. Keep dry interior drywall selected in the finder.
For drywall with a 0.7-inch minimum, 83 configurations match. MultiScanner 540 documents center-and-edge cues in a 0.75-inch StudScan plan; 440 and 340 provide edge cues in their shallow plans, while WM5 is edge-only. The model-specific cue types are not interchangeable, and the maker ceilings do not guarantee a wall result. Open the same drywall-plus-0.7-inch finder scenario.
At 0.8 inches on drywall, 66 configurations match. MultiScanner 540, 440 and 340 continue through separate 1.5-inch DeepScan stud plans, not their 0.75-inch shallow plans; WM5 has no deeper plan. DeepScan can respond to non-stud objects and does not promise an edge cue through every wall. Keep drywall and 0.8 inches selected.
For drywall with a 1.0-inch minimum, 66 configurations match. MultiScanner 540, 440 and 340 qualify through separate 1.5-inch DeepScan plans; their shallow StudScan plans stop at 0.75 inch, and WM5 remains below the selected threshold. Metal-target and AC ranges are not stud-depth claims. Open the same drywall-plus-one-inch result.
With drywall and a 1.5-inch minimum selected, 58 configurations remain. MultiScanner 540, 440 and 340 meet equality through DeepScan; WM5's 0.75-inch plan does not. These maker ceilings are not promises of detection or safety in a particular wall. Open the exact drywall and 1.5-inch finder result.
Drywall plus both center-and-edge indications returns 57 configurations. Among MultiScanner 540, 440, 340 and WM5, only 540 documents a direct edge-center-edge sequence; the other three are edge-only. Marking two edges and estimating a midpoint is not a center indication from the tool. Keep drywall and both cues together in the finder.
All 101 current-reference configurations have a documented dry-interior-drywall plan. The CRAFTSMAN CMHT77633 is edge-only through 3/4-inch drywall; CMHT77620 is center-only through 3/4 inch; CMHT77621 is center-only through one inch on wood and 1-1/2 inches on metal. The DW0100 stops at 3/4 inch for either stud material; the DW0150 manual separates its one-inch wood and 1-1/2-inch metal ceilings. The EXPERT D-tect18V-200-17C and D-TECT200C manuals each state 38 mm for wooden beams in drywall (about 1.496 inches), while the older GMS 120 states 1½ inches, the newer GMS120-27 states 30 mm (about 1.181 inches), and D-TECT120 states 2.36 inches in Drywall mode. Those distinct wood/stud ceilings do not borrow the models’ separate metal, wire or concrete maxima.
The two exact shop pages identify separate SuperScan models, not interchangeable variations: the W2 SKU 71684 provides wood-focused Target Control and conventional StudScan to 3/4 inch plus a separate 1-1/2-inch DeepScan; its manual cautions that deeper edge indications may not show. The Wood Stud SuperScan SKU 73241 uses Auto for shallow wood center-and-edge cues, Edge for shallow edges, and a center-only DeepScan up to 1-1/2 inches. Each model documents limited WireWarning. Keep dry interior drywall selected in the finder.
The two individually reviewed K-series shop additions add distinct choices without changing the drywall boundary: SuperScan K2 SKU 71212 has wood-filtering Target Control and conventional StudScan to 3/4 inch plus a separate 1-1/2-inch DeepScan, but no independent Metal Scan; K3 SKU 71220 documents the same stud-depth steps and adds Metal Scan for metal targets, whose distances are not stud depth. Both provide center/edge cues and limited WireWarning, and neither gains a lath/plaster plan from the drywall claims. Keep dry interior drywall selected in the finder.
Klein's magnetic MSF100 and two-unit MSF1002 use magnets to seek ferrous metal studs or fasteners behind a wall. Klein lists up to one inch per tool; the MSF1002 can provide two reference points, not extra depth. The notch and bubble vial help mark or align a point but do not become electronic edge/center cues. This is a limited drywall-only category fit, not a guaranteed reading or a plaster plan. See the exact drywall-plus-one-inch finder scenario.
C.H. Hanson adds two separate finder configurations: the standalone 3040 and the 3047 picture-hanger kit. Both use a battery-free magnet and a rotating level, but the reviewed maker pages give no numeric depth and no electronic center/edge cue or live-wire meter. The 3047 includes eight assorted hangers whose stated capacity range is 10–75 pounds, without a per-hanger map; that accessory does not extend finder depth or certify a wall installation. The pink 3046 is an exact finish variant covered in the 3040 review, not an additional matcher product. Use the exact dry-wall-only finder scenario.
The Klein models are not interchangeable: ESF050 and ESF200 each state a 3/4-inch wood-stud ceiling and auto-calibrate; ESF200 adds a separate live-AC warning, but its 1.5-inch metal and 2-inch AC figures are not stud depth. ESF100 and ESF150LL state 1.5 inches for wood and metal studs and use a trigger-operated calibration routine; both add a bubble vial, while ESF150LL alone adds selectable Class 3R cross-line lasers that do not extend stud range. None of these model pages establishes a lath/plaster or broad tile/exterior plan. Three distinct Zircon models add different capabilities: SuperScan ID SKU 74128, MultiScanner A250 SKU 72299 and MultiScanner x85 SKU 65180. ID is a one-mode color-coded scanner, A250 separates stud/metal/AC modes, and x85's separate deep wood plan has the manual's edge-at-maximum caveat. Open the exact drywall finder scenario.
These three Zircon models remain distinct from similarly named family members: SuperScan K4 SKU 71228 has wood-selective Target Control, conventional StudScan and a separate DeepScan; StudSensor 70 SKU 75118 changes from both edge/center cues at 0.75 inch to center-only High Sensitivity at 1.5 inches; and MultiScanner HD900 OneStep SKU 75116 has separate StudScan/DeepScan plans and is not the HD900c. Keep dry drywall selected in the finder.
The five Bosch entries have distinct workflows: EXPERT D-tect18V-200-17C and D-TECT200C map object edges and center in Object View, each with a 38 mm drywall wood-beam ceiling; the older GMS 120 has a 38 mm wood-stud maximum while GMS120-27 is a separate 30 mm model; D-TECT120 uses a center-cross display and a 60 mm Drywall-mode ceiling. Do not substitute separate metal, cable or concrete figures for stud depth. Open the finder with dry drywall preserved.
Those three configurations remain separate in the comparisons: StudSensor Pro LCD (SKU 75138), StudSensor i65 OneStep (SKU 73756), and the StudSensor with Picture Hanging Kit (bundle SKU 62320). Use the exact drywall finder scenario.

The current reviewed set includes the 710, 710+, M5, M10, M10S, M50, M70, M90, M150, M155, M210, MAX, T11, T13, T6, T9, X700, X990, X995, X1100, X2100, Zircon MultiScanner A200, Zircon MultiScanner A250c, MultiScanner i320 OneStep, Zircon StudScout 2-Pack, Zircon StudSensor A100, Zircon StudSensor A150, Zircon StudSensor Basic, single-unit StudScout, standard StudSensor, StudSensor Center, StudSensor e30, StudSensor e50, HD25, HD35, HD55, HD70 OneStep, Pro25, Pro35 and Pro45. Their limits and cues are not interchangeable: A200/A250c have separate stud modes, A250c adds metal and AC scans, A100 is edge-only, A150 adds a center cue, Basic is a shallower edge finder, and StudScout locates ferrous fasteners without electronic depth. The i320's deeper mode is center-only and its 3-inch metal depth is not a stud limit; e30 has no deeper mode and e50 remains edge-only. Use the finder for dry interior drywall to reach every matching configuration.
The Walabot DIY 2 and DIY 2 M lines each have four exact drywall-capable packages: DIY 2 base · DIY 2 Essential · DIY 2 Deluxe · DIY 2 Premium · DIY 2 M base · M Essential · M Deluxe · M Premium. The M product pages separately identify each package’s accessories: base device/cable, Essential rings, Deluxe case, or Premium case and rings. Walabot says the generations share a feature set as of January 2026, but that statement does not merge their identities. Both product pages name drywall and plywood, exclude lath/plaster and several difficult surfaces, and use a general object-depth ceiling rather than a numeric stud-depth rating. Open the exact dry-interior-drywall finder.
How W2 and Wood Stud SuperScan fit combined requirements
These same-condition comparisons apply to the two individually researched models on the standard dry-interior-drywall operating plan. The W2 and Wood Stud SuperScan each document shallow cue arrangements through 3/4 inch, a separate center-only DeepScan ceiling of 1-1/2 inches, and a limited WireWarning. Their ceilings are mode-specific comparisons, not promised readings or safety clearance.
With drywall and a 1.5-inch minimum selected, 58 configurations remain. The W2 and Wood Stud SuperScan qualify at equality only through separate DeepScan center plans; their 3/4-inch edge-capable plans do not reach this threshold, and a deeper maximum does not guarantee an edge cue. Read the exact mode limits or open the same-condition finder result.
At a 0.7-inch drywall minimum, 83 configurations remain. Both W2 and Wood Stud SuperScan meet this threshold through shallow center/edge-capable arrangements as well as their separate deeper plans; a low threshold still cannot guarantee a reading through every wall. Compare their assessments and keep drywall and 0.7 inches selected.
At a 0.8-inch drywall minimum, 66 configurations remain. W2 and Wood Stud SuperScan qualify through DeepScan, not their 0.75-inch shallow TC/StudScan or Auto/Edge plans. Those deeper plans are center-oriented, and the manual cautions that edge visibility can be lost. Open the same 0.8-inch drywall finder result.
At a 1.0-inch drywall minimum, 66 configurations match. W2 and Wood Stud SuperScan remain eligible through their separate 1.5-inch DeepScan center plans, not their shallow edge-capable modes; both require fresh calibration according to their instructions. Compare the W2 and Wood Stud reviews or preserve the exact condition.
Drywall plus both center-and-edge indications returns 57 configurations. W2 provides both cue types in its shallow TC, StudScan and DeepScan arrangements; Wood Stud SuperScan provides them in shallow Auto, while its Edge plan is edge-only. Neither model's 1.5-inch DeepScan center plan meets a deeper requirement for both cues. Compare the W2 and Wood Stud SuperScan, then keep drywall and both cues together.
Requiring both center-and-edge cues and a live-wire warning returns 30 configurations. W2's limited WireWarning accompanies shallow center-and-edge stud arrangements; Wood Stud SuperScan documents a limited warning in its modes, but its deeper DeepScan arrangement is center-oriented. Neither warning establishes electrical clearance. Compare the W2 and Wood Stud assessments and open the exact both-cue-and-wire finder scenario.
Requiring edge indication and a live-wire warning returns 43 configurations. W2 combines its limited warning with shallow TC, StudScan or DeepScan arrangements; Wood Stud SuperScan offers edge indication in shallow Auto and a dedicated Edge mode. The warning is not an electrical safety clearance. Compare their W2 and Wood Stud mode descriptions and keep both requirements selected.
Drywall plus a required live-wire warning returns 50 configurations. W2 documents a limited warning on supported drywall stud arrangements; Wood Stud SuperScan documents a limited warning across its modes. Either can miss wiring, so a positive alert is not a location map and an absent alert is not proof of a clear wall. Compare the W2 and Wood Stud SuperScan, then open the exact drywall-plus-wire result.
Edges plus a 0.7-inch minimum return seventy-one current-reference configurations. The W2 and Wood Stud SuperScan qualify through shallow arrangements: W2 TC/StudScan and Wood Stud Auto/Edge show an edge cue within the 3/4-inch limit. Do not transfer those edge cues to the deeper center-only DeepScan plans. Read the model-specific limits and preserve both conditions in the finder here.
Both center-and-edge cues with a 0.7-inch minimum return 49 configurations. W2's shallow StudScan and wood-focused TC plan provide both cues; Wood Stud SuperScan's Auto plan does too, while its Edge mode alone does not. Their deeper center-only modes are a separate comparison. See the W2 and Wood Stud assessments and keep both cues and 0.7 inches selected.
Drywall, both center-and-edge cues, a live-wire warning and a 0.7-inch minimum leave twenty-eight reviewed configurations. Both W2 and Wood Stud SuperScan satisfy the combination only on compatible shallow plans with their limited WireWarning; at greater depth, the maximum is center-only and edge visibility is not established. Neither alert is safety clearance. Compare the W2 and Wood Stud reviews, then open the exact four-condition finder result.
A 1.5-inch minimum plus a required live-wire warning returns 39 configurations. W2 and Wood Stud SuperScan reach equality only through DeepScan center plans paired with limited WireWarning; neither deep plan supplies both edges and center. An absent alert does not prove electrical safety. Read their W2 and Wood Stud SuperScan assessments and keep warning and depth selected together.
With earlier products included and a 1.5-inch minimum, 69 configurations match. The W2 and Wood Stud SuperScan are among the current models that reach equality through separate center-oriented DeepScan plans; adding earlier products does not extend either ceiling or turn WireWarning into an electrical-clearance test. Compare the W2 and Wood Stud assessments and open the exact earlier-inclusive 1.5-inch result.
An earlier-inclusive 0.7-inch minimum returns 101 configurations. W2 and Wood Stud SuperScan appear through supported drywall plans; each has shallow cue plans stated to 3/4 inch and a separate 1.5-inch DeepScan plan. Those capabilities remain distinct, and a maker limit is not a guaranteed reading. See the W2 and Wood Stud reviews and keep earlier models and 0.7 inches selected.
Including earlier models and requiring a live-wire warning returns 61 configurations. W2 and Wood Stud SuperScan document limited warnings on supported arrangements; neither is an electrical safety test, and both can miss wiring. Compare the W2 and Wood Stud assessments, then open the exact earlier-inclusive live-wire result.
The same earlier-inclusive live-wire answer returns 61 configurations. The current W2 and Wood Stud SuperScan document a limited WireWarning; the original, Plus and Plus X Walabot models discussed below do not document a dedicated live-wire meter. None of these tool warnings establishes a clear wall or can guarantee detection. Review the W2 and Wood Stud evidence and keep both choices in the same finder.
No StudBuddy match is supported for lath and plaster. The Original model 000107 package specifically says it is not intended for lath-and-plaster walls; the reviewed Pro and Spot sources give no plaster operating plan, so their drywall claims cannot be stretched to this construction. Read the exact 000107, Pro and Spot evidence, and keep lath and plaster selected in the same finder.
Kreg does not add a lath-and-plaster match. The KMM1000 sources establish a drywall fastener-point plan only; the KMM1000LZ Q&A gives conflicting sheetrock-mud/depth wording rather than an unambiguous lath-and-plaster procedure. Compare the exact KMM1000 surface limits and KMM1000LZ surface limits; do not infer plaster support from the magnet or laser layout feature. Keep the same lath-and-plaster condition selected in the finder.
The three CRAFTSMAN manuals do not document a lath-and-plaster operating plan, and RYOBI ESF5002 warns that variable plaster/lath density can produce inaccurate readings rather than confirming support. Read the ESF5002 surface limits, then the exact CMHT77633, CMHT77620 and CMHT77621 assessments before treating a different wall as supported. Keep lath-and-plaster selected in the same finder.
Calculated Industries explicitly does not recommend the StudMark 7310 for plaster because wall thickness varies; this magnetic fastener-point method has no supported lath-and-plaster matcher plan. Read the 7310 surface assessment, and keep the plaster condition selected in the same finder.
Seventeen of the 101 current-reference configurations have conditional lath-and-plaster plans; none of the five Zircon L-series manuals recommends that surface. The L20/L30 depth ceilings and L40/L50/L70 mode differences do not create plaster support: Zircon describes irregular plaster thickness as a limitation. Compare the individual L20, L30, L40, L50 and L70 instructions and keep the selected condition in the same lath-and-plaster finder.
For lath and plaster
Seventeen of the 101 current-reference configurations have a conditional lath-and-plaster plan. The DEWALT manuals explicitly exclude plaster, and a drywall rating does not establish compatibility with lath, variable plaster thickness or metal mesh. Keep the lath-and-plaster requirement selected in the finder.
The same 17 conditional Franklin arrangements remain the current-reference lath-and-plaster matches. MultiScanner 540 warns that irregular plaster can make StudScan difficult and metal mesh can prevent detection; Metal Scan may help locate lath fasteners but is not a stud-edge plan. The 440/340 and WM5 sources likewise do not establish a qualifying lath-and-plaster arrangement. Keep the surface requirement intact: open the lath-and-plaster finder scenario.
Seventeen of the 101 current-reference configurations have conditional lath-and-plaster plans, all documented by distinct Franklin Sensor arrangements. CRAFTSMAN CMHT77620/77621 explicitly exclude plaster, and CMHT77633 documents drywall but no lath-and-plaster operating plan. The three earlier Milwaukee 2290 packages do not join that set: the 2290 manual warns that heavy plaster and variable-density material can affect readings, but does not document a lath-and-plaster operating plan. None of the six Klein models adds documented plaster scanning; the four electronic manuals describe dry, clean wall conditions, and the MSF100 and MSF1002 mention felt pads that protect finishes without establishing plaster detection. The C.H. Hanson 3040 and 3047 pages mention plaster generally but do not establish a lath-and-plaster operating plan. The Bosch GMS 120 manual says irregular plaster makes wood-mode stud finding difficult and suggests locating lath nails in a separate metal scan; that is an indirect fastener workaround, not a depth-rated stud plan. The GMS120-27 manual specifies wood detection only in dry walls, and the D-TECT200C manual warns that inconsistent plaster/lath thickness can impair wood-substructure detection without establishing a supported plaster plan. The SuperScan K2 is not designed for lath and plaster; K3's manual says irregular plaster makes stud finding difficult in either stud mode, and its Metal Scan nail-head clue is not a stud-depth plan. The W2 and Wood Stud SuperScan likewise are not designed for lath and plaster; drywall plans do not establish plaster support. The remaining Bosch and Zircon models do not add a qualifying arrangement. These matches remain conditional, not promises. The four current Walabot DIY 2 configurations and four separate DIY 2 M base, M Essential, M Deluxe and M Premium configurations are excluded because the exact M page explicitly says not to use this scanner on lath and plaster. See the K2 limit and K3's indirect metal clue; keep the exact lath-and-plaster requirement.
The GMS 120 assessment explains the distinction: finding nails may corroborate framing, but it does not identify stud edges or make the tool a direct lath/plaster stud match. Keep the selected surface and use the lath-and-plaster finder to see the complete conditional set.
Three model reviews explain the limitation: SuperScan ID is not designed for lath/plaster, the A250 manual says thickness irregularities make studs difficult and mesh prevents detection, and the x85 warns of uneven plaster and mesh blockage. Keep the plaster condition in the finder.
The excluded Zircon examples are still distinct: M3 review · M4 review · Pro SL review · Pro LCD review · i65 review · picture-kit review · i520 review · HD900c review · K1 review. Read each model’s exact surface limits before treating a metal or wood-filter mode as plaster support.
The exact manuals matter: the M10 is named in its shared manual with a one-inch ceiling and a metal-mesh caution; the separate M10S manual gives its own 0.75–1.0-inch range and also warns about thickness and mesh. The M70, M90 and X700 each state conditional plaster use only up to their 1.5-inch limits; the M70 and X700 share a family sheet but X700 alone has model-specific green-center wording. The 710, 710+ and T11 are named in current shared instructions with 1.6-inch conditional limits; the T13 is named at 1.7 inches. The T6 is named at 1.5 inches, while its sibling T9 has a separate conditional 1.6-inch plaster statement despite a 1.5-inch general product-page maximum. The M210 and X2100 have their own qualified support, while the two-mode MAX warns metal mesh may stop detection. The i320 suggests Metal Scan as a separate way to locate wood-lath fasteners and says metal mesh blocks detection; the e30 and e50 manuals reject lath-and-plaster scanning. Those are not supported stud plans. Separate manuals state conditional up-to-1.5-inch plaster use for the M150, X990 and X995. The M5 manual does not establish a plaster plan; the M50 manual says conditional use, but a current manufacturer chart colors its plaster cell red without a visible legend, so that conflict is not counted as a supported plan. X1100 is omitted from the family plaster clause, and the M155 manual does not establish a plaster operating plan. The separate Pro25, Pro35 and Pro45 manuals also do not recommend lath and plaster. Read the exact model evidence and wall first. Compare the reviewed lath-and-plaster matches.
The current-reference set has no documented stud-finding plan for the questionnaire’s combined tile/exterior/metal-mesh group. This is a bounded library result, not a claim about every finder available. Keep the same difficult-surface option selected in the finder.
The three StudBuddy plans do not establish the combined tile/exterior surface option. The exact pages name drywall use, but the reviewed sources do not describe a tile, exterior-cladding or metal-mesh procedure. Treat those material claims as unknown rather than assuming that a larger magnet, a ruler or a layout line solves the surface issue. See the Original, Pro and Spot assessments; keep the difficult-surface choice in the same finder.
Neither Kreg model establishes the broad tile/exterior/metal-mesh stud-finding plan. The KMM1000 evidence is limited to its fastener search, and the exact KMM1000LZ page says it will not work through tile and cement board in a shower. The layout laser does not establish a surface mode. Read the KMM1000 and KMM1000LZ assessments, and preserve the same difficult-surface request in the finder.
No reviewed model expands this difficult-surface answer with a documented plan. RYOBI ESF5002's exact manual warns about foil/fiber wallpaper and plaster with metal mesh but does not establish tile, exterior or broad mesh compatibility; its assessment keeps those conditions outside its match. The CRAFTSMAN 77620/77621 manual also excludes ceramic tile and metallic surfaces, while the 77633 manual establishes no tile, exterior or mesh plan. Read the exact 77633, 77620 and 77621 surface limits; do not substitute their drywall depth figures. Keep the difficult-surface requirement selected.
No reviewed model has a documented tile/exterior answer; the exact StudMark 7310 page establishes drywall fastener finding but no tile or exterior plan. Its source-bounded assessment does not extend the drywall claim to tile. Keep the tile/exterior choice selected in the same finder.
No current-reference Zircon L-series model documents the broad tile, exterior or metal-mesh plan. Its instructions support ordinary interior drywall and list dense tile/rock or metal-covered conditions among unsuitable or unsupported surfaces; a WireWarning feature or deeper stud mode does not change wall-material support. Review the exact L20, L30, L40, L50 and L70 limits and keep the difficult-surface answer selected.
For tile, exterior, metal mesh or another difficult surface
With current-only scope, none of the 101 reviewed configurations supports the broad grouped tile/exterior/metal-mesh option. The DEWALT manuals explicitly exclude ceramic tile and metallic surfaces; neither establishes exterior or mesh scanning. See the exact current-only no-match finder scenario.
With current-only scope, none of the 101 reviewed configurations supports the broad grouped tile/exterior/metal-mesh option. MultiScanner 540/440/340 sources describe drywall plans and impose material limits; Metal Scan or AC Scan modes have different targets and do not prove a stud plan through these surfaces. WM5's edge pointer and shallow drywall ceiling do not establish tile, exterior or metal-mesh use. This is a bounded reviewed-library no-match, not a claim about every finder available. Preserve the difficult-surface choice in the finder.
With the default current-only scope, none of the 101 reviewed models documents a plan for the broad tile/exterior/metal-mesh grouping. K2 and K3 document stud plans on drywall, and K3's separate Metal Scan does not establish stud finding through tile, exterior layers or metal mesh. W2 and Wood Stud SuperScan likewise document drywall arrangements rather than the full grouped surface option. The three earlier Milwaukee 2290 package identities enter only when “Include earlier models” is selected: Milwaukee’s 2290-21 page claims detection beneath ceramic tile and marble, but does not establish exterior, metal mesh or a center/edge cue plan on tile. Keep the unresolved breadth rather than treating a material headline or another mode as proof of suitability. Review the K2's stated drywall limit and the K3 Metal Scan distinction; see the exact current-only no-match finder scenario.
The four exact DIY 2 M pages list drywall and plywood but also explicitly exclude tile, metal-backed walls, stucco, and other difficult surfaces. The M screen imagery does not qualify these packages for the broader tile/exterior/mesh option. Review the M base configuration and preserve the difficult-surface requirement in the finder; the current-library no-match result is not a claim that no maker anywhere offers such a tool.
The Bosch reviews—EXPERT D-tect18V-200-17C, GMS 120, D-TECT120, D-TECT200C and GMS120-27—retain their specific material limits rather than generalizing from scanner modes. Keep the difficult-surface requirement in the finder; the empty result is a limit of the reviewed library, not proof that no product exists elsewhere.
The four DIY 2 Essential, Deluxe and Premium listings explicitly exclude tile and metal-backed surfaces; that is why their visual object views do not qualify for this broad tile/exterior/mesh option. Keep the difficult-surface option selected. The added reviews retain their exact limits: SuperScan ID, MultiScanner A250 and MultiScanner x85 do not document the complete tile/exterior/mesh group. Keep the difficult-surface requirement in the finder; an empty result here is a limit of the reviewed library, not proof that no product exists elsewhere.
These exact reviews explain the limits: SuperScan M3 review · SuperScan M4 review · StudSensor Pro SL review · StudSensor Pro LCD review · i65 OneStep review · Picture Hanging Kit review · i520 review · HD900c review. Keep the difficult-surface requirement in the finder.
Several reviewed models document center-and-edge cues on a specified supported arrangement, including the four electronic Klein drywall models and Bosch Object View, but cue type does not establish support for the entire grouped tile, exterior, metal-mesh or other-difficult-surface choice. Klein’s exact electronic manuals describe dry indoor drywall conditions rather than this group; ESF050 and ESF200 also have only a 3/4-inch wood-stud ceiling, while ESF100 and ESF150LL state 1.5 inches without adding tile or exterior approval. The magnetic MSF100 and MSF1002 follow ferrous targets, list drywall-protective pads and provide no tile, exterior or metal-mesh plan. The C.H. Hanson 3040 and 3047 product pages likewise do not document this grouped surface plan; their general plaster mention is not a tile, exterior or mesh rating. The MAX manual permits a narrower large-tile Mode 2 case but warns about mesh, complex tile and exterior materials; that is not a plan for every group member. The M3 and M4 instructions say irregular plaster thickness makes stud finding difficult and warn metal mesh can prevent detection; neither supplies a broad tile/exterior plan. The plain Pro SL manual excludes ceramic tile, and its edge-only cues do not establish the entire grouped condition. The A200 and A250c manuals do not establish this full grouped surface plan; A250c’s metal mode is not a tile-stud mode. The StudSensor Center instructions reject ceramic tile and lath and plaster; the standard StudSensor instructions do not design for ceramic floor tile or lath and plaster. The i320 manual’s separate Metal Scan workaround finds wood-lath fasteners, not studs through mesh or tile; e30 rejects ceramic tile, and e50 rejects ceramic tile and lath and plaster. Bosch GMS 120's metal-mode lath-nail workaround is likewise not stud detection through tile or mesh; D-TECT120's conductive/metalized-surface caution does not certify the broad grouped condition. StudScout is not recommended on lath and plaster and has no documented tile/exterior plan. A100 and A150 manuals do not recommend lath and plaster, while Basic, the four HD manuals and the Pro25, Pro35 and Pro45 manuals do not document this grouped difficult-surface requirement. No current-reference model in the reviewed 101-configuration set supports the full grouped condition; this does not prove no compatible tool exists elsewhere. All four DIY 2 packages and all four distinct DIY 2 M configurations lack a supported plan for this broad group: Walabot explicitly excludes tile and metal-backed walls, and the reviewed M sources do not establish suitability for the entire exterior/mesh group. See the exact M base, M Essential, M Deluxe and M Premium assessments for their separate package identities and listed material limits. Identify the actual material and consult a purpose-specific manual before proceeding.
The M3, M4 and Pro SL do not alter this empty result: M3/M4 metal scanning is not evidence of stud-finding through mesh or tile, and Pro SL excludes ceramic tile. The i520 · HD900c · K1 likewise retain their own surface limits rather than supporting the full grouped choice.
Open the finder with the difficult-surface requirement preserved.
Kreg's explicit 0.150-inch fastener-burial maximum is below the slider's 0.7-inch lower endpoint, even when drywall is the selected surface. Thus both KMM1000 and KMM1000LZ remain excluded at drywall-plus-0.7 and drywall-plus-0.8; the LZ's laser is layout projection, not extra sensing depth. Keep drywall and 0.7 inches together or compare the same wall at 0.8 inches.
When surface and depth requirements interact
For lath and plaster with a 1.8-inch stated-depth minimum, only the reviewed MAX Mode 2 plan meets both matcher requirements; the T9's conditional plaster figure reaches 1.6 inches, while its drywall headline is 1.5 inches. MAX's manual gives a separate 1.75-inch figure for wood studs and warns that metal mesh may prevent detection.
That result selects against the overall published depth field, not a promise for a real lath-and-plaster wall or a 1.8-inch wood target. Read the MAX review before treating its 2.5-inch overall figure as relevant.
For conditional lath-and-plaster scanning at a 1.0-inch minimum, seventeen reviewed plans remain, including the M10 and M10S at their model-specific ceilings; thickness variation and metal mesh still limit the claim.
Compare the M10's named plaster provision and M10S's separate 0.75–1.0-inch range with the deeper qualified arrangements; the T6 and T9 also meet this threshold on their own conditional plans. Open the exact lath-and-1.0-inch finder result.
When the lath-and-plaster minimum rises from 1.0 to 1.1 inches, both the M10 and M10S drop out; fifteen other reviewed conditional plans remain, with the MAX still the only documented option above 1.7 inches.
The M10 and M10S manuals do not extend their one-inch plaster ceilings to a neighboring model. The T6 and T9 remain within their own conditional plaster limits. Compare the MAX's separate mode limits and keep the 1.1-inch threshold in the finder.
With lath and plaster selected and a 1.6-inch minimum, eight reviewed plans remain, including T9 through its conditional plaster plan; T6 and T9 do not share a depth ceiling.
The T9 manual's 1.6-inch plaster statement is conditional and distinct from its 1.5-inch general product-page maximum. T6 is limited to 1.5 inches; the M210 and X2100 provide examples of other supported plans at this threshold. Open the lath-and-plaster finder with 1.6 inches selected.
On drywall with a 1.5-inch minimum, forty-seven reviewed plans remain. SuperScan K2 and K3 qualify at equality through separate DeepScan stud plans; both instructions caution that edges may be difficult to see on surfaces thicker than 3/4 inch, and K3's Metal Scan does not raise stud depth. Klein ESF100 and ESF150LL reach their stated 1.5-inch stud depth at equality; the shallower ESF050 and ESF200 stop at 3/4 inch for wood studs. Bosch GMS 120 also reaches exactly 1½ inches for wood studs and D-TECT120 reaches the threshold in Drywall mode; the EXPERT D-tect18V-200-17C's 38 mm wood-beam ceiling is just below 1.5 inches and does not pass that tenth-inch setting. The other Zircon DeepScan modes and center-only StudSensor 70 remain distinct arrangements, not wall-specific guarantees.
Compare the Klein ESF050, ESF200, ESF100 and ESF150LL with Bosch GMS 120 and D-TECT120, plus SuperScan K2, SuperScan K3, SuperScan K4, StudSensor 70, HD900 OneStep, SuperScan ID, A250, x85, Pro LCD, i65 and M3. Open this exact finder scenario.
With dry interior drywall and a 1.6-inch minimum, nine reviewed finders remain, including the Bosch D-TECT120 in its 60 mm (2.36-inch) Drywall mode. GMS 120 stops at 1½ inches, and the EXPERT D-tect18V-200-17C's 38 mm wood-beam limit is below this tenth-inch step. The Klein ESF100 and ESF150LL also stop at 1.5 inches; the ESF050 and ESF200 stop earlier at 3/4 inch for wood. The T9's 1.6-inch figure applies only to conditional plaster, while Pro45's DeepScan ceiling stops at 1.5 inches.
Compare the D-TECT120 Drywall-mode plan with the GMS 120 and EXPERT 18V scanner depth limits, then read the 710, 710+, M210, MAX, T11, T13, X1100 and X2100. Open that exact drywall-and-depth scenario.
With dry interior drywall and a 0.7-inch minimum, 83 of 101 reviewed configurations match. SuperScan K2 and K3 qualify on their separate DeepScan stud plans, each stated to 1-1/2 inches; K3's Metal Scan distances are not stud depth. Klein ESF050 and ESF200 both state a 3/4-inch wood-stud limit; ESF100 and ESF150LL state 1.5 inches. The MSF100 and MSF1002 also pass this numeric-only comparison on each magnet's up-to-one-inch ferrous-target claim; the two-unit package does not extend range. C.H. Hanson 3040 and 3047 cannot meet this numeric threshold on reviewed evidence because the maker publishes no stud-depth figure for either; their drywall surface match alone does not meet a positive minimum. The eight Walabot DIY 2 and DIY 2 M configurations also have unknown stud-depth ceilings: their general four-inch object-depth statement is not a numeric stud-finding limit. The Bosch D-TECT200C clears this screen at 38 mm (about 1.496 inches) with edges, center and live-conductor cues; the GMS120-27 clears it at 30 mm (about 1.181 inches) with a center cue. Those are exact-manual wood-beam limits, not wall-specific readings, and the two configurations are distinct from the older GMS 120 and EXPERT 18V models.

At the next 0.1-inch step, drywall plus a 0.8-inch minimum returns fifty-five configurations. K2 and K3 remain through the separate DeepScan 1-1/2-inch stud plans; the TC and ordinary StudScan ceilings are only 3/4 inch, and K3's Metal Scan does not extend the stud value. Klein ESF100 and ESF150LL remain because each states 1.5 inches for studs; the MSF100 and MSF1002 also meet this comparison with their one-inch magnetic maximums. The ESF050 and ESF200 drop out at their 3/4-inch wood-stud ceiling. Both Bosch drywall wood ceilings clear this boundary: D-TECT200C is 38 mm (about 1.496 inches) and GMS120-27 is 30 mm (about 1.181 inches); their cues and upper cutoffs differ. The other models retain separate shallow and deep scan routines, and the numeric step does not erase mode-specific cue or material limits.

At a one-inch minimum on dry interior drywall, fifty-five reviewed configurations remain. SuperScan K2 and K3 qualify on separate 1-1/2-inch DeepScan stud plans; those plans are distinct from their shallower 3/4-inch TC/StudScan arrangements, and K3's Metal Scan does not extend stud depth. The exact Klein product pages and datasheets put both magnetic models at equality: MSF100 has one unit and MSF1002 supplies two. Each is rated only up to one inch for metal studs or fasteners; the second tool provides a reference point, not longer reach. This is a magnetic-target screen, not evidence that either model reads wood-stud density or guarantees a wall result. At 1.1 inches both Klein magnetic models fail the threshold, while the broader electronic models remain according to their own support plans.
K2 · K3 · Read the MSF100 assessment · Read the MSF1002 two-pack assessment. Open the exact drywall plus one-inch finder scenario.
With dry interior drywall and a 1.4-inch minimum, forty-seven configurations remain. Klein ESF100 and ESF150LL qualify at this setting on their stated 1.5-inch stud plans; ESF050 and ESF200 do not, because their wood-stud ceiling is 3/4 inch. Four Bosch candidates also qualify: GMS 120 reaches 1.5 inches, D-TECT120's Drywall mode reaches 2.36 inches, and the EXPERT D-tect18V-200-17C and D-TECT200C wood-beam maximum is 38 mm (about 1.496 inches), just above this threshold.
The metric-to-inch distinction matters here: 38 mm is not a full 1.5 inches, so those two Bosch plans fall out at the next 0.1-inch step, while the Klein ESF100/ESF150LL plans remain through equality at 1.5. Compare the Klein ESF050, ESF200, ESF100 and ESF150LL with the EXPERT 38 mm limit, D-TECT200C, GMS 120 and D-TECT120, then open the drywall finder at 1.4 inches.
At a 2.3-inch drywall minimum, two reviewed products meet the comparison: Bosch D-TECT120 in its 60 mm Drywall mode and Franklin MAX Mode 2. The D-TECT120's broader 4.75-inch concrete/metal claim is not being used; the documented drywall number is 2.36 inches.
The D-TECT120 manual-specific depth assessment and MAX mode analysis show why the threshold is target-specific. Open the exact drywall-and-depth finder scenario.
At 2.4 inches on dry drywall, only the reviewed Franklin MAX arrangement remains. Bosch D-TECT120's 60 mm ceiling is 2.36 inches, so it does not reach this next tenth-inch setting; the GMS 120 and EXPERT 18V drywall wood-stud figures are lower still.
This comparison is a numerical screen, not a promise of performance. Review the D-TECT120's separate Drywall and Concrete ranges and the MAX's wood-stud qualification, or keep drywall and a 2.4-inch threshold selected.
With drywall selected plus either edge-only or both center-and-edge indications, the two Kreg magnet models remain excluded. Their marking notch is centered on the tool body, not a sensed stud center, and the LASER-MARK line carries a located point down the wall rather than sensing boundaries. Compare the basic model with the laser-layout model; keep drywall and edges or both cues selected together.
Surface support and indicator choice must coexist
Lath-and-plaster scanning plus center-and-edge indications returns fifteen reviewed models: 710, 710+, M70, M90, M150, M210, MAX, T6, T9, T11, T13, X2100, X700, X990 and X995. The set reflects conditional surface support and does not remove each model’s plaster, depth or verification limits.
Compare the 710, 710+, M70, M90, M150, M210, MAX, T6, T9, T11, T13, X2100, X700, X990 and X995. Open the finder with both requirements.
Drywall plus both center-and-edge indications returns fifty-two configurations: four Walabot DIY 2 and four distinct DIY 2 M package identities join the prior reviewed matches on the documented app-based cue plan; K2 and K3 also document both cues on their stud arrangements. All four electronic Klein models meet this pairing: ESF050 and ESF200 state 3/4-inch wood-stud limits, while ESF100 and ESF150LL state 1.5 inches; ESF200 alone adds a dedicated live-AC warning, and ESF150LL alone adds separate cross-line lasers. Zircon K2 and K3 both show center/edge cues in TC, StudScan and DeepScan; the DeepScan edges may be difficult to see through surfaces thicker than 3/4 inch, and K3's Metal Scan is a separate mode. The magnetic MSF100 and MSF1002 do not join: their top notches and vials are marking/alignment aids, not documented sensor edges or center signals. The C.H. Hanson 3040 and 3047 are also magnetic-point finders without documented electronic edges or a center indication; the 3047's hanger kit does not change that. Walabot’s four DIY 2 and four separate DIY 2 M packages provide an app-based center-and-edge interpretation on the supported drywall plan: DIY 2 base, DIY 2 Essential, DIY 2 Deluxe, DIY 2 Premium, DIY 2 M base, M Essential, M Deluxe and M Premium. Walabot describes the feature set as shared without establishing identical hardware; a bundle case or attachment rings do not change the documented cue plan. Open the exact drywall-plus-both-cues finder result. Bosch's EXPERT D-tect18V-200-17C and D-TECT200C add Object View arrangements: their manuals describe nearest detected-object edges and a center line/cross, with 38 mm drywall wood-beam ceilings. GMS 120, GMS120-27 and D-TECT120 remain center-oriented only in the evidence reviewed here and do not satisfy both cues. Zircon's K4 and HD900 OneStep retain separate shallow/deep limits; StudSensor 70's deeper plan is center-only.

Open this exact finder scenario.
For lath and plaster with edges required, fifteen reviewed models remain. In this subset the candidate set is the same as for lath/plaster plus both center and edges: the conditional plaster-capable edge models also document a center cue, while M10 and M10S are center-only and fail the edge requirement.
For the distinct signal choices, compare the M10 and M10S center-only arrangements with the T6 and T9, whose manuals describe center and edge cues with separate conditional plaster depth statements. All plaster findings remain conditional on wall thickness, mesh and verification. Open the finder with both plaster and edge requirements preserved.
No reviewed finder plan combines the questionnaire’s broad difficult-surface grouping with a center-and-edge requirement.
Some current models document both center and edge indications on a specific supported arrangement: Klein ESF050, ESF200, ESF100 and ESF150LL do so for dry drywall, as do the EXPERT D-tect18V-200-17C, M3, M4, the StudSensor Center and the i320 in shallow StudScan. None of these cues establishes the entire grouped tile, exterior, metal-mesh or other-difficult-surface choice. M3/M4 say mesh can prevent stud detection and do not establish a tile or exterior plan; Pro SL is edge-only and excludes ceramic tile. The i320’s separate deep StudDeepScan is center-only. A200 and A250c provide both cues for supported interior stud modes, not for a metal-mesh plaster scan; Center's exact manual rejects ceramic tile and plaster; A100 has edge-only signals, A150 has both cues but its manual rejects plaster, M10 and M10S describe center without both edges, and M50's exact documentation does not assign center/edge meanings to its lights. T6/T9 center-and-edge cues do not override their manuals' tile/exterior warning. This is an empty result in the current reviewed subset, not a claim that no compatible finder exists elsewhere; consult the manual for the exact wall material. Keep both the surface and indicator requirements selected.
How the earlier-model switch changes a difficult-surface answer
With earlier models included and tile selected, the three Milwaukee 2290 package identities match only the maker’s narrow statement that the scanner detects beneath ceramic tile and marble; this does not establish exterior or metal-mesh use. Read the 2290-20 scanner assessment, 2290-21 kit assessment and 2290-23 combo assessment, and open the same earlier-inclusive tile answer. The three packages share a scanner; their different bundles do not expand its limited surface evidence.
With earlier models included, tile selected and both center-and-edge indications required, no reviewed plan matches: the 2290 tile/marble statement specifies no cue or depth arrangement, so its tile evidence cannot be combined with its separate drywall Stud-mode cues. The StudMark 7310 is also excluded here because its exact manufacturer page describes drywall fastener finding, not tile/exterior operation or electronic center-and-edge signals. Read that model's source limits and keep those exact surface and cue requirements in the finder.
With earlier models included and lath-and-plaster selected, seventeen reviewed Franklin configurations remain; the 2290 manual’s warning about heavy plaster is not a supported lath-and-plaster plan. Compare the M210’s conditional guidance and open the same earlier-inclusive lath-and-plaster scenario; verify the wall and follow its model manual.
Conditional earlier STANLEY fits on lath and plaster
Three earlier STANLEY manuals conditionally allow lath-and-plaster scanning: 77-100, 77-110 and selectable-depth 77-115; the qualification does not establish every wall assembly. Their documented stud signals are edge-led rather than direct center-and-edge output. The 77-110 text limits the allowance to construction that is not excessively thick; the 77-115 manual also cautions about unusually thick or metal-mesh walls. Read the 77-100, 77-110 and 77-115 evidence and verify the exact assembly. Keep the earlier-model and lath-and-plaster choices together.
