Looking for a full-face mask with communications package Ocean Reef's Neptune Space G with GSM G Communication System has your number. The Neptune Space G. divers mask is available in multiple sizes and color options and includes an integrated balanced 2nd stage regulator with a 3/8" threaded 31.5" (80cm) low pressure hose. The patented bellows style face skirt, molded from premium grade silicone rubber, uses a spring profile and large sealing double the size and spacing (30-45mm), to achieve a very comfortable fit and ample support. This spring effect is a combination of the double S section and the inner support ribs which allows the G. divers full face mask to float comfortably on the face. The head strap is directly attached to the face shield, allowing pressure to be distributed equally along the mask skirt. The six straps of the head harness hold the mask in a firm position due to their low elasticity. The tip of each rubber strap is wider, making them easier to grasp while wearing neoprene gloves. The FRB II (fast rotating buckle) allows the mask to be donned and doffed quickly. These unique face seal and strap concepts are Ocean Reefs patents.

The streamlined visor, made of transparent polycarbonate, is designed to be wider and sit closer to the face than previous full-face masks. The G. divers design maximizes the visual field, particularly the peripheral area. The visible light transfer of the visor is 92%. These factors give divers an astonishingly clear view of the underwater world.

The Extender kit is here to extend your diving possibilities. The Kit includes various accessories that integrate with communication units, but it also is compatible with sport camera mounts and can customized endlessly. The Kit comes in multiple colors, with the new NACS and earphone supports. The Space Extender is ready to extend your scuba activities to whatever you want: not only can you communicate with your buddies during the dive, thanks to the MHA2 support and the new improved NACS (communication unit not included), but it's also equipped to mount up to 3 sport cameras. Frame and components are made from durable impact resistant plastic with corrosion resistant hardware.

The underwater communication allows a great evolution of the diving activity and an outstanding improvement of the underwater instruction and education. Besides, the underwater communication is also making the diving activity safer and more enjoyable. The new GSM G. divers 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' (200-250m) in calm sea water, lightweight and sleek design. It 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 runtime remaining).

The GSM G. divers communication unit 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. GSM G. divers 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 GSM G. divers comes with the NACS (Neptune Adjustable Communication Support) (code 33054). 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. Unit is depth rated for 120' (40m). The Mask with Communications comes with owner's manual.
