OR033109 - Ocean Reef GSM G.divers Wireless Diver Communicaton Unit
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.
More About the Neptune Space
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
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
The Neptune Space visor is made of transparent polycarbonate. It is designed to be wider and sit
closer to the face than previous full face masks. This design maximizes the visual field, particularly
the peripheral area. The visible light transfer of the visor is 92%.
Required field of vision (effective) >40% of the natural field of vision – Space masks 71.80%.
Required field of vision (binocular) >50% of binocular natural field of vision – Space masks 80.68%

Durability and scratching resistance
The visor of the Neptune Space can resist the impact of a 6.35 mm steel ball traveling at speeds
of 540 kph (335 mph). The visor is coated on both sides with a siloxane resin to increase the
scratching and chemical resistance.
Tested by STANAG 4296 = resistance to the impact of a 325mg metal fragment with a speed of
240 m/s and Impact resistance test: 39.3 mm/254 g sphere from 1300 mm, no cracking or added
protection during transport, the Neptune Space comes with a removable protective shield (to be
removed before diving).
The head harness and FRB II
The head harness 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 (Raptor and Space Fast Rotating Buckle) allows the mask to be donned and doffed quickly. Predator and
IRON MASK use an AISI 316 stainless steel with surface electric
treatment and AISI 316 stainless steel rollers.
The Neptune Space air circulation system is designed to minimize fogging and reduce
the amount of CO and CO2 buildup.
The silicone orinasal pocket is built with two one way valves through which air is
inhaled. Exhaled air is directed through a valve under the orinasal pocket, limiting
the mixing of this air (containing high amounts of CO2) with the fresh air from the
regulator. The direction of exhaled air is controlled by a directional exhaust valve. This adjustable valve allows
exhaust to flow in four possible directions:
A - To the left
B - To the right
C - Both (direction of least resistance)
D - No exhaust
Position D, the “off” position is used when the diver is in
a “head-down” position which, due to pressure on the
second stage, causes the regulator to free flow. Placing
the exhaust valve in the off position causes pressure to
build in the mask, preventing free flow and returning
the system to an “air on demand” situation.
Surface air valve
The Neptune Space is equipped with a surface air valve that allows
the diver to breathe ambient air while at the surface. The surface
air valve is easily adjustable with large air vents.
Draining and pressure equalization Water that may seep into
the mask is easily eliminated by exhaling or pushing the
“purge” button on the 2nd 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.
The 3-D equalization system
The patented OCEAN REEF 3-D equalization system is designed to allow easy equalization during a dive. The
system consists of a movable plate and two eccentric blocks (these blocks move close to the nostrils when the
upper part of the visor is pressed). When equipped with Visor Lights (see after), use the regulator to push the
mask toward your face, creating a nasal seal. The blocks plug the diver’s nose allowing equalization.
Before donning the mask, the blocks may be moved up or down depending on the length of the diver’s nose.
They may also be adjusted to fit wide or narrow noses.
The system also includes three pairs of extenders (3,
6, 10mm long) which allow the distance between the blocks and the nose to be modified to accommodate
the diver’s face. The 3-D equalization system makes diving more comfortable and inhibits any undesired pressure during a dive.
The Neptune masks are equipped with a pneumatically balanced second stage providing a consistent ease of breath
at any tank pressure. An inhalation adjustment feature allows the diver to control air delivery under a variety of
diving conditions. The system works with 2 coaxial springs.
The Dive/Pre-dive (Venturi) lever reduces free flow on the
surface and provides maximum air flow while at depth.
The Neptune Space mask complies with CE Certification
in accordance with 89/689/EEC directives under the UNI
EN250 standard rules for underwater activities, including
low temperatures (<50°F/ <10°C).
