The Neptune Space G.divers mask is available in 2 sizes and 4 colour options (emerald, blue, white and pink) and includes an integrated balanced 2nd stage regulator with a low pressure hose. The patented bellows style face skirt, molded from premium grade silicon 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 REEF patents.

The high performance, entry level gdivers Full Face mask includes the following new features:

• Newly designed G.divers exhaust air system.

• New G.divers SAv/octopus port which makes installation of a Surface Air valve accessory or octopus using the adapter very easy.

• Colours available (emerald, cobalt, white and pink).

• 2 year warranty.

• Very affordable to recreational divers.

 

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.

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 caliper is used to take two simple face measurements. Then using the Full Face mask Size Recommendation Chart, it is possible to evaluate the size category into which the measurements fall. 

The Neptune Space G.divers 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 build-ups.

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 G.divers  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 and 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 an optional Surface Air  valve (SAv) 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. 

 

Accessories 

 

The Neptune Space G.divers may be equipped with a surface air valve (SAV) that allows the diver to breathe ambient air while at the surface. The SAv may be easily assembled on the octopus/SAv port. Each SAV comes with 4 colored silicone rings to match the mask color. 

 

A frame specially designed for the Neptune series of masks which allows the use of standard optical lenses (not included) while diving. both lightweight and strong, the frame can be easily inserted and removed in the mask thanks to the seal side slots.

 

Made of chromium plated brass, this device allows for quick and easy connection and 

disconnection at the second stage, so the mask may be transported free of the first stage. The length of the hose is 800 mm (32 inch).

Also available in 48” length (code 33018).

 

Made of chromium plated brass, this device allows freer movement when attached to the second stage. The swivel connection can be used in conjunction with the quick connect hose.

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 or 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 make conversation intelligible again.

 

 

Since the beginning of Scuba diving, divers have wanted to talk to each other underwater. So far, the only feasible systems for audio communication have been available only to commercial divers. Unfortunately, these systems were also complicated, cumbersome, and expensive. However, OCEAN REEF has designed a communication system which is easy to use, lightweight, and within a recreational diver’s budget. 

The OCEAN REEF underwater communication system adds a whole new dimension to dive safety and enjoyment by connecting divers with each other and with partners on the surface.

It includes a diver transceiver unit (gSm G.divers), a receiving unit for diver wearing a conventional mask and regulator (m101A G.divers) and a portable surface underwater communication transceiver to be used on board or on the shore 

(m100 G.divers).

 

GSM G.divers (code OR033109) 

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.

 

The m101A G.divers is a receive-only unit operating on one channel. The m101A fits on any conventional mask strap or full face mask models. It might be held and shared by more divers thanks to the high quality speaker. The m101A’s reception is so strong that, infact, it is not always necessary to attach it to the mask strap. A diver may hold the unit or attach it to a bC, allowing other divers to listen to the transmission (dependent upon environmental conditions and distance). The unit automatically activates upon contact with the water. The m101A uses a 9v alkaline battery and has a “low battery” alarm which beeps every 30 seconds when the battery is low. The m101A unit’s total battery life is approximately 30 hours.

 

The m100 G.divers is a portable surface transceiver unit that may be worn on the operator’s belt. This is a high performance, compact, and easy to use unit. It is made to respond to the demands of communicating with divers in action without carrying expensive, complicated and heavy units. The size of the main unit is similar to a 

cellphone.

The main unit has a pTT (push to Talk) button and a headphone/microphone connector. The unit turns on when the headphone/microphone is connected to the main unit. The unit turns off automatically when the headphone/microphone 

is removed.

A 10 meter (33 feet) transducer cable connects to the main unit and is lowered into the water. The operator may control the depth of the transducer. 

It operates on one channel and uses a 9v replaceable alkaline battery with autonomy of approximately 9 hours. The range of operation is approx 200 meters (600 feet).

The unit comes with the following items:  

> 10 meter (33 feet) transducer cable

>  headphone/microphone

> Screwdriver
