5 in 1 Electric Detector Wall Wood Metal Sensor Wire Stud Finder Cable Scanner.

Automatic Calibration and User-Friendly Operation
To begin, simply turn on the device, place it flat against the wall, and press the Scan button for automatic calibration. When hidden wood, metal, or AC wires are detected, the micro-sensor chip provides visual and audible alerts. The auto-calibration feature ensures ease of use and reliable detection of most materials behind walls.
LCD Display with Audible Alerts
The stud finder features a backlit LCD screen that displays detection modes, center pointing, battery status, and signal strength. A signal bar indicates the distance and direction of detected objects, while beeping sounds help pinpoint their exact location—even in low-light environments.
Live Wire Warning Indicator
For added safety, the built-in AC wire warning function is always active during Stud Scan, Deep Scan, and Metal Scan modes. It alerts you to the presence of live AC wires up to 2 inches deep, helping prevent accidents when mounting TVs, bathroom cabinets, picture frames, garage racks, and more.
