Neptune Space G.divers full face mask with GSM G.divers underwater transceiver

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.

4 color and size options available

The high performance, entry level G.divers Full Face Mask includes the following new features:

  • 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 Neptune Space air circulation system is one of a kind and is designed to eliminate fogging and reduce the amount of CO and CO2 buildup. The silicone orinasal pocket is built with 2 one-way valves through which air is inhaled. Exhaled air is directed through a valve under the orinasal pocket. This limits the mixing of used air (which contains high amounts of CO2) with the fresh air breathed from the regulator, allowing for a much safer dive and reduces the risk of breathing harmful gas buildups.

Water that may seep into the mask is easily eliminated by exhaling or pushing the “purge” button on the second stage. Mask squeeze, a common problem for conventional masks, will not occur with the Neptune Space because the pressure inside the mask is equal to the pressure outside the mask.

Equalization can also be a common issue for some divers. The Neptune Space  G.divers full face masks make clearing a breeze with the patented OCEAN REEF 3-D equalization system. The system consists of a movable plate and 2 eccentric blocks (these blocks move close to the nostrils when the upper part of the visor is pressed). Before donning the mask, the blocks may be moved up or down depending on the length of the diver’s nose. The 3-D equalization system can be adjusted for wide and narrow noses. Included are 3 pairs of extensions (3, 6 and 10mm long) allowing the distance between the blocks and the nose to be modified to accommodate any diver’s nose structure. The 3-D equalization system makes diving far more comfortable and inhibits any undesired pressure during a dive.
OCEAN REEF’s pneumatically balanced, integrated second stage regulator provides consistent ease of breath at any tank pressure. The inhalation adjustment feature allows divers to control their air delivery under any type of dive conditions.

The Neptune Space G.divers mask can also be equipped with the optional surface air valve that will allow divers to breathe ambient air while at the surface. The surface air valve is easily adjustable with large air vents and allows divers to efficiently save air while on the surface prior to a dive.
