DIY Frequently Asked Questions / Stud Finder')">
Stud finders are devices that help locate wall studs, enabling you to hang pictures, mirrors and shelves securely.
Come in two basic types—electronic, which finds the stud by measuring the density of the wall, and magnetic, which detects nails and/or metal studs in the wall.
In addition to wood and metal studs, some advanced electronic stud finders will locate pipe, conduit, electrical wires and even reinforcing bar buried up to 6” in concrete.
