Floor Demo Ocean Reef Neptune Space G.Divers Full Face Mask

The Neptune Space G.divers mask is available in 2 sizes and 4 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 Neptune Space G.divers is the latest and most innovative design from Ocean Reef
  • Air circulation across the visor keeps the mask from fogging

  • Nitrox compatible to 40% (the recreational limits of nitrox)
  • Six strap head harness keeps the mask firmly in place on the face
  • Quick release pulls allow for easy mask removal
  • Durable, scratch resistant visor with the widest field of vision on the market
  • Masks are made in Italy and assembled in the USA

Question asked
on 4/2/2022
Hello I am in the midwest of the United States. I am inquiring if this Ocean Reef Neptune Space G.Divers Full Face Mask can be converted to a Hookah, also; can you do a install of the visor light package on the mask similar to what is seen on the Predator extended full mask! I am possibly interested in the attached for use in metal detecting beach shores. I am very thankful on your advise. Rusty Ouart 90 Prairiewood Drive South Fargo, North Dakota 58103

Hi thanks for your question, You could possibly convert it at your own risk its not made for that purpose. Not recommended by the manufacturer bas this is made to be used with a tank. Hope this helps. Have a great day! Happy Diving, Cj Diving since 1996 OnlineScuba 866-728-2293
