Rating: Best mask on the market - Hands Down!
Reviewer: Bruce W.
Pros: This is an awesome mask! The ultimite in diving comfort. It never leaks or fogs and the field of view is excellent. The options are endless and I think eventually Im going to need the corrective lenses installed as Im getting older and my eyes are starting to go, but thats no problem with this mask. I didnt opt for the comms unit and with no regulator in my mouth I was still able to talk to my dive buddies if I got really close. Im also going to buy the add-on heads-up display at some point when the price comes down. Check it out! The air supply hose comes off easily by hand without the "quick release" option if you dont tighten it with a wrench and doesnt leak when finger tight. I had no problen adjusting the nose pieces or using them to equalize either. The look speaks for itself and when you see your vacation pictures next to your buddies Im sure youll agree. The old set up just looks so stone age next to a full face mask. Cons: Its a little pricey for the materials involved and I would have purchased more of the options if it wasnt so exspensive, but it seems to be comming down in price as more people clue into the advantages of full face masks. The surface air valve is a must and great for saving air supply when you dont need it but they need to develop a way to attach a snorkel while swimming at the surface and the valve is near the bottom so you have to keep your head quite high out of the water, again if you could attach a snorkel that wouldnt be a problem. The head straps need some kind of retainers so the loose ends are held back after tightening and not all flopping around because once adjusted you only need to get at the bottom ones to release the mask, but thats just my opinion as I like to have my equipment all sleek and streamlined without hoses and straps all dangling. Although it may look like it from my review. The pros still by far out-way the cons. Im just being picky. I hope this review helps your descision to buy a full face mask and has the best prices Ive seen anywhere on scuba gear. I live in Canada and had my order in less than a week.

Rating: Ocean Reef Neptune Full Face Scuba Dive Mask with 2nd Stage
Reviewer: Gary Shortt
I have been diving for over 40 years,and have never found a mask that I was completely happy with, until now.Although the instructions were a little intimidating,I found that there was nothing to worry about. Not having any time to try the mask out,or receive any formal training before I left for a trip to Barbados,I was a little worried about My first dive with a lot of strangers. I closed the surface air valve,rolled over the side of the dive boat,and everything about the mask performed flawlessly.That first dive and many more after were the most relaxing,and comfortable dives that I can remember.The breathing was effortless,there was no leakage,no jaw fatigue,no fogging and no dry mouth. Kudos to Ocean Reef for designing and engineering such a great product.Althoug the optional swivel joint would be an asset, the quick disconnect is a must,in My opinion. I also want to add that the Pros at were very helpfull in getting the mask to Me on time.They were very pleasant to deal with.I live in Canada and thought that ordering on line might be challanging but it wasnt.Good on You all. Thankyou!

Rating: Pure Pleasure
Reviewer: Alan Hughes
I recently used this mask in Key Largo diving to around 100 feet. This mask performed beyond my expectations. I was easy to equalize at depth and the mask never leaked or became uncomfortable or fogged. Its extremely easy to adjust and stays secure with the 6 straps. Visibility was increased and I didnt suffer any jaw fatigue by not having to bite on the reg. When at surface, you open the air value on the right hand side and breath air at the surface. Excellent design and performance. Couldnt ask for better.

Rating: An Overall Great Mask
Reviewer: Gary Twing
I mainly dive off of boats and this mask exceeded my expectations, great field of view, no fogging, no jaw fatigue, easy adjustments, and easy breathing. However, not so great a mask for beach dives. Breathing using the surface air valve while surface swimming was a little labored and got me short of breath. It also fogs up quite a bit but does clear instantly once you close the valve and breath thru the regulator. Ive ordered an Nira Male Quick Connector, sku 028055, to put on my ScubaPro G250 2nd stage so I can easily switch to it for beach dives than back to the Neptune for boat dives. Im looking forward to more boat dives!

Rating: Very Nice Mask
Reviewer: blake schoenhals
I realydont have any problems with the mask, other than that none of the paperwork really explains how to clean it. I was told that you need to wipe it down with alcohol pads after every use, because bacteria will grow and potentially cause respiratory infections even if you dont see any kind of growth in the mask it should still be done. Other than that I am very happy with the mask.

Questions and Answers for Ocean Reef Neptune Space Full Face Mask with 2nd Stage:

  • otrlife:

    how good does it seal with facial hair

    Arthur  (Certified Scuba Instructor at

    Hello, it seals great. 100% better than a conventional mask.

  • ken:

    Whats the difference between the neptune space and the space g divers ?

    Bill  (Certified Scuba Instructor at

    The G Diver is priced better and designed more for recreational divers. The Space is heavier duty and comes with a surface air valve included.

  • Chris:

    can you put the Ocean Reef GSM G.divers Wireless Diver Scuba Communication Unit on this mask at a later date?

    Bill  (Certified Scuba Instructor at

    The diver communications unit can be added later to the mask very easily. It will replace the port plug on the left size of the mask.

  • Neal:

    This model shows a threaded second stage connector on the mask, there is a quick-release adapter available right? What is the price range and where can I get one aftermarket? Thanks!

    Darrick  (Certified Scuba Instructor at

    Hello Neal, if you are looking for the quick-disconnection for this unit. If you go to: If you have any other questions or would like to place an order please feel free to give us a call at 1.800.347.2822.

  • Rajiv:

    Can you get prescription lenses fitted on this full face mask ? Also do you breathe thru your mouth or nose ? How easy is equilising ?

    Reggie  (Certified Scuba Instructor at

    With the Ocean Reef Masks you would need to get the optical lenses support and take the support into your optician for lenses. As far as breathing you can breathe through your mouth or your nose it does not make a difference both ways of breathing are very easy. As far as equalizing once you get your mask fitted it's very easy to equalize. Its just a matter of pressing the mask up against your face to block your nose, not really a drama at all.

  • Brice:

    Does this mask come with a 1st stage or does it need to be added? Also, could you add the Ocean Reef GSM G.divers Wireless Diver Scuba Communication Single Channel Unit tho this mask at a later time?

    Bill  (Certified Scuba Instructor at

    This mask includes the 2nd stage only but can be used with most first stages. Communication can easily be added later.

  • Jay:

    If this is a stupid question, please forgive me... How does a diver clear his ears wearing this mask? Thank you!

    Bob  (Certified Scuba Instructor at

    The Full Face masks have nose plugs that are easily adjusted to fit your face. You depress the levers on each side of the nose and the pads will plug the nostrils allowing for a normal Valsalva.

  • Barry:

    What are the main differences between this mask and the Space Raptor? I am I recreational diver...why would I prefer one over the other? Cant find a comparison chart for the different types of Ocean Reef masks anywhere on the web. Thnx

    Arthur  (Certified Scuba Instructor at

    The raptor is going to be a slightly more industrial/commercial mask.

The OCEAN REEF Neptune Series provides a revolutionary take on the full-face mask. They offer great visual fields, superior comfort, reliability, exceptional safety, durability, and they are easy to use! Whether you are a recreational, professional, or commercial diver, or just getting started in SCUBA, the OCEAN REEF Neptune Space series has a mask for you!

The Neptune Space mask is the first model in the Ocean Reef Professional Line of products. All Ocean Reef masks in the professional series include a built in surface air valve, dive/pre-dive switch, directional exhaust, and a limited lifetime warranty. The same great features of all Ocean Reef masks, such as the patented skirt design, balanced 2nd stage regulator, six strap head harness, and 3-D equalization system, are standard in our professional line.

The Space is our most popular mask for public safety teams and dive instructors, and is an all around top performer.

Ocean Reef’s pneumatically balanced, integrated second stage regulator provides consistent ease of breath at any tank pressure. A dive/pre dive lever helps avoid surface free flow in rough conditions. The inhalation adjustment knob allows divers to control their air delivery. The Neptune Space mask comes with a Surface Air Valve (SAV) already installed that will allow divers to breathe ambient air while at the surface.

The patented bellows style face skirt, molded from premium grade silicone rubber, uses a ‘spring profile’ and large sealing surface 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 Space 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 wide, making them easy to grasp while wearing gloves. The fast rotating buckle allows the mask to be donned and removed quickly, simply pull the quick release tabs on the bottom of the mask to remove. The unique face seal and strap concepts are Ocean Reef patents.

The streamlined visor, made of transparent polycarbonate and treated with a scratch resistant resin, is designed to be wider and sit closer to the face than previous full face masks, maximizing the visual field, especially in the peripheral area. The visible light transfer of the visor is 92%. These factors give divers and astonishingly clear view of the underwater world.

The Neptune Space 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 two one-way valves through which air is inhaled. Exhaled air is directed through a valve under the orinasal pocket and out of the mask. This limits the mixing of used air with the fresh air coming in from the regulator. On the Neptune Space the exhalation valve is directional, and can be adjusted to four positions; left, right, both or closed. This allows the diver to direct exhaled air away from the communication unit or camera gear where bubbles may interfere.

Water that may seep into the mask is quickly eliminated through exhalation or pushing the purge valve button in the second stage. Mask squeeze cannot occur with the Space mask because the pressure inside the mask is always being equalized to the pressure outside.

Ear equalization is a breeze with the Neptune Space patented 3-D equalization system. The system consists of a moveable plate and 2 eccentric blocks, which may be moved up or down and in or out to adapt to a variety of nose shapes. Included are three pairs of extensions, allowing the distance between the blocks and the nose to be modified. Simply adjust the silicone blocks to sit right under the nose, then push back on the mask to block the nostrils on descent and equalize the ears.

The Ocean Reef Space mask can be outfitted with a variety of optional accessories. An optical lens support (33299) allows for vision correction. Visor lights (OR024502) can provide hands free illumination. An Extraflex Quick Connect hose (OR024998) allows you to easily remove the mask from the 1st stage regulator set up, and a swivel (33033) can provide freer movement. Also available is a high performance 1st stage with a balance diaphragm and anti-freeze kit (YOKE 9922/DIN 9923).

Ocean Reef Neptune Space Full Face Mask

I’ve always had the impression that full faced masks where far more trouble than they were worth. Over the years I’ve had the chance to fiddle around with them in the pool as well as a few dives when I lived in the Keys, and it always seemed their advantages and novelty was easily countered by the fact that they were uncomfortable, made it difficult to clear your ears and seemed to leak constantly no matter how well they fit topside. And while they offered a fantastic field of view, having such a large airspace strapped to the front of your head seemed to offer various buoyancy challenges as well. It always seemed to me that if you were doing the type of diving that required one, it was an extremely useful piece of gear to have, but just wasn’t the best choice for a recreational diver.

My impressions were changed when I came across the Ocean Reef Neptune Space mask. At first glance I noticed how much lighter it seemed than the old masks I’d tried. Ocean Reef uses Crystal Silicone in the construction of the skirt making it soft and light weight not to mention very pliable so as to give the user a very comfortable seal around their face. Inspecting it closer I noticed that the head harness is connected to the face shield itself allowing the pressure from adjusting the mask to be spread around the entire unit in order to help maintain a tight yet comfortable seal.

Putting it on, one of the first things I noticed was the surface air valve came pre-installed in the unit I was looking at. It is placed in a very common sense spot and with a quick twist I was breathing outside air! This, in this case was important, as the mask wasn’t hooked up to an air source, being in the showroom and all. The equalization plugs were not quite set to match up with my nostrils correctly and I started to wonder if this was going to be an issue. Upon removing the mask, I was happy to see that the equalization system has a tri-dimensional adjustment allowing for an easy adapting to my nose. It took a few minutes to get used to having the little plugs blocking my nostrils but after a bit of practice I didn’t give it a second thought.

When I hooked the system up to my first stage, and took it for a couple dives, I was very pleasantly surprised to discover that the lower part of the seal on the mask slips just under your chin and helps keep the mask secured in place. No more grasping the mask and readjusting it in order to keep it from riding up on your head. The second stage performed very comfortably, delivering air effortlessly and allowed me to breath through either my nose or my mouth. The air circulates inside the mask in a manor that keeps the face shield free from fogging and with exhaust valves located on the sides of the mask; you can set them to have your bubbles go pretty much where you want them. I’m very pleased I wandered across the Neptune Space mask. I’m looking forward to adding the Quick Disconnect hose and fitting to the system to make it easier to store and care for my mask between dives.
