Stud Finder Wall Scanner With 3 Modes, Live AC Detection, and Center Marking Hole | compagnien
Know what lies behind the wall before you drill with a three‑mode stud finder that reveals wood, live electrical lines, and metal pipes, then provides a centered hole mark for precise placement. It detects wood studs, joists, nails, and conduits up to 38mm deep, live AC wires up to 50mm, and copper conductors up to 40mm, with steel and copper pipes detected out to 120mm and 100mm respectively.
| Mode | Detects | Max depth |
|---|---|---|
| Wood | Studs, joists, nails, conduits | 38mm |
| Cable | Live AC wires, single‑strand copper | 50mm (AC), 40mm (copper) |
| Metal | Steel, iron, rebar, copper pipes | 120mm (steel), 100mm (copper) |
The device features a centered hole and a tri‑colour LED ring to guide drilling with clear visual cues. Green indicates a safe area with no target detected, Yellow signals you’re near the edge of a hidden object, and Red (with beep) means you’re over the center—mark the spot and proceed with confidence.
| LED colour | What it means |
|---|---|
| Green | Safe area – no target detected |
| Yellow | Approaching edge of hidden object |
| Red (with beep) | Over the centre – mark now |
A smart TFT HD colour display provides a real‑time scan snapshot, showing the selected mode, target depth, probe signal strength, distance to centre, battery level, volume, and centre confirmation at a glance. An HPC anti‑interference module helps filter out insulation noise, multi‑layer compounds, and nearby electrical fields for consistent accuracy on modern walls.
Fine‑tune performance with three sensitivity settings to suit your wall type and reduce false readings: Low for thin plasterboard, Medium for standard drywall, and High for thick concrete or masonry.
Power comes from a USB‑C rechargeable 300mAh battery, delivering up to six hours of continuous use. The unit automatically shuts down after five minutes of inactivity to preserve charge and can be powered from any USB‑C cable or power bank.
The tool is built with an ABS shockproof shell and an anti‑slip grip, designed to withstand worksite drops and long scanning sessions. This is a professional‑grade instrument intended for contractors and serious DIYers alike.
