Ocean Reef's GSM G Divers transceiver expands the diver's ability to communicate with others verbally. The ultrasonic transceiver boasts the autonomy of approximately 30 hours in receiving mode and a range of operation of 200-250 meters (calm sea water).
GSM G Divers Communication Unit uses a D-Mic, a special microphone with the housing sealed by a hydrophobic membrane that prevents water from passing through to the electronics. The permeability of the membrane keeps the internal pressure equalized with the external pressure, enabling the microphone to be used at practically any depth.
Each GSM G Divers comes with the NACS (Neptune Adjustable Communication Support). The patented NACS is an adjustable support arm for the GSM G Divers and other Ocean Reef underwater communication units. It can be installed on the left side of the mask and prevents the communication unit from hanging on the mask strap. By relieving the weight of the communication unit, the NACS also allows the mask strap to slide easily through the buckle; thus, the strap can stay loose while the mask is donned and the communicator stays out of the way. The NACS can be adjusted for tilt and distance between the communication unit and the visor.
The GSM G Divers communication unit is the perfect addition to any training class or guided tour and can operate on the same frequency as all other popular wireless communication units on the market.
