Overview
The DEWALT DW0100 is a center-finding stud finder rated to a 3/4 inch detection depth in wood and metal, with AC and live wire detection built in and AAA batteries included in the box.
Rather than marking a stud's edge like older sensors, the DW0100 is built to locate the center point directly, using directional LED arrows and an audible alert to guide the user there. DEWALT is specific about where it will not work: concrete, mortar, block, brick, plaster, carpet, foil-faced material, metallic surfaces and ceramic tile are all listed as surfaces it cannot read.
- Center-find detection with LED arrows
- 3/4 inch depth for wood and metal
- Live wire detection built in
- Constant auto-calibration
Who it's for
Anyone mounting a TV, shelf or cabinet on standard drywall who wants a center reading and a check for live wires in the same pass. Not the tool for masonry, tiled or foil-backed walls, which the maker rules out directly.
Strengths and trade-offs
Drawn from this product's published specifications.
- Marks the stud center, not just an edge
- Live AC wire detection for safety
- Center marking channel and audible alert
- AAA batteries included
- Will not detect through concrete, brick, plaster or tile
- Not designed for foil-faced or metallic surfaces
- Cannot locate non-ferrous or plastic objects like pipes
Performance notes
Center-find technology in the DW0100 is meant to locate the middle of a stud rather than its edge, and constant auto-calibration keeps readings current as you move it across the wall. Once it locates a stud, directional LED arrows and an audible alert point toward the center, and a marking channel on the housing lets you trace that spot directly onto the wall. Its detection depth of 3/4 inch covers wood and metal, and it also flags AC and live wires for an added safety check, though it explicitly will not read concrete, brick, plaster, tile, foil-backed material or non-ferrous and plastic objects like pipes.
