Accurately detects buried cables in walls, floors, and ceilings without wall damage, making wiring location tasks during renovations, drilling, or installations safer and more efficient. Dual detection and safety sensing for strong and weak currents, with an effective sensing distance of up to 0.5 meters. Clearly distinguishes power lines from signal lines for clearer operation and reduced risk. Extended, flexible probe adapts to complex environments. Easily fits into narrow gaps, corners, and hardtoreach areas, enabling multiangle, obstacle detection. Noise wire transmission for a clear and stable signal. Uses noise wire technology with strong antiinterference performance to deliver clearer readings. Practical use scenarios: Home renovation or remodeling: locate electrical cables and data lines behind walls before cutting, drilling, or demolition. Installing or repositioning fixtures: verify line routes behind surfaces to avoid damaging wires or interfering with existing systems. Electrical troubleshooting and upgrades: identify cable paths when adding outlets, network points, or smarthome devices.
