This wall scanner is a detector designed to search for utilities hidden in walls, including water pipes (plastic, reinforced plastic, copper or steel), heating stand pipes, steel and wooden wall frames and electric wiring. The device features four scanning modes indicated on a wide illuminated LCD. Apart from the outline, this wall scanner also identifies the center of hidden structures. The detection is accompanied by both sound and visual signals. For greater convenience, upon detecting a hidden structure, the device projects a beam that defines its exact location. Therefore, you can scan through an entire wall to see all hidden utilities and structures.
