Questions & Answers

Shopper : Under Overview, it says "Allows diver to breathe ambient air when at the surface" but in the Q&A it says the mask doesn't come with the surface breathing valve. How does the mask handle air at the surface?darrick c : Hello, you would need the surface air valve: <a href="https://www.scuba.com/p-oedgsav/ocean-reef-g-divers-surface-air-valve" target="_blank">https://www.scuba.com/p-oedgsav/ocean-reef-g-divers-surface-air-valve.</a>
Paul M : does the mask come with the surface breathing valve?darrick c : Hello Paul, no, that item would be sold separately.
Shopper : Can the full-face mask be integrated with vision correction lens?Mario C : yes it can via the mount in combination with the lenses, links below: <a href="https://www.scuba.com/p-oedaolbk/ocean-reef-optical-lens-support-black-frame-only" target="_blank">https://www.scuba.com/p-oedaolbk/ocean-reef-optical-lens-support-black-frame-only</a> <a href="https://www.scuba.com/p-oedaol/ocean-reef-aria-optical-lens" target="_blank">https://www.scuba.com/p-oedaol/ocean-reef-aria-optical-lens</a> (negative diopters only -1 to -4... if different I imagine lenses could be made like for any frame..) Dive dive dive!
WARREN F : Does this full mask come with a communication system or would that need to be purchased separately?darrick c : Hello Warren, no this mask does not come with the comms. That you would have to order as a add-on with this mask.TIM C : You will have to purchase that separately.
Shopper : I attempted scuba diving once but was unable to make it past the pool practice due to panicking from being unable to breathe through my nose as well as my mouth. This looks like a solution to my problem, but would it be a waste of money to buy this mask and only use it with rented gear from resorts we visit on vacation and would the mask be compatible with the standard gear provided?Shopper : Hello Mary, yes this would connect to any 1st stage regulator set-up. Any dive shop will be able to attach this unit to the gear you are renting. This unit does take a special class above the standard open water class. So I would contact your local dive center and see if they also teach this.

Great

Great mask. With the 2nd stage in the mask and buying the surface air vent this mask is awsome.

Best customer service experience ever

My girlfriend and I both have these mask and we love them. Never fog up and very easy to use. Also, Ocean Reef had a recall on something on these mask in 2018. They reached out to us and said we would like us to send them in so they could fix the recall. I told them we were leaving on a dive trip in a few weeks and we will send them in after the trip. They were nice enough to actually send us 2 new mask within a couple days. There customer service was absolutely fantastic. We will definitely be buying from them in the future.

Great mask

I really like the mask. The additional SAV add-on and quick disconnect kit are an absolute necessity in my opinion. Sizing: I am 6' and slender. I wear a size 7 hat size and I figured the S/M size would fit me. When I got the S/M if fit my 9yr old son perfectly but not even close for me. I had to return it for a M/L size.

Didn't like

Had to add weights to compensate for added air volume, breathing caused inside of mask to be too warm, my mouth became too dry because I couldn't intake sea water to wet my whistle. Difficult to transport when traveling by air. Other than that it is OK.

needs work

The full-face mask is a good start but needs to be improved. I found that I consumed more air with this mask than with regular masks. However, talking with my honey is GREAT!

Great mask, but....

I've recently dove with one of these masks because I seriously wanted to buy one. My instructor, a commercial diver who uses one for work, ran me through a host of exercises with it including remove-don-and-clear, bailouts, dump-and-dive, buddy-gear-swap, flood-and-clear. The mask is awesome for anti-fog, sealing, view and most aspects. The biggest cons were regulator somewhat free flows when looking downward which consumes a lot of air if not careful, the ambient air valve is too low you really use when floating on the water, and the quick connect air hose can easily come unplugged if it catches on something (like it did on my BCD strap during a dump-and-dive drill. For safety, you will always need to carry a back-up mask and have an actual octo or pony bottle instead of the spare octo on the BC inflator. This is a definite drill-until-its-instinct kind of product if you want to use it safely. If you struggle with removing your mask and regulator under water, doning and clearing it again then this is not the mask for you. Those tasks do not get easier.

Ocean Reef swivel/quick disconnect and hose

while i dont currently have a full opinion of the ocean reef neptune space g.divers full face maskim still using a far greater amount of air as compared to a regular regulator and face mask, i very happy with the savings that buying "demo" provided. i noticed no wear on the masks and all of the extras came with the masks. (lph, warranty, carrying bag, etc.)

Amazing mask

I love this mask, words can't even begin to describe how great it is. Diving with a full face mask is just amazing compared to a normal mask and rig setup. I love how well this mask fits, even with my facial hair it seals really well. And the glasses attachment works fantastic with the mask. If your looking for a full face mask thats not to expensive yet is really good quality I would definitely go Ocean Reef.

Best Purchase I ever made

I debated for a long time on buying the FFM due to the price and additional addons needed. I added the surface air valve and swivel quick disconnect. And attached to my aqua lung 1st stage. I've only used it on a couple of dives so far and I doubt I will ever go back to using a conventional regulator. It don't flood, it don't fog, and the visibility is better then any conventional mask. Clearing the ears is very easy once it is set up correctly which took some time adjusting it and practicing donning and doffing the FFM. You breather either through your nose or mouth without any issues. Clears very easily during the training for removing and donning underwater. Another good feature I discovered which is not widely talked about is while at the surface in rough water it performs awesomely if you open the surface valve, by just tilting my head to the left in rough water any water that does enter the mask just goes to the chin area and as soon as i breath out normally the water evacuates the mask never reaching the mouth or nose area and I don't need to carry around a snorkel to use while waiting on the boat.

Love it

I love this FFM. In fact I dont think I'll go back to a regulator anytime soon. Very solid performing whether on ice dives, or wrecks. Get the surface air valve and disconnect though. Really is a awesome set up worth every cent. No more spit! Never fogs. Great field of vision, and you can breath through your nose.

This mask does what it says it does, I used this mask in saba and it performed like a charm. The only thing I wish it was a little lighter. Quick and easy to put on once you get used to it.

Superb!

I've now completed my fourth dive with my new Neptune FFM. It's PHENOMENAL - on a boat dive. It fits comfortably and securely, even with a beard (everyone on the boat expected it to leak like a sieve with my beard - it didn't at all). It's incredibly comfortable, and does NOT fog. Easy to clear (I flooded it intentionally) as well, though you have to hold your breath a bit. You MUST spend a decent amount of time setting up the nose plugs BEFORE your first dive. If you do that, it's super easy to clear your ears. I am using it with my existing Zeagle primary, and only add-on I bought was the SAV (surface air valve) and the quick disconnect fittings. One issue I had though - on the surface, the SAV is on the bottom of the mask, and as such makes a long surface swim a bit of a pain, as you either have to hold your head high, or swim exclusively on your back. If you're considering it - do it!

Great product for a good price

I have used my ffm in pool dives and several ocean dives. The product is great, nice fit to my face, great comfort with the silicone seal against my skin/face. The only small negative is that it need to be adjusted with weight to be more neutral in water, i found out that my mask in salt water neded about 350-400 grams of led weights inside the mask. If i did not use the weights, i would be pretty tired in my neck after 20min of diving due to it's boyancy.

Awesome FFM, Highly recommended

I have used mask type and another and found the OCean Reef to be an excellent mask, no problems at all, Awesome Vis, No Fogging and no leaking. Have had a blast using it, now looking at buying my own FFM. I would highly reccomend this mask, but as a diving Instructor would also highly recommend training for its use prior to diving. You MUST practice donning and removing the mask while underwater prior to diving and always carry a spare mask in your pocket for use with your Octo if ever you are required to bail out of the FFM (Which is very rare).

Great mask

This is a great mask that offers a whole new way to dive. I wasn't going to write a review but after seeing such a negative review from someone I had to because I wouldn't want anyone to miss out on something like this if they were thinking about it. It is just like breathing on land and the range of visibility is far better than a conventional mask. As far as the ignorant statement from a negative review I read you do not have to use their 1st stage for the mask. It does state that you have to use it in their manual but I called the rep for Ocean Reef in California and they said you may use it with any 1st stage of your choice, and that they themselves use other 1st stages with this mask while diving with them. As far as the add ons are concerned they are "add ons"; you do not have to purchase any of them and the mask is ready to dive with as is. I do however recommend the surface air value as it helps you conserve air while on the surface. The octopus adapter is not necessary and it takes the place of the surface air value. If you choose that as an add on instead it allows you to breathe off of your oct if your primary fails without removing the mask and it is priced at $38 from Ocean Reef direct. I prefer the SAV and there is a skill video located on [@] instructing you on how to breathe off of a regular oct if the situation should arise. Watch the video first to make sure this FFM is right for you but it truly brings diving to a whole new level and is well worth the money and all you need to dive is this mask with any 1st stage and you are ready to go.

To many add ons

I did end up returning this mask,[...] When you get the mask it automatically needs expensive add ons. You need to buy the specific 1st Stage, you also need to buy the Oct adapter, why you would even sell a mask without this I am not sure. This mask is not usable when you receive it, at least not safely.

Ocean Reef Neptune Space G Full Face Mask

Finding Your Perfect Fit

The Neptune Space is available in two sizes, Small/Medium and Medium/Large.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, the customer may use the calliper to take two simple face measurements. Using the Full Face Mask Size Recommendation Chart, he or she can evaluate the size category into which the measurements fall. There are three different size categories on the chart: Small/Medium, Both, & Medium/Large. If the measurements fall within the both category, then the diver should technically be able to wear either full face mask (M/L or S/M), and in that case 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 G.divers mask is available in 2 sizes and 4 color options and includes an integrated balanced 2nd stage regulator with a 3/8" threaded 31.5" (80cm) low pressure hose. The patented bellows style face skirt, molded from premium grade silicone rubber, uses a spring profile and large sealing double the size and spacing (30-45mm), 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 G.divers full face 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 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. These unique face seal and strap concepts are Ocean Reefs patents.

The streamlined visor, made of transparent polycarbonate, is designed to be wider and sit closer to the face than previous full face masks. The G.divers design maximizes the visual field, particularly the peripheral area. The visible light transfer of the visor is 92%. These factors give divers an astonishingly clear view of the underwater world. Mask comes with an owner's manual.
