Product Overview

Discover the most advanced full-face-mask (FFM) ever from Ocean Reef. Effortless: Completely new 2'nd stage design and engineering. This FFM breaths smooth as silk. Innovative: The 2'nd stage is integrated in the mask fully, as per Ocean Reef's philosophy, but now it can be detached quickly (level 1 tech certification required) for never-before quick servicing & swap. Rugged: Signature double coated visor is renowned for its unparalleled toughness & clearness, now combined w/tech polyurethane (PU) regulator protection & silicone deflector to absorb shocks of intense scuba diving use. Comfortable: Premium materials, redesigned orinasal pocket descending from the experience Ocean Reef built upon 100s of thousands of FFSM that they made for people around the globe.

Badass: Not Ocean Reef's words, just the natural reaction of whom gets to look at this Integrated Diving Mask (IDM) & hold it in their hands. Panoramic: Ocean Reef held the top spot for field of vision of any FFM before the Neptune III, now, they have increased it further! Practical: All the great designers in the world could come together to make the most beautiful product ever, but Ocean Reef, divers, need products that are more than beautiful, they must be practical. Neptune III is just that. Safe: Physiological benefits of nose breathing are now getting more & more attention & that is one of the great pros of a FFM, but the Neptune III combines all benefits, plus, a dive pre-dive switch, just to make sure that you have all the control you want over your 2'nd stage. Functional: This product can be used in almost any condition, Ocean Reef built it that way. For example, now the Neptune III is the first FFM that can be doffed with one hand.

Complete: Certifying this product Ocean Reef decided that they wanted to guarantee Ocean Reef divers to be able to rely on a certified set, not just a 2'nd & first stage. Neptune III can be purchased with its first stage, pressure gauge, quick connection hose, quick connection octopus & back-up conventional mask. Adaptable: Neptune III is sold w/Neptune Backpack, a tool designed by divers, for divers. Comfort. Safety. Smooth Breathing: Neptune III provides smooth breathing at any depth. It extends field of vision considerably, removes impediment in lateral movement, features a double coated visor certified as a system to new EN250 standards. Neptune III Package certification includes Ocean Reef Neptune III 3 IDM w/QD, Ocean Reef SL TX35 1'st Stage, Ocean Reef Octo w/QD and Ocean Reef Pressure Gauge. An industry first! All EN250 components designed to work together for optimal performance & safety in an EN250 certified package.

New Surface Air Valve (SAV): Design, better grasping surface & an internal valve. The mask will not fog when not connected to the cylinder & water will not drip in if forgotten open underwater. New visor geometry & new design: Neptune III offers a new visor geometry & new orinasal pocket for minimal internal volume. 13% less than Neptune Space: This orinasal pocket is the most anatomically designed on the market. New pocket + new visor combines for minimal dead air space & minimal internal volume. 24% less internal volume than competition. 20% wider field of vision. New visor offers widest field of vision than any conventional mask, any FFM & is 20% wider than Neptune Space IDM.

State-of-the-art integrated regulator is a balanced adjustable design for ease of breathing at all depths. Regulator is equipped with a dive/pre-dive switch for added protection against unwanted free flow. The regulator is Nitrox compatible up to 40% Oxygen out-of-the-box. Mask comes w/equalization plugs set in 3 sizes, screwdriver, standard 3/8" threaded low-pressure hose, padded bag to protect & carry your IDM, stickers to show off you're an Ocean Reef addicted & an owner's manual.

The Ocean Reef high performance balanced diaphragm 1st-stage regulator is designed for use w/the Neptune III FFM. The regulators use a diaphragm design to create an environmentally sealed mechanism to ensure durability & high performance even in contaminated water. The balanced diaphragm, chrome plated marine brass 1'st-stage regulator is inherently environmentally sealed. The benefit of this type of first stage design is that none of the delicate internal parts are exposed to contaminants such as salt, sand, chlorine or pool acids. These environmental contaminants can cause corrosion & mineral deposits to form on the internal mechanism deteriorating regulator performance.

With the SL35TX there is a Secondary Environmental Diaphragm Membrane that seals off the spring chamber keeping the 1'st-stage completely sealed off from the environment adding a second layer of corrosion resistance & prevention of freezing in cold water use. The regulator has an adjustable intermediate pressure to meet varying supply pressure requirements. The body of the regulator is made of marine grade brass w/a satin body finish & internally has a stainless-steel piston, Teflon seat, & stainless-steel spring. Standard yoke or DIN connection 3000 psi (200 bar) with 2 high pressure ports 7/16-20 UNF and 4 low pressure ports 3/8-24 UNF w/a superior flow rate of approx. 170 cubic feet per minute (4800 l/m) at 2030.5 psi (140 bars).

Neptune III Backpack is designed to safely carry your IDM & with thousand features. A backpack for scuba divers, designed by scuba divers. Versatility, adaptability, functionality, customization & bad ass design are the key words to this new, exciting, product from Ocean Reef. When engineering Ocean Reef's newest IDM - the Neptune III, they were confronted w/the challenge to offer more to their customers. To do that Ocean Reef asked themselves the question: What would a FFM users, like as features in a packaging for the mask? The answer was that divers don't care for a disposable box or bag. Full-Face Mask users want something that they can use to dive better. This backpack is now not only Neptune III's packaging, but a sold separately accessory as well, featuring tens of features that will challenge your creativity & satisfy your need for an intelligent solution when traveling with your Ocean Reef Full-Face Mask. The backpack has soft material padding for a comfortable wearing. Waterproof material for the external side. 2 waterproof external pockets. 6 D-rings & carabiners on the shoulder straps to hang accessories. Emergency whistle on chest clip. Different straps set ups for carrying gear. 2 secret pockets. Smart opening to have access to the mask & an elastic strap to hold it. In the mask compartment: 2 pockets for tools & little accessories & a power bank pocket. Lower compartment w/easy access & high load capacity for 1'st-stage, hoses, octo. Draining mesh on bottom. Waterproof changing mat. Ocean Reef name/luggage tag. Package also includes a downstream valve designed octopus' regulator & submersible pressure gauge.
