A stud finder that points to the center of a stud with LED arrows and a tone, rather than only to an edge. Its shallow detection depth rules out thick wall coverings.

Overview
Instead of marking both edges, this DEWALT scanner locates the center of a stud and shows direction with LED arrows plus an audible alert. A marking channel on the body lets the user mark the center directly, and AAA batteries are in the box.
The reason to buy is center detection with a marking channel, which saves measuring between edges. The limitation is the shallow depth, so plaster, tile or double layers of drywall may hide the stud.
Who it's for
Home owners and installers hanging shelves, mounts and cabinets will like the direct center mark. Anyone scanning heavy wall coverings or looking for wires and pipes should choose a tool that lists those modes.
Pros and cons
- Finds the stud center
- LED arrows and audible alert
- Marking channel on the body
- Shallow detection depth
- No wire detection listed
Performance notes
The scanner reads changes in wall density and shows which way to move the unit until the arrows meet at the center. Constant calibration means it adapts as it moves along the wall. Surface texture and wall covering thickness change how reliably it reads.
