Product Description

NEPTUNE SPACE PREDATOR -w/ SDVL (shield display and visor light) 


The Neptune Space PREDATOR mask is constructed with parts made of Anodized Anticorodal®, a light weight and durable aluminum compound used in aeronautics for applications requiring high mechanical resistance. The front cover of the mask’s state-of-the-art integrated  regulator is made of laser-cut Anodized Anticorodal® and has a light gold finish. The adjustable knob, its internal trim screw, the laser-cut hand finished frame, and the six fast release buckles are all made of AISI 316 stainless steel. The sturdy feeling of the mask’s design allows divers to make sensitive micro adjustments to the airflow, even when using gloves. The Neptune Space Predator includes the Glacier Strap. This strap is made from a HNBR rubber compound for extreme low temperatures. The total weight of the mask is 1030 g (2.28lb) with a positive buoyancy of just 232 g (0.5lb), creating a light and comfortable fit. The Neptune Space Predator is a nitrox compatible mask up to 40%. The PREDATOR is specifically designed for professional and high performance applications and comes with a Limited Lifetime Warranty.

SDVL(Shield Display & Visor Lights)

When checking important data (depth and air pressure) while diving, a diver usually has to look at a wrist computer to do so. When a diver’s hands are occupied or when visibility is low, keeping track of one’s gauges may be difficult. With the SDVL, the depth and pressure data are comfortably displayed on the right and left sides of the Neptune Space visor. These two displays are accompanied by the Visor Lights installed in the top of the visor. The depth and pressure displays are activated the moment the diver enters the water. The visor light (made of 6 in-line LEDs) is easily activated by a switch on the right side of the mask and incorporated in the surface air valve.

The SDVL is composed of:

main unit with a removable and rechargeable battery, fitted with a tank belt handle, low pressure and high pressure sensors, and wet switch contacts.The battery may be easily unscrewed, recharged and replaced. It is protected by black anodized anticorodal housing, with an overpressure valve to prevent explosions in the case of a battery malfunction. There are two o-rings on the battery body that ensure an even seal in case of an incidental partial unscrewing. A 110/220 volt battery charger is supplied with the SDVL. A High Pressure hose to be connected to your first stage. A wire connecting the main back unit to the mask, which is provided with two waterproof multi pin connectors. A double PTT button unit to control the on/off of the visor light, the brightness of the visor light, and the on/off of the depth and pressure display LEDs (if not exceeding the preset safety limits shown later). Two LED displays for the tank pressure status and the diver depth. The LEDs work by a reference bar and 10 LEDs showing the present data. It is an analogical/comparative display that gives the diver an immediate reminder of tank consumption as well as where the diver is in correlation to a 50 meter/164 feet of water


The Neptune System is not just a full face mask. It is an aggregation of diving components: a mask with a large field of vision,  a superior and comfortable regulator, and a number of optional accessories as well as an easy to read, heads up display, a durable LEDs torch and a compact and powerful underwater communication device.

OCEAN REEF’s revolutionary full face masks are the product of intense research and valuable experience acquired in the development and production of military protection equipment. The surface-based versions of our full face mask have received international approval for use in the civil sector and have been adopted by specialized departments in numerous military and defense organizations for use in Nuclear, Biological, and Chemical (NBC) operations. From the Gulf Wars/Homeland security program to Antarctic expeditions, from military use to space exploration, from commercial to recreational activities, the Full Face Mask Project, which started in 1985, and involved over 50 different types of masks, has experienced a diverse range of conditions and applications. With the development of the Neptune Full Face masks for
underwater use, OCEAN REEF is now recognized worldwide as ������������������_������������������������������������������������THE FULL FACE MASK COMPANY, wherever you dive.

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 measurements fall.

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. 


Visual Field

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%
Italcert certification PPE-05 Rif 1332/05

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.


Air circulationor-5122.jpg
The Neptune Space air circulation system is designed to minimize fogging and r educe 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.

catalog-pro-2011hr.jpgSurface 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
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 pa
irs 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.

Regulator characteristics
The Neptune masks are
-or05-0080.jpgequipped 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
