Stud Finder and Live Wire Detector, 3 Scan Modes

Know what is behind the wall before the drill goes in.

This detector helps you mount and drill more safely by finding what is hidden in your walls. It has three scan modes: one for wood and metal studs, one for metal, and one for live AC wires. In stud mode it detects wood and metal studs up to 38 mm deep, which covers most drywall. Metal mode locates pipes, copper, aluminum and rebar up to about 3 inches (roughly 76 mm) behind the surface, and AC mode picks up live wires at similar depths. A backlit display and a marked top notch help you pinpoint the center of what you find, even in dim rooms.

Why we picked it

• Three modes - Separate stud, metal and AC settings for targeted scanning.
• Clear feedback - Backlit screen, LED indicators and beeps confirm what it finds.
• Simple to run - Uses a 9V battery with auto shut-off and comfortable one-hand use.
