This wall scanner from UNI-T can detect metal, wood and AC cables that are embedded in the wall. The device is very easy to use. When one of the materials is detected, the scanner gives an audible signal. Based on the signal strength displayed on the screen, the exact location of the object in the wall can be determined.

The scanner is ideal for construction applications, or simply for drilling into walls, floors and ceilings to prevent short circuits or damage.
