Know exactly what lies behind every wall before you drill with a single sweep from a 4-in-1 wall scanner that reveals metal, copper wiring, wood studs, live electrical, and copper pipes — so you mark a safe spot and drill once, not three times.
Traditional stud finders that only locate studs miss wires and pipes, leaving you to guess. This single device replaces three tools by offering four detection modes in one sweep: metal, wood stud, live wire, and copper pipe.
Edge and center indicators with a 0.1cm depth readout on the LCD show the exact middle of the stud, not just a vague area.
Built for first-timers: three buttons, an audible beep, and a signal bar that fills as you move — you can figure it out in about 30 seconds, with no instruction manual required.
Inside the scanner is a wideband sensor that reads three signal types: magnetic field for ferrous metals (rebar, nails), capacitance shift for wood studs and non-ferrous metal like copper, and AC field for live electrical. Switch the mode you need, glide the unit across the wall, and watch the LCD fill as you approach the target. When it shows Center, you’ve hit the middle with a 100% signal.
It works through drywall, plaster, brick, concrete, and tile — no tool swapping required during a project.
“I'm not handy. I bought this to hang a 65-inch TV by myself instead of paying $150 for an installer. Found both studs in under a minute, drilled twice, done. Wish I'd had it for the last house too.” — Marcus T.
Three steps to a hole you won’t regret: Step 1 — press the mode button to select metal, stud, wire, or pipe. Step 2 — hold the unit flat against the wall and slide slowly while watching the signal bar and listening for the beep. Step 3 — when the LCD shows Center with full signal, mark the wall and drill there.
