Product Code: NF-820
In Stock
Price: $74.90

The NF-820 is a precision two-component device (emitter and receiver) for detecting different types and locations of cables. Ideal for detecting and tracking underground cables, as well as detecting the location of cables hidden behind walls, ceilings and floors. The device detects all types of power, coax, telephone and network cables as well as multi-core metal lines at a depth of 2 m and a distance of up to 10 km. Available with an alligator clip and headphones.
