The Neptune Space G.divers mask is available in 2 sizes and 4 color options (emerald, blue, white and pink) and includes an integrated balanced 2nd stage regulator and low pressure hose. The patented bellows style face skirt, molded from premium grade silicon rubber, uses a “spring profile” and large sealing surface, double size of conventional masks (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 FFM 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 strap (rubber) 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 REEF patents.
G.divers line is a new high performance and stylish OCEAN REEF family of products.

- Newly designed G.divers Exhaust system design
- New G.divers SAV/octopus port makes installation of either a Surface Air Valve accessory or octopus using adapter very easy.
- Colors available (emerald, blue, white and pink)
- 2 year warranty
- Very affordable to recreational divers
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 200-250 meters (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. The GSM G.divers communication unit is the perfect addition to any training class or guided tour and operates on the same 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.
*This Kit includes the G.divers Full Face Mask and GSM G.divers Underwater Communications Unit.
Adaptability- Face Seal - Sizes
The patented bellows-type skirt with a “spring profile” has a large sealing surface (30-45 mm, double that of a conventional mask). The spring effect is achieved by a combination of the double “S” section and the inner support ribs, resulting in a comfortable fit and ample support. This allows the mask to “float” comfortably on the face. The face seal and strap concepts are OCEAN REEF patents.
The majority of the models may be supplied with two sizes: Small/Medium and Medium/Large. In order to determine whether a diver should wear a S/M or M/L mask, OCEAN REEF has designed a Mask Measuring Kit (code 33075).
The sizing and measuring system were designed in accordance with the official measuring procedure used in the Los Alamos Scientific Laboratory Charts at the SBCCOM Mask Fit Facility-Aberdeen Proving Ground (Maryland, USA). Before purchasing a mask, use the caliper to take two simple face measurements. Using the Full Face Mask Size Recommendation Chart, it is possible to evaluate the size category into which the measurements fall.
There are three different size categories on the chart: Small/Medium, Both, and Medium/Large. If the measurements fall within the both category, then the customer should technically be able to wear either size (MEDIUM/LARGE or SMALL/MEDIUM), and in that case they should try on a mask to select the best fit. Please note that the chart boundaries fade. The fading areas represent less common face measurements. It is very likely that a mask will still fit comfortably even if measurements are located in these fading areas.
