Five scanning modes address a range of materials and depths: wood and metal scans from 0.5 inch to 1.5 inch, up to 2.36 inch metal detection, and up to 2.0 inch live wire detection. Enhanced precision technology uses an advanced chip to stabilize quickly and pinpoint metal, wood, and AC wires hidden in walls and ceilings. This reduces guesswork, improves safety, and saves time during interior renovations. Power requires one 9V battery (not included). Smart LCD display and audible alerts provide clear guidance: the backlit LCD shows the location and depth of hidden items, and an audible beep signals proximity to an object. This supports accurate detection for mounting shelves, frames, and electronics. User-friendly operation centers on a simple one-button interface that powers the device on/off and toggles between modes. The straightforward design suits both DIY enthusiasts and professional users seeking to streamline their workflow. Use scenarios: - Locate studs and metal framing before mounting a heavy shelf, TV bracket, or cabinet. - Detect live electrical wires and other hazards to prevent drilling into wiring during renovation. - Find hidden metal conduits or studs behind walls to plan safe wiring routes for electronics installation.
