The CL 20 Locating Device allows the detection of live and voltage-free lines. The Locating Device detects nearby electric cables and gas or water pipes located in the wall or in the ground, making it is possible to recognize short circuits and fuses. This makes the Locating Device very useful before drilling to investigate the corresponding wall or floor, to ensure that lines are not powered or in the way. The Locating Device consists of two individual units: the receiver unit and a signal generator.

In order to be useful in dark environments, both devices of the  CL 20 Locating Device are equipped with a luminous function. For the perfect lighting, three LEDs are provided on both devices. In addition to the lighting function, it is also possible to activate the backlight on the receiver unit.
