The Mad Dogs are proud owners of the Neptune full face mask
Neptune Space full face mask
with GSM DC underwater communication
For our dive gear we have purchased the Neptune Space full face
scuba mask
with GSM DC underwater communication. We will let you know in the
next months how we learn more about this product.

Technical Characteristics for the Neptune Scuba Mask (as per manufacturer)
ADAPTABILITY The patented bellows-type skirt with a “spring profile” and
large sealing surface (30-45 mm, double that of a conventional mask) is
molded of premium grade silicone rubber. 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.
VISUAL FIELD The visor, made of transparent polycarbonate, is designed
to be wider and sit closer 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%.
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
km/hour (335 mi/hour). The visor is coated on both sides with a siloxane
resin to increase the scratching resistance. For 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 straps are 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 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.
AIR CIRCULATION The Neptune Space air circulation system is designed to
minimize fogging and reduce the amount of CO and CO 2 build-up. The
silicone oral-nasal pocket is built with two one-way valves through
which air is inhaled. Exhaled air is directed through a valve under the
oral-nasal pocket, limiting the mixing of this air (containing high
amounts of CO 2 ) with the fresh air from the regulator. The direction
of exhaled air is controlled by a four position exhaust valve. The
adjustable valve allows exhaust to flow in four 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.
DRAINING AND PRESSURE EQUALIZATION 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.
THE 3-D EQUALIZATION SYSTEM The patented Ocean REEF 3-D equalization
system is designed to allow 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. 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 extenders 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.
REGULATOR CHARACTERISTICS The pneumatically balanced second stage
provides 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 Dive/Pre-dive venturi lever reduces
free flow on the surface and provides maximum air flow while at depth.
The purge button, made by premium grade silicone rubber, has a
temperature range of operations between -40°C and 70°C (-40°F and
158°F). The purge button protection bezel is made of a high
impact-resistant double metalized/coated techno polymer.
