Metal Detector Wall Scanner with Positioning Hole

Accurate Wall Scanning for Safe, Confident Drilling

Detect hidden studs, pipes and live cables before you drill. This metal detector wall scanner combines multi-material detection with a newly designed center positioning hole, so you can locate the exact drilling point directly on the wall and reduce the risk of hitting dangerous wiring or structural elements.

Designed for professional and home use, the scanner identifies metal, wood studs and AC live cables behind walls, floors and ceilings. Deep and Exact modes support accurate depth measurement up to 120 mm for metals and 100 mm for non‑ferrous metals such as copper. Dedicated ranges include wooden studs up to 38 mm (Depth mode), AC wires up to 50 mm and single‑strand copper wire up to 40 mm, helping you match the right setting to each task.

The compact ABS housing (approx. 138 × 68 × 22 mm) fits comfortably in one hand, with an intuitive LCD display that shows target depth, material type and approach to the center of the object. A three‑color indicator light provides a quick visual status: green for no target, yellow as you approach an object and red when you are close or at the center. Audible beeps support the display, with continuous alerts when the scanner reaches the center point.

The integrated HPC detection module improves anti‑interference performance and calculation speed, allowing more stable readings in environments with electrical noise. A built‑in 300 mAh rechargeable lithium battery powers the unit, and automatic shut‑off after 5 minutes of inactivity helps conserve charge. After locating the center of a stud, pipe or cable, simply use the center positioning hole to mark the exact drilling location for shelves, cabinets, wall décor, appliances and more. Supplied with a storage bag and user manual, this tool is suitable for construction and renovation professionals as well as DIY users handling home decoration, fixture mounting or maintenance work.

Why It's a Smart Choice

• Helps prevent accidental drilling into live AC cables or key structural elements
• Center positioning hole allows direct, accurate marking of drilling points
• Multi‑material detection and depth indication support a wide range of wall types and projects
