The Ocean Reef GSM GDivers Communications System allows a great evolution of the diving activity and an outstanding improvement of the underwater instruction and education. Besides, the Ocean Reef GSM GDivers Communications System is also making the diving activity safer and more enjoyable. The new GSM Gdivers transceiver (high performance communication system) expands the diver's ability to communicate with others verbally. The ultrasonic transceiver boasts the autonomy of approximately 30 hours in receiving mode, a range of operation of over 600' (200-250 meters) in calm sea water, lightweight and sleek design. The Ocean Reef GSM GDivers Communications System is a powerful, single channel and inexpensive PTT (push to talk) underwater wireless communication unit. The unit automatically activates upon contact with the water and it uses a 9V alkaline battery with a low battery alarm which beeps every 30 seconds when the battery is low (1-hour run time remaining).
The Ocean Reef GSM GDivers Communications System is the perfect addition to any training class or guided tour and operates on the same 32.768 kHz frequency as all other Ocean Reef units and most popular wireless communication units on the market. Ocean Reef GSM GDivers Communications System uses a D-Mic, a special microphone with the housing sealed by hydrophobic membrane which is permeable to air but prevents water from passing through the electronics. The membrane's reduced thickness limits any reduction of the vocal signal. 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 Ocean Reef GSM GDivers Communications System comes with the NACS (Neptune Adjustable Communication Support) (code 33054). The patented NACS is an adjustable support arm for the Ocean Reef GSM GDivers Communications System 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. Ocean Reef GSM GDivers Communications System is depth rated for 120' (40 meters) and comes with an owner's manual.

Ocean Reef GSM GDivers Communications System Optional Upgrades:
Add a Damper - When Communicating underwater at short distance or in closed environments, it is often possible that audio distortion is caused by excessive transmission strength. The transmitters are relatively powerful and if they are used in a pool of very close to each other, distortion can be created. The audio goes "off the scale", and becomes difficult to understand. The Damper can be inserted on the antenna; it is made of a spongy material with many tiny air pockets. The combination of the two materials creates the filter needed to reduce the transmission power as needed and makes conversation intelligible again.
Add an additional NACS - System comes with the NACS (Neptune Adjustable Communication Support) (code 33054). The patented NACS is an adjustable support arm for the Ocean Reef GSM GDivers Communications System 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.
