  • Scubapro Full face diving mask

    The full-face dive masks are the next big thing in diving!
    ...but should you make the switch?

    Here's the Pros and cons of scuba diving with a full face mask.

    Previously full face diving masks was reserved for scientific and commercial divers, but today a growing number of recreational divers are making the switch to full-face diving masks.

    Are you looking for a Full Face Snorkel Mask instead

    Accordingly, a number of producers of full-face diving masks have started making “entry level” products, cheaper masks aimed at the recreational diver

    There are number of advantages to these, but also some drawbacks, and even some concerns.

    A full-face mask is, as the name suggest, a dive mask that covers the entire face.

    Rather than having a dive mask covering your eyes and nose, and a regulator in your mouth, you combine the two.

    By integrating the regulator into the mask, the diver doesn’t have to hold on to the regulator in the mouth, and it frees up the mouth for talking.

    This can be done with a special underwater radio intercom system.

    "With integrated underwater intercom systems, you can talk to your dive buddy, the surface boat, and anyone else who is on the same channel"

    一本道高清幕免费视烦-The pros of a full-face scuba mask

    伊人影院蕉久影院在线99-You can talk

    Probably the main reason for a lot of those who switch.

    By integrated underwater intercom systems, you can talk to your dive buddy, the surface boat, and anyone else who is on the same channel. A huge advantage to divers doing search and recovery, or any other activity that requires better underwater communication than standard hand signals can manage.

    欧美三级-More securely attached

    Instead of just a single strap holding the mask in place, the full-face mask has several independent straps that need to be placed around your head, making a mask loss much less likely.

    日本一本免费一二区-Less risk of losing regulator

    Because the regulator is integrated, there’s less risk that a diver will lose the regulator by accident during a dive. And for people with some form of dental or jaw problem, it eliminates the need to hold on to the mouthpiece.

    伊人影院蕉久影院在线99-Larger field of vision

    The best full-face dive masks allow for almost 180 degree vision, more than any traditional dive mask.

    欧美BBwHD-The cons and concerns of a full-face mask

    一本道高清幕免费视烦-Harder to clear

    欧美三级-A full-face mask is less likely to flood, but it does happen. And when it does, it is that much harder to clear, due to the larger volume. And the fact that breathing may not be possible as long as it is flooded, depending on how much water is in the mask.

    欧美BBwHD-Harder to put on correctly

    The several straps involved means that putting it on is trickier than with a traditional mask, and if not placed properly, it may flood or fall off.

    欧美BBwHD-A dropped mask becomes critical

    Drop a traditional dive mask, and you can typically take your time searching for it and putting it back on. Or simply pull a reserve out of a pocket.

    Drop a full-face mask, and you lose both your mask and regulator, so suddenly you need to move that much quicker.

    The regulator hose will thankfully tether the mask to you, so finding it should be fairly quick.

    伊人影院蕉久影院在线99-Skills deterioration

    I’ve dived with a few full-face mask enthusiasts who had managed to forget some of the basic hand signals, because they were used to being able to talk to their dive buddies.

    But when they found themselves diving with divers who weren’t using a full-face mask, or when the intercom system in their full-face mask wasn’t working, they were struggling to communicate.

    The same could be said for basic dive skills such as mask clearing of traditional mask or regulator recovery techniques. This could become necessary if using a traditional mask for whatever reason.

    欧美BBwHD-Cost and weight

    Full-face masks are expensive, with prices ranging from $600 to $1,600 for a mask. And they are of course quite a bit heavier for dive travel than a traditional mask. And for maximum benefit and safety, and additional course in using your new full-face mask should be considered, typically a cost of $500 or so.

    日本一本免费一二区-Chatter underwater

    This is more of a concern than a problem, and definitely a matter of taste. But while I see, and have experienced, the advantage of talking to your buddies and dive boat while doing a complex dive, such as a search for a wreck.

    I still like the serenity and peacefulness of diving. No one can talk to me underwater, and I quite like that. A full-face mask would to some extent take that away, and personally, I wouldn’t like that.

    1. Rickey Keyser

      I’ve been diving using a full face for some two years now, and it’s a complete game changer. Once you go full face you never go back.

      If you go with the communication system make sure to get wireless, the wires doesn’t work well with diving on a reef or wreck.
      I wouldn’t say I started chattering more with this system, I make clear communication, without misunderstandings, and we don’t talk just to talk. Some divers might do so, but I haven’t experienced it yet.

      • Torben Lonne

        Hi Rick,

        nice to get some pros for the full face mask. Are there no down sides to full face vs regular mask? It would be nice with another side to this point as well!

        \Torben –

        • Rich

          They are a real step up, however fit can be a problem. Here is my take:

          I am a Divemaster in the Keys and own a PADI Approved Dive Boat. I stopped counting dives at 1200. I purchased the Scubapro, Ocean Reef Neptune, and the OTS Guardian, all with Buddy Phone Communication. I have 2 topsides by OTS, one digital one not.

          I am a big guy, 6’4″ and fit was a problem with all of the masks.

          I have not yet dove with the Scubapro because the fit seems so poor for me it doesn’t seem worth it, but I will eventually.

          The OTS barely fits my face, but the silicone makes a great seal even with my goatee. I had to get the larger nose pieces but even them I have to push the whole mask up to clear my ears. I have to reposition the mask 3 or 4 times during the dive. With that said I have never had a drop of fog or water in the mask, it breaths easily, visibility is great and the communications are very clear. It will drop your first word, so start off slow. I will repeat my buddies name twice when I begin communications. So, bit of a pain, but well, well worth it. I just wish they made a bigger mask (I do believe they make two sizes and this is the larger one)

          The Ocean Reef I did not like at all. I tried it twice. While it did seem to fit better, the first time I was inspecting my boat hull and the reg bounced when I breathed in. This did not stop, but I figured it might have been because I was near the surface. Any time you try one of the masks it is a little stressful anyway, so I couldn’t wait to get it off. I was also told that the communications that came with it did not sound good at all. Again, because I was near the surface (5 feet)? I tried it a second time yesterday and hated it. It seemed very buoyant and pulled on my jaw. I spent 10 minutes trying to make it comfortable but just gave up.

          I have a friend we have dove with for 15 years (lots of commercial diving, we are all pretty seasoned), well over 1000 dives and he dove the OTS once successfully but got a little freaked out and won’t try it again. My wife has the same OTS as mine and loves it and has never had an issue.

          Hopefully this helps someone. Overall, I love the OTS but just wish it fit better… I should give the Ocean Reef one more try…


            What do you do about dry mouth, it’s a huge issue since I switched.

            • Joe

              I dove for 10 years with no problems even though I’ve always had allergies. Then around my eyes began to puff up after a couple dives the morning after. So much they would almost be shut. I believe its the water getting into my sinuses. Is there anything that won’t leak so I may be able to resume diving again??

          • Michael

            I have the ocean reef g divers and also find it a little bouant and hard on the jaw.

          • Jeffrey Bohémier

            I have the Ocean Reef Predator. When I first dove it I thought I may have made a really expensive mistake. It also seemed to be too small for my face. But considering the amount of money I had in it, I tried it again and again and again. Now I’ve gotta say, I absolutely love it. It slowly molded itself to fit my face. It doesn’t leak a drop, and that’s remarkable considering that I’ve got a full beard. I can’t imagine having to go back to a regular mask. I particularly like the fact that it NEVER fogs up and jaw fatigue has become a thing of the past. Additionally, I like knowing that my mask is secured to my face so no clumsy diver can knock my mask off with his fins. Give the Ocean Reef several more tries. It’ll fit your face a bit better with each try.

      • Oliver Fineran

        Totally agree with your comments Rickey. I swapped to full face a year ago and can imagine ever going back.

        Pros / Cons for me are:

        1. I feel more relaxed breathing. Obviously, you can have your mouth open or closed, or breath through your nose.
        2. I’m using Oceanreef and i find the visibility compared to my old mask is vast.
        3. Never used the comms, as my wife fell pregnant the week after we brought them. Hopefully, get to try it out soon.
        4. I have filled mine with water in training, which is very hard! (the plenum is equalized every time you breath), you literally have to take it off to flood it. When flooded the purge button will empty the unit in seconds.
        5. Carry a spare mask for emergencies.
        6. My mask has never fogged (UAE and Oman Waters).
        7. Setting up the mask for first use is challenging. Adjusting the equalizing systems is takes a while till your happy.
        8. Worth getting the surface breather valve.
        9. More bulk to transport.
        10. Once back in the boat, i feel a lot more comfortable after the dive.
        11. i have a quick release on my mask. Easier to handle and store.
        12. Some report a little more gas usage. I don’t find this.


      • Keith

        How do you size the mask?

      • Jeffrey Bohémier

        Amen to that. I purchased an Ocean Reef Predator and can’t imagine having to dive without it. It makes me feel more secure in the fact that nobody can cut in front of me and accidentally knock either my mask off or my regulator out of my mouth. My jaw isn’t tired after dives either, which makes a huge difference when you have to deal with TMJ. Additionally, the field of visibility is drastically improved. Having a mask that’s constantly fogging up is a thing of the past. I can’t make this mask fog even if I tried. And last, but certainly not least, my mask doesn’t leak a drop despite having a full beard. My regular mask would often leak with just a mustache. You’re comment that once you go full face you’ll never go go back is absolutely true. I don’t have a communication system with my mask yet, but will gladly get one when I start diving with another diver with a full face mask.

    2. Nicolai Loenne

      Nice review of full face masks Thomas 🙂

      As I see it, the biggest drawback in my book about these masks, is the lack of peace and quiet. As you say, that’s one of the nicer parts of a dive and I would hate to lose that.

      • Jack

        So don’t get a comm system. Problem solved.

    3. Dawie

      I use a ffm and love every second of it. Did a 4 hour dive a week ago and did not once think clear mask defog mask ajust mask. Take reg out wiggel jaw get comfy. No for 4 hours i just dived. Do the training do the skills often and dont say it will never happen to me. And you will enjoy every second of the dive. As for comms you dont like ot then dont take it dive with the mask not the comms.

      • Torben Lonne

        Hi Dawie,
        That is a pretty good recommendation: a 4 hour dive with no discomfort.
        And yes if you don’t like it don’t go, it’s just hard to know if you like it before you go.

    4. Sarah Boness

      Whether with the comms system or without Full Face Masks are indeed the way forward. With the greater field of vision they provide over conventional masks they are perfect for all types of diving. Diving with Ocean Reef FFM without the comms as like some of you have said I don’t want to chat but they are a good idea for using in open water with students so Instructors can communicate with other Instructors & Dive Masters as well as with the surface cover.
      Clearing a FFM is easy & hassle free in less time then it takes to clear my old mask.
      Yes a spare mask is advisable as a back up but with the correct training by an approved training centre a bail out becomes second nature as with all emergency procedures that we are taught to deal with throughout our diving lives.
      Great benefit for cold water divers FFM keeps your face nice & warm compared to conventional masks.
      Try before you buy with a Discover FFM session & decide for yourself if it’s the way you want to dive in the future!

      • Gunner

        Where can you get a DFFM session? The dive shops where I live are all against these masks and throw up all kinds of road blocks to using them.

    5. Andre

      I have been diving FF for over 10 years and your so-called concerns are nothing compared to the benefits.
      Your main reason for diving FF Mask – You can talk??? Huh?? C’mon what about Safety, Better Vision, Natural Breathing, No Leaks and no fogging??
      Underwater Comms is just an additional benefit that is brilliant for safety and actually helps you to see more as you can be quickly informed of activity that you would have missed by looking in the wrong direction…

      I really think your Cons of FF Mask diving are made up theoretical reasons and not from practical diving experience..
      ..Harder to clear??? uhh – you get so little water in it you hardly ever have to clear the mask and when you do for some weird reason get water in the mask you simply push the purge button – easy..Masks like the Ocean Reef have a drain/exhaust at the bottom so it clears it self.
      …Harder to put on??? uhh – it gets easier the more you do it – how many times do you want to put it on and take it off during a dive? If it’s on – it’s on – it is not going anywhere unlike a normal mask that can get kicked off or brushed of by another diver..
      ..Dropping a Mask???? What kind of a reason is that? Please explain the context for the con? How on earth do you drop a FF Mask when it can’t even be kicked off your face by another diver whilst diving – ??
      ..Skills deterioration?? Huh?? c’mon – this is another dumb reason, not all FF mask divers have comms and you do not only dive with divers using FF Masks so this is another weird made-up con to have some words on a page..Basic skills deterioration ?? Signals , reg retrieval ??? Regulator / octo retrieval is one skill which is part of ffm diving and if your kit is properly configured you know exactly where your octo is.
      I really think this article does not give accurate and informative information about FF Mask diving…..cheers.

      • Torben Lonne

        Hi Andre,

        Thanks for your side of full face mask diving. It’s wonderful to get another side of it, and as I can read you are a big fan of FF mask. I’ve never tried them, so can’t set my self up as an expert, but the concerns you can’t take away from a diver, and they can never be made up. And as Thomas mentions in the article, he has tried diving with FF divers that has forgotten basic signals, not saying that this is standard, but it is a concern.

        I can see your point with the mask not falling off, when it’s strapped more securely. Do you train no mask/mask off procedures regularly? Here my concern would be if it normally doesn’t happen it’s not a skill you are good at if it should happen.

        I rally think there’s a bright future for the FF mask, and I’m really looking forward to seeing where the trend goes.

        By the way: Is it possible to dive with full beard? How is the leak on that?

        Thanks for sharing your side of the full face diving!

      • Chris McConnell

        Awesome review and the 10+ years experience carries a lot of weight in my book.

        • Lea Hawkins Gonzales

          I am thinking about getting service in scuba diving. I have snorkeled with a full face snorkel and love it. I have dentures and a regular mask presses on my upper lip which hurts and makes getting a good seal hard, and it’s hard for me to hold the snorkel in my mouth. It’s much easier to have it all in one and nothing pressing on my lips. Can anyone who has dentures let me know your opinions.

      • Krista

        Hello Andre, What type of FFM do you have? I would like to get one for myself and my husband, and your experience will help with this purchase for sure!

    6. Andre

      Hi Torben

      I believe that one should always get back to basics and any diver should practice FF mask removals and replacement. If one does not use a bailout block for switching gas mask removal will be necessary to place the octo. One tip I can give is that you should always wet your face before using a FF mask as cold water can be quite a shock on a dry warm face!

      Concerning diving with full beards – no problem – normal masks do not seal if you have an mustache etc and this is not a problem with FF masks – I have friends diving with full beards with no leakage – the wide face skirt seals very well. (Just be careful of getting hair caught in bottom buckles when removing 🙂 )

    7. David Pearce

      I got my wife and myself full face masks. It takes a little getting used to initially, but once you do, it is worth it. For me, two big benefits stand out: I can breath through my nose (no jaw fatigue) and I can use my multi-focal lenses in the mask! No more hassles with contacts! Field of vision is great too, but other, less expensive masks offer that too.

      Putting it on and having to carry it around with you is a drag, and if it is not fitting properly, equalizing is tricky. It is also very expensive compared to other masks. We do not have the comms unit so chatter is not an issue.

    8. Gregorio Coye Beeks

      Thanks for the update on the fullface mask Torben, some day would like to get one,

      • Torben Lonne

        Hi Gregorio, we’re glad you liked the article, and hope you’ll return for more great updates.

      • Wendy Dickie

        I’m an allergy sufferer and often have to miss divine g opportunities due to stuffy nose.
        I’m assuming that if you can breathe through your nose, then you can clear light congestion in the full face mask? This would change my life

    9. diverkim

      Really informative article with lots of good comments. The first thing I thought of with oral communication underwater is enhanced safety, and I think that is a biggie. If the ffm becomes more reasonable in price, I’m sure I’ll get one.

      • Torben Lonne

        Hi Diverkim, thanks we’re glad you liked it. It’s true that communication, and especially communication surrounding safety issues, can be enhanced with talking communication. I’m quite sure that the prices are lowering with time, and as it becomes more mainstream

    10. Noel Ong

      As curious as other divers I bought a (not so expensive) FF. I just have a jaw problem that time so, for me to make up with a scheduled dive , I bought one. I guess all that I’ve heard in these comments are true, Its fun, new experience breathing underwater on your nose, securely holds to your face, etc. , but the thing here is, if you really want to use these gears, first you have to really practice and practice to make perfect dive. Lesson learned, I’ve dove with a ff for the first time, and have to go to the surface in 15 min. because of improper use. I have to take off the mask and start to breath in my dive buddies’ spare ascending with out a mask and completely no air. hahahah what a first time experience. I found out that the mask aint properly fit in my face . the hood and some strands of hair made water flood the mask and before I knew it had lstt a lot of air.

      • Torben Lonne

        Hi Noel,

        Thanks for sharing your experience. Are you still using the ff mask?

        I guess it’s something that goes for all aspects of diving. If you’re not trained properly then things can go wrong. It’s good that you knew your backup procedures and were able to ascend safely.

    11. Martin de Weger

      I’ve been diving with a FFM for a few years now. I do like the fact it is silent under water. Most masks don’t come with a com set as a standard. Even when you use a com set, you can use it for urgent matters although the same can be said about cellphones…

    12. Seal

      . It has some excellent points but I disagree with some of the cons the author presented. He states; That it is harder to clear. With the Ocean Reef mask all you have to do is look down and hit the purge and it clears itself. Harder to put on. This is a case of being properly trained in the use of the mask. The Ocean Reef mask with the six strap placement is easy to put on and adjust and fast to get off in an emergency. Dropped Mask Here again the Ocean Reef mask with the six straps makes it more secure than other full face masks so there is very little chance of have a dropped mask. Chatter Underwater The mask can be used without a comm. system and if you do like to listen to anyone else you can always leave the battery out. The group I dive with or pretty conservative using them but realize that it nice to have them when needed. I do notice that there is more chatter when it is new to a diver but seems to subside with use.

    13. Seal

      I have been diving the full face mask for work and teaching for about 15 years and I am an instructor trainer in the FFM.

    14. Gregorio Coye Beeks

      Thanks for the info. we have used this fullface mask which is a wanderfull piece of equipment for diving,and I personilly would communicate to all divers that it is good and safe.

    15. Jeffrey Bohemier

      Wow…reading the negatives make me think that the writer is afraid of improvements in dive gear. I have no doubt there were negatives when switching from horse collars to BCD’s too. The first BCD’s road up horribly. But regardless, they still offered better lift and overall, were safer. I see the same with using a full face mask. Its far less likely to get kicked off your face, is actually easier to clear, eliminates jaw fatigue, and yes, you now have the ability to communicate with others. This can become crucial if you find yourself in trouble and your buddy happens to be elsewhere instead of watching you. Now you can simply call out for help and tell your buddy where you are, the problem, etc… I don’t have a full face mask. BUT…I’m getting ready to purchase one. I’m just not sure what the differences are between the Ocean Reef Predator or G mask.

    16. Martin de Weger

      The G mask is the entry level mask with a plastic frame while the Predator is a more professional mask with a stainless steel frame and parts on the regulator. If I’m correct the g-divers series has a warranty period of 1 or 3 years. The predator (and other non- G-divers serie masks) has a lifetime warranty(but my info is a few years old).

    17. Jeffrey Bohemier

      Thanks for the information. The sales brochure doesn’t really describe the materials they’re made of, but I found a comment by another diver that had the G mask and upgraded to the Predator. He stated that the difference was night and day, that the Predator was a far better mask. Of course, its more than twice the price as well. However, it should last for years and years. My new Predator mask is on order and should come in sometime this coming week. Next purchase…a new drysuit. I’m looking at the Fusion Bullet with the upgraded silicone seals, as the Waterproof D1 hybrid doesn’t come in my size.

    18. Aaron Kelly

      I used a FFM to propose to my girlfriend. Worked great, and I love everything about using a FFM except the price. We rented the ones we used. Eventually we’d like to buy a pair, but with comms they are quite costly. So far, we’re still using regular gear for our normal diving.

    19. PsyDoc

      Wonder if people with the experience of diving regularly with FFMs have an answer to this: Do Ocean Reef masks use increase gas consumption as compared to a normal regulator.

      I have spoken to Ocean Reef and they say their masks don’t increase gas consumption. They however state the consumption is only increased if (1) The diver hyperventilates due to the anxiety of using new mask (2) The communication is used (3) The diver breathes both with nose and mouth.

      Other experts state no matter how good the mask is, the gas consumption will be higher than normal regulator, because of mild hypercapnia resulting from the mixing of the gas and CO2 within sub mask (the mask with in the main mask which sits on the nose and mouth)

      Any thoughts?

      • jakrbt

        I’m very curious about the gas and CO2 mix insie the sub mask. Not sure this would be an issue at all because just like with a conventional regulator, all exhaled gas (CO2) is being purged out through the regulator. And like on my OceanReef G. Diver, there’s a purge valve on the bottom of the mask so the chances of there being any residual gas still left in the sub mask are very slim at best. I have not found that I use any more air with a ffm than I do with a conventional mask & regulator.

        Something else to consider. Cost. Are full face masks expensive? Yes, they are. Until you consider the cost of buying a good conventional mask and second stage regulator separately. A good mask (Atomic, etc.) will set you back somewhere in the neighborhood of $100-$140 USD. A good second stage regulator (Atomiz, Zeagle, ScubaPro, etc.) will set you back $250-$600 USD. So once you buy both of those, you’re already into ffm territory or at least nearing it anyway.

        As for a ffm being more difficult to clear, it really depends on the mask. I make it a habit when I’m just doing casual diving (lakes, etc.) to don and doff my ffm underwater to ensure I’m proficient at it should I ever need it. Usually I doff the ffm and switch to a conventional mask and 2nd stage. And then switch back. My OceanReef has six straps to tighten and as soon as I place the mask up to my face and start to exhale, it’s already clearing. By the time I have all 6 straps tightened to my liking (takes literally seconds) the mask is completely clear. I do take a very shallow first breath just in case, but I’ve never had it be the case where I still had lots of water to clear out before I could take a breath. Not only that, but there have been times where I’ve mistakenly left the surface air valve open during descent and then gotten water inside the mask. It only enters while breathing in and very slowly at that. You can hear it bubbling as you breath in and as soon as you realize it, all you do is close the valve and exhale normally, pushing any water through the purge valve. Never in the year and half that I’ve been diving my ffm (at least with the OceanReef anyway) have I had a single instance where I couldn’t take a breath in because the mask was flooded.

        Now diving a ffm isn’t for everyone. They are a bit more cumbersome on your face. But you eventually get used to it. For me at least, the benefits far outweigh the drawbacks (not that I see any really). I’ve gone the way of the ffm and won’t be going back any time soon!

      Although this is an interesting article (thanks Torben), it’s the really great feedback in the comments that I find the most interesting.

      After purchasing a couple of ff snorkel masks for our young boys for Christmas, my husband (who’s been scuba diving since the late 80s) tried on one of their ff masks. He was immediately impressed, so we’re now looking at full face diving masks for ourselves. I have problems with jaw fatigue so anything to reduce the pain afterwards would be awesome, and would consider well worth the extra money spent. These already sound like a winner.

      I appreciate the comments addressing the safety aspects that were raised in the article, and we’ll be looking to hire some initially and get the extra training. Thanks everyone!

      Apart from all the pros and cons mentioned I have found that the biggest benefit for me has been reduced blocked ears because I can breathe normally using my nose as well as my mouth. Using a convential mask I would quite often have problems when surfacing and my ears suddenly blocking in the surface layers or when dive depth has varied throughout the dive, this doesn’t happen with the FFM. It’s probably a form of reverse block as I never have problems with clearing ears and it usually happens in the top 2 metres or so and when breaking the surface. I used to have to clear a ton of gunk from my nose at the surface, now I don’t need to anymore.

      Folks, I am an ex military diver (1980s) with little experience of modern sports dive equipment. These days I am a part time inventor and have devised a system to convert spoken words to written text which are presented on a small waterproof LED display. I have not yet tested it in earnest underwater but would appreciate the opinion of experienced divers on whether this would be a useful comms solution – or not?

      • Will

        As an instructor, the ability to display speech as text would be useful. However, the price point would have to be competitive with a standard underwater slate. One problem I see is that your system would only allow simplex communication whereas a slate can be passed back and forth for 2-way communications.

    23. Colin Langston

      Thank you for your input Will.

      You are right that the communication is simplex or one way – but that is per comms unit.
      In other words, if each diver’s face mask is fitted with the device, then each diver can speak.
      It would take a little discipline to take turns to ‘send’ as in normal, above water radio comms.

      The other advantage over a slate is that the display is almost a real time transmission of the diver’s spokens words – so effectively a conversation.
      Not that we want to encourage too much air-consuming waffle down below!

      Further thoughts welcome. I need to decide whether to invest more time and money in its development.

      • Will

        The idea is okay but I’d be concerned with marketability. Why wouldn’t low end consumers just use slates while folks with a bit more cash opt for wireless audio comms rather than your speech to text system? What is your target price point and who is your market?

    24. Evan Rogers

      I dive with my drege all the time I’m thinking about a full face with com

    25. DAK

      I have the G-Diver FFM with SAV, no communication system. The only time I use my standard mask and regulator is when doing situational drills for proficiency. It’s not for everyone, but if you have TMJ issues or simply get jaw fatigue it’s the way to go. Always carry backups. I use QD for switching between FFM and BU regs, keeping the octo for intended use. Spare Air is another option for those who don’t believe it’s worthless 😉

    26. Chris

      Is it any easier to equalize your ears with a ffm? I was thinking that it might be because you can breathe more normal, I know that you will still have to equalize.

      • Dak

        As easy, not easier. If you set up you FFM correctly up front, there should be no issues with equalizing. I can only speak of my experience with my Ocean Reef, two nose plugs align with your nostrels, a little push on the face of the regulator housing allows quick and comfortable equalizing.

    27. Darren Hedges

      If done correctly, an Ocean Reef IDM is almost clear of water almost as soon as you have put it back over your mouth and can resume breathing from it straight away. If you mess the skill up then literally a couple of seconds and you can start breathing so either way it’s not an issue. You really really have to try hard to get them to let water in.

    28. Joanne Martin

      I have Bells Palsy (since November 2017) and found out the hard way that using a standard face mask won’t work with my new facial contours. Since I don’t know if or even when this disease may resolve, and I still want to dive, I’m considering a full face mask. Has anyone had similar issues, or reasons, for using the full mask option?

      • Peter

        Interesting re the facial contour change due to Bells Palsy, I have similar issues related, I think, to Parkinsens. I have purchased an Ocean Neptune full face mask and been testing in swimming pool. It definitely solves the leaking issues that I have been experiencing, Am excited by new lease of life that this provides to my diving through my 70s.

    29. Anders Gillian

      Thanks for your great guide.
      I’m currently looking to buy a Ocean Reef Neptune GDIVERS Space Full Face MasK – is that still one of the best ffm on the market?

    30. Xavier

      Hello everyone from Denmark. I dive with a full face since1999 in winter freezing waters or/and polluted work places only and have always a traditional extra mask in a pocket close to a my extra regulator (Poseidon) when I have a cold with issues balancing my ears going down. Then I use the regular very soft silicon mask and when on the wrecks or on spot down there I switch to my full face and empty it by “overpressuring” fast the second stage. It’s an EXO26, KirbyMorgan
      Conclusion; a good full face of your choice means more comfort in cold and dirty waters, no more frozen face and polluted water in harbors are the main advantages, radiocom and nose breathing are not that important for me , old habits and good old school I guess. Emptying a full face from water is easy, just train for it, that’s it as always. Think about buying a good swivel for the second stage and always have a stainless steel ring on your shoulder strap to clamp your full face when needed (back on boat, peer, or switching to a regular mask). Hope this helps, Xavier

    31. Joe

      Dive experts, one issue hoping eliminated but not mentioned so far… I had sleep apnea surgery that removed uvula & upper palate (uup) effectively equalizing pressure between nose and mouth. Afterwards, traditional masks leak & gets worse deeper we dive. I’m guessing FFM would eliminate this issue as both nose and mouth are in the same space/pressure.
      Is this true? Is there a FFM that address this better than another? Comments appreciated.

    32. Roger

      Will any FF work with the posiden rebreather?

    33. Karen

      Thanks for the great review. Can you tell me if there is often/always some degree of water in these masks? I don’t know if there is a FFM with a perfect seal. My husband is only allowed to swim if he doesn’t get any water in his eyes/mouth (immune compromised). He thinks a FFM snorkel mask will work, but seems to me they all would leak. Thanks!

    34. Charlie Kinsley

      This has been really informative, but would anyone recommend a 14 year old beginner diver use one of these?
      If so, which model would be a good fit for a child’s face?


    35. Sasha

      Thanks for the great article. It’s for sure the best piece about FFMs on the web I’ve read so far.

      Scrolling through the comments I noticed that most are given by ffm enthusiasts so sound kind of a bit prejudiced by being very pro ffm…so it would be unbelievably helpfull if anyone could give a balanced view on the following:

      – increased gas usage in ffm sounds very realistic (CO2 mixture probably can’t be eliminated completely by any design) unless you are the type of person that can do two dives in a row without refilling the tank (so you wouldn’t notice increased gas usage). that said how do you feed from buddy if you are using ffm? assuming you should connect to buddy’s octopus first stage, how fast/hard is that?
      – in ffm do you have to rely on equalizing without touching (shutting) your nose with hands? Sorry for my English…hope its clear more or less 🙂
      – are your head movements limited compared to normal mask? if so than how?
      – are FFMs recomended for begginer divers? eg I’m at 47 dives, would you recomend trying ffm? how many training ffm dives would you recomend before taking ffm to safari?
      – are FFMs compatible with nitrox?
      – what regulators do ocean reef ffms use? their own? I’m a bit paranoid about regulator failure so use the pricy ones (scubapro), is it possible to install a scubapro regulator to ocean reed ffm?
      – if you have to change ffm for normal mask underwater, where do you put ffm? it looks pretty massive…

      thanks a lot in advance

      • Torben Lonne

        Hi Sasha,

        I’ve tried to answer your questions here:

        – increased gas usage from using full face dive mask:
        No, this is not something I’ve experienced when diving, there might be some but not anything I really notice on dive time etc.

        – Feed from your buddies Alternate Air source when using Full face:
        To be honest, I’ve never tried it in a real “out of air” situation, but I’ve practiced this doesn’t time.
        Swim up, and make sure your buddy knows what’s going on. Remeber back to your first training. Big out of air sign!
        Then, grap the straps in the back of the head/neck and full forward/up to get it off(this depends on the mask you’re using). Close my eyes as the water comes in, peek them open to make sure I can see what’s going on – it’s often a good idea to be able to swim with eyes open without a mask.
        Grap the alternative air source, clear it and start breathing in with my mouth, out with the nose. This keeps the mind focused on not breathing in with my nose. If you want, you can also pinch your nose.
        Connect to my buddy, signal “okay” and “up” – start the accent.
        It’s not as easy as with a normal mask, but most divers should be able to do it. Make sure you practice it, so you know what to do in the case. Also, make sure your buddy knows what to do, especially if he/she doesn’t dive FFM.

        – How to equalize your nose while using a full face mask
        Depending on the model, you’ll either have a built-in nose plug that you press on to block your nose, other models will have a soft nose skirt. All in all, you can be sure, that it’s possible as all diver needs to equalise and many are depending on blocking their nose.

        – are your head movements limited compared to normal mask? if so than how?
        No, not in any way.

        – are FFMs recomended for begginer divers?
        For beginners, no, unless you used it in your training or you take up training with a full face mask.
        It really depends on your level of diving, your skills and “feel” in the water. Are you acustom to the water, the gear and diving in general, then yes go for it. If not, then start there, get used to diving and then take on a Full Face mask once you are sure you’ll be ready for it.

        – are FFMs compatible with nitrox?


        – what regulators do ocean reef ffms use?
        Their own or a standard regulator with an adapter. No problem to use Scuba Pro.

      • Bryant Turner

        The Mantis FFM distributed by either Gull or OTS is a very comfortable mask especially for adults with smaller faces or younger divers. It’s a very simple & comfortable design where the diver equalizes just as he or she would equalize with a regular mask. Simplicity is bliss!

    36. Kevin Correa

      I am thinking about trying this option out as the first dive trip I took resulted in a blown eardrum. Even in a plane the only way for me to equalize my ears is a big yawn, my ENT advised that is likely due to the size of the canal from ears to nose and throat, I assume he is right. If I bought a mask and got additional training from the dive shop would this make clearing by yawning easier or is it about the same? I am trying to figure out how to continue to dive and save my hearing at the same time.

      • Torben Lonne

        Sorry to hear about your ear. This might just solve your issue, but not a guarantee.

        My suggestions would be, as you suggest, try it with training and then do a slow dive down with the mask. If your ears start to hurt, then stop and accent.

      • Bryant Turner

        Full face or regular mask…I’d recommend you look into getting a full set of Doc’s Pro Plugs for scuba divers. Then find the best fitting size for your ears. Busted my ear drum before and couldn’t dive for years. Tried them and it made all the difference. Now I never dive without them.

    37. Paul

      Hi all.
      Love the commentary. How about a anybody just getting into the sport. Would the recomendation be to start with traditional mask or jump in with both feet ( no pun intented) with FFM? Sounds like even the more skilled of you have a bit of a learning curve. I guess the basic concern here is whether there would be any safety concerns starting out as a beginning with FFM?

    38. Maritime Opinions

      Nice. This blog is very perfect and usefully information.

    39. Robert Von Zuben

      Hi All , love the dialogue, I too have switched over to FFM (2yrs) using a ocean reef system- no comms at this time . I made the switch for a couple of reasons, I “believed” that I had a tiny advantage when using a ffm over traditional mask if for whatever reason I passed out I figured I still might breathe- I have no data to back this up just my perception, secondly I wear prescription glasses to see, so I wanted to increase my field of view and hopefully my clarity with a prescription frame insert. I love the fact that the system is secure. in my experience I did have to practice a bit for equalization and I did end up taking a ffm course which I felt helped boost my confidence as well. I do carry a back up traditional mask, in case of system failure.

    40. Justin

      I’m wondering how easy it would be to mod a full face snorkel mask to use in diving. Like if you just mount the regulator where the snorkl is. I definitely wouldint use it for deep water but I think if it worked doing 20ft would be OK.

      • Carl C. Ibsen

        Do not try to modify a snorkeling FFM mask to scuba. DO NOT DO IT. Unless you are looking for an “accidental” death for your life insurance policy. CC

    41. jessica

      Hi, I’m an open water diver, however I’ve had trouble with my ears after a flight about a year ago and was wondering if the full face mask makes any difference in equalizing, I have been cleared by a dive doctor that says I am good to try again however last time I went in the pool I still felt quite a bit of pressure, maybe being able to breath through my nose on a dive could make all the difference?

    42. Uli


      I’m sorry of this was already asked and I missed it. But I would love to make the switch to a full face mask for lots of reasons, easier equalizing just being one of them. When I went to a dive shop for some infos on it, I was told not to get one unless I want to get the entire gear. I only dive on vacation if I get the chance, it wouldn’t make sense for me to buy the entire gear bc and all, and take it on non dive vacation. So my question is do I really need everything to connect a full face mask or can it be easily connected to a dive shops regulator?

      Thank you
      Uli 🙂

      • Torben Lonne

        Hi Uli,

        It can’t be connected to all regulators, and you might run into a dive shop having a rental reg that won’t fit. So, yes if you get the mask, get a regulator to follow as well. You don’t need BCD and such, just the mask and regulator( basically only the regulator first stage, which then could be attached to the dive shops second stage, but I’m not sure if they want to do this for you).

        Side note: Often it’s possible to buy converters, but as dive shops have different regs from shop to shop, you won’t have much luck here.

    43. CC Ibsen

      Have been diving Ocean Reef Neptune II NIRA and Raptor for past 10 years. Like the fact that my lips do not freeze in cold water, and I can talk when I get out of the cold water, which it is here, all year, if you go below 50 – 60 feet. Like the communication devices, except in shallow water where the exhalation bubbles seem to affect the mic more. The deeper I go, the less problem that is. Not a scientist or engineer, so do not know why that is, but accept that it is what it is. I practice flooding and clearing on a regular basis, just so I can do it if need be. Been diving since 1965 and have owned and used many masks. Still have some of my old ones and enjoy looking at them, but use the OceanReef masks, virtually exclusively, now. Must say that I have never lost a mask, during a dive, but having the multiple straps adds to my belief in safety from having that happen. Sort of think that if that is the norm for the commercial divers, why not have that added security for the rest of us. Much like in times gone by when recreational divers were admonished to stay away from dry suits, because of their complexity. Now, the dry suit is the norm, for cold water recreational divers. Have mostly dived for recreation, but also for years (1968 – 2000 approx) as S&R and body/evidence recovery. One of the primary reasons that I switched is for the, in my perception, safety factor. Some of that is due to my having, somehow, grown older, having attained 68 years of age. I read the stats on diver fatalities and find that virtually all fatalities involve drowning. Many, if not most, have a precipitating event (shallow water blackout, CO2 overload, heart attack, etc). However, virtually all drown because when the precipitating event occurs, the regulator falls out of the mouth and they drown. With the FFM, the regulator and air supply, stay in place so that if it is possible to regain consciousness, one has a chance to do so. The cons that I have found with the FFM are only a couple. One is that it is a bit more complicated to don and doff, especially if you have already put your gloves on, so do the gloves last. The other main one is that it takes a few dives to get used to the fact that, with the increased volume of your mask, you have a, correspondingly, increased amount of bouyancy in the mask. That takes a bit of getting used to, since it feels like your face is tryiing to float. Overall, for me, the pros outweigh the cons. That might not be the case for everyone, especially the young.

    44. Carl C. Ibsen

      Post Script. If you choose to dive a FFM, ALWAYS have a back-up mask with you, and an octo reg or redundant pony bottle and reg, for emergencies. CC

    45. Brian

      Hello all!

      I’m investigating a FFM as a way to actually get into diving. Here’s the issue for me: I have a horrible gag reflex (yes trips to the dentist are always cause of unmitigated panic), and I have tried to put the standard regulator mouthpiece into my mouth, and just can’t do it. My GR is so bad that even the THOUGHT of it causes me to gag. I have other ‘phobias’ … claustrophobia most especially, and would not want to be fighting the GR, for fear it would feed other panics.

      My girlfriend is an avid diver and I would like to be able to dive with her, rather than take a trip and send her out on the dive-boat alone (well, not alone … just not with me)! I’m not concerned about the price, as whatever it takes is whatever it takes. The comments here are enlightening, and I know I need to do my research to get the right FFM and related equipment. A real problem I see is trying to find a dive shop where I can get fitted and good consulting on my choice, and while I can read-up and buy things over the internet, it’s not the same and for something like this (and given the cost) I don’t want to thrash about. I live in SWFL (Naples/Marco area) and my girlfriend lives on the other coast. Any recommendations for a shop to go would be appreciated. I want to start with a ‘discover scuba’ class, but I just don’t feel I’ll discover anything if I can’t use a standard set-up. So unless I’m not thinking straight, getting a FFM is the first step. If other things keep me from diving, well, c’est la vie. Thanks again for the great discussion!

      • Torben Lonne

        Hi Brian,

        A thought of concern: If you’re out diving and you run out of air, or your gear malfunction, you need to be able to use your buddy’s alternate air source. This is typically a standard regulator. When I read your description, and add a bit of stress of being out of air on top, I’m seeing a diving accident about to happen.

        If you’re still up for trying, try contacting a few dive centers in the area and check-up if they offer FFM for rental.

    46. Brian

      Good counsel Torben, thank you … last thing I want to be is an accident!

      I visited some dive shops this past weekend and will try a few smaller mouthpieces for a ‘standard’ regulator. In conversation it came up that I have successfully managed to snorkel with a mouthpiece, but typically those are smaller. One dive shop owner suggested I do Discover Scuba using traditional set-ups. He also sold me a small mouthpiece to take home to try out, seeing if I could just wear it walking around my home. I’ll give that a try. He also pointed to some bad experiences with FFM from a diver he knew, and cautioned something similar to what you said. It may be that I simply am not cut out for this sport. But I want to give it a try — while not tempting death in the process!
