Stud Finder Wall Scanner with 3 Modes Live AC Detection Center Marking Hole
Before you drill, know what lies behind the wall. This stud finder wall scanner reveals hidden hazards so you can drill with confidence. It combines three detection modes with a centered marking hole to make your next wall task precise and safe.
Three detection modes
- Wood detection: Detects wood studs, joists, nails, and conduits up to 38mm deep.
- Cable detection: Detects live AC wires and single‑strand copper, up to 50mm for AC and 40mm for copper.
- Metal detection: Detects steel, iron, rebar, and copper pipes, up to 120mm for steel and 100mm for copper.
Center marking hole and visual indicators
The tri‑colour LED ring guides your drilling with a central positioning hole for exact marks. Green means the area is safe with no target detected, Yellow indicates you’re approaching the edge of a hidden object, and Red (with beep) signals you’re over the centre—mark the spot now and drill with confidence.
Smart display and real‑time feedback
The device features a smart TFT HD colour display that shows the selected detection mode, target depth, probe signal strength, distance to centre, battery level, volume, and centre confirmation all at once for a complete scan picture.
Noise‑reduction and interference handling
An HPC anti‑interference module filters out wall insulation, multi‑layer compounds, and nearby electrical fields, delivering reliable accuracy on modern walls—not just in ideal lab conditions.
Customizable sensitivity
Fine‑tune detection with three sensitivity settings to match your wall type and reduce false positives:
- Low — best for thin plasterboard
- Medium — standard drywall
- High — thick concrete and masonry walls
Power, battery life, and charging
USB‑C rechargeable with a 300mAh battery. Enjoy up to six hours of continuous scanning. The device auto‑shuts down after five minutes of inactivity to preserve charge, and it can be charged from any USB‑C cable or power bank.
Durability and ergonomics
The ABS shockproof shell with an anti‑slip grip is built for worksite drops and impacts, and it’s comfortable to hold during extended scanning sessions. This is a professional‑grade tool designed for contractors and serious DIYers.
