About Ocean Reef M100 G Divers Portable Transceiver Surface Unit

The M100 G.divers is a portable surface transceiver unit that may be worn on the operator's belt. This is a high performance, compact, and easy to use unit. It is made to respond to the demands of communicating with divers in action without carrying expensive, complicated and heavy units. The size of the main unit is similar to a cell phone. The main unit has a PTT (Push to Talk) button and a headphone/microphone connector. The unit turns on when the headphone/microphone is connected to the main unit. The unit turns off automatically when the headphone/microphone is removed. A 33' (10 meter) transducer cable connects to the main unit and is lowered into the water. The operator may control the depth of the transducer.

It operates on one channel 32.768 kHz and uses a 9V replaceable alkaline battery(not included) with autonomy of approximately 30 hours with a low battery alarm which beeps every 30 seconds when the battery is low (1-hour runtime remaining). The range of operation is approx. 600' (200 meters). The unit comes with the following items: 33' (10 meter) transducer cable, headphone/microphone, and screwdriver.
