Diver Matic is a portable signalling device, visual and acoustic, for the measuring of the water level in say a borehole. Diver matic is complete with metric cable, numbered by a 0-200 meter scale (100mm increments) and cable reel.
Power supply is by a 9 Volt battery which is included in the device. With the marked numerical cable sheath it is possible to read the depth to the water surface by means of a probe which provides a lit led and acoustic signal.
