Precision wall scanner that helps you find studs, metal, and live wires before you drill or cut Why you need it Prevent costly mistakes and safety hazards by accurately locating studs, bolts and live AC cables hidden in walls, ceilings and floors. Save time on installations and repairs with clear visual and audible guidance that quickly points you to the target. Useful for homeowners, DIYers and professionals who need fast, reliable detection across a range of building materials. Key benefits and features Accurate stud and bolt locating: Upgraded internal sensor detects changes in spatial density behind surfaces and pinpoints stud positions. Bolt edges are displayed for quick reference when mounting or fastening. 4-in-1 detection modes: Stud, Deep, Metal Scan (up to 60 mm), and AC Scan (up to 51 mm) cover common detection needs so you can switch modes for different tasks and materials. Cable protection alarm: Built-in cable alarm monitors up to 60 mm depth and warns you to avoid live AC cables during beam scanning, depth scanning or metal scan modes. Clear visual and audible guidance: Large LCD display provides directional and intensity information while the acoustic alarm/beeps guide you to the exact location for faster, more confident results. Wide material compatibility: Designed to detect metal, wooden beams and live cables behind concrete, tiles, wooden boards and similar surfaces. How it solves problems Stops accidental drilling into wires or pipes by giving advance warning of live AC cables and metal objects. Reduces rework and damaged fixtures by locating stud centers and bolt edges for secure mounting. Speeds up layout and installation tasks with a single tool that handles multiple detection needs. Practical use scenarios Mounting a TV: Use Stud mode to find studs and bolt-edge display to place mounting brackets securely, then verify no live wires are in the drilling path with AC Scan. Installing shelving or cabinets: Locate stud centers quickly and confirm bracket screw paths are free of metal or live cables to avoid damage. Renovation and electrical work: Use Deep or Metal Scan to assess behind tile, concrete or plaster during demolition or before running new wiring.
