Detect studs, bolts, metal and live wiring quickly and safely with a reliable 4-in-1 wall scanner designed for accurate positioning and clear warnings. Key benefits Precision and consistency: An improved internal sensor detects changes in spatial density behind walls and pinpoints the position of bolts and beams for accurate drilling and mounting. Four detection modes: Choose the right mode for the job — Stud, Deep, Metal Scan (detects metal up to 60 mm), and AC Scan (detects live wiring up to 51 mm). Cable protection you can trust: Cable alarm detection works up to 60 mm depth and actively warns during beam scanning, depth scanning or metal scan modes so you can avoid AC cables and reduce the risk of damage or injury. Clear visual and audio guidance: Large LCD display shows directional and signal-strength information while an acoustic alarm and progressively faster beeps guide you to the exact target for fast, repeatable results. Faster, safer work: Combine visual readouts and audible cues to locate objects precisely before drilling or cutting, reducing rework and safety hazards. Features and performance Internal sensor technology for consistent detection behind walls and reliable bolt positioning. Metal scan sensitivity to 60 mm and AC live-wire detection to 51 mm, supporting a range of common installation and renovation tasks. Multi-mode operation (Stud / Deep / Metal Scan / AC Scan) for versatility across different materials and depths. Large LCD plus audible alarm for quick interpretation and confident centering on targets. Practical uses Mounting TVs, cabinets or heavy shelving: find studs and bolts and verify there are no hidden live wires in the path of your fasteners. Pre-drilling and renovation work: check for metal rebar, pipes or conduit and locate live AC wiring before cutting or demolishing walls. Electrical and maintenance tasks: confirm the presence and approximate depth of live wiring and metal elements to plan safe routing and repairs. What it solves Reduces guesswork when locating studs, bolts and hidden metal Prevents accidental contact with live AC wiring Speeds up installation and renovation tasks with clear visual and audio cues Includes the core detection modes, depth ranges and alarm functions described above for dependable, professional results in common wall-scanning applications.
