This is the brand that the Chinese copies are now ripping off.

Operating Manual/Catalog for "Ocean Reef" Full Face Mask
https://snorkeling.oceanreefgroup.co...rt-2018-LR.pdf

The "Easybreath" mask may be the first of the modern versions using polycarbonate lenses as the viewing lens here is curved like a fish bowl, later masks build flat planes into the lens to bring a less distorted image to the diver.

I feel like someone should point out that these masks are deadly. The lack of air flow has people reporting light headed etc. I just wouldn't touch or promote these things.
Putting these out here this casually will get some idiot to use one and blackout.

Just my 2 cents.

Maybe, and I understand the physics and the physiology, but the regulators would have been onto these like a shot if they were that bad. Some years ago there was the rather attractive plastic and complicated looking "Diveman" self-contained breathing apparatus, it was powered by your legs pumping up and down, but once the government regulators took a look at it they fell on the importer like a ton of bricks. Banning followed and the importer was in big trouble as any fatalities and the prison cells beckoned.

In fact just found one for sale https://www.worthpoint.com/worthoped...water-18553774
In some jurisdictions the seller would be committing an illegal act and face a heavy fine, or jail term or both! That is the way to get rid of dangerous gear, however these masks (the better ones, not the rip-offs) have been around now for 3 years. I don’t recommend them, but it is a free country and within the law people can buy what they like.

P.S. A diving professional evaluated the "Diveman" in a swimming pool under supervised conditions with the whole thing being videoed. His conclusion on surfacing was that he could maintain airflow, but if he had to work harder underwater then the effort of using the "Diveman" went up to boost the now increased oxygen requirement. This in turn put him under increased stress which would escalate into a highly dangerous and easily fatal situation. This guy was a fit and strong individual and a highly experienced underwater worker and he roundly condemned the unit then and there. The axe came down almost instantly the program aired and fearing public safety was at risk the authorities went searching for the perpetrators.

Someone posted here or elsewhere about having to put the pedal down against some current and when they got to the beach their lips were blue and they passed out or came close to it. I donít doubt the regulators would come down hard, but how many people are putting in hard work in their goofy full face mask?
If theyíre all coming from China who knows how bad some are.

Looks like more loopy ideas are on the way, while looking for the "Diveman" reference I stumbled on this one.

https://www.ebay.com/itm/Underwater-...Arco:rk:7:pf:0

A bit of searching shows that where a buck can be made there are plenty of people willing to talk up this "new" aquatic gear.

https://www.spotmydive.com/en/news/r...-one-to-choose

The key aspect of dive gear such as masks and snorkels is that they can be removed in a flash if things are not working, same idea as bailing out of any equipment such as scuba. These "new" gadgets tend to lock you in when split seconds may count and when there is no support crew as you have with more complex professional dive equipment. The appeal of these devices is they vaguely ape more professional gear, the operative term here being "ape". Mimic may have been a more polite term, but some of this gear can be summed up as "monkey see, monkey do"!

In the interests of science I purchased one of the low cost versions as anything that they charge 150 bucks for will not have any corners cut, however for under 30 bucks US who knows? One aspect I went for is a push button disconnect on the rear head straps as getting these things off in a hurry is vital. I am going to wear it mowing my rear lawn and see how the air flow handling of the snorkel mask accommodates more strenuous activity. I don’t intend risking my neck diving with it, plus being an object of derision down at the beach!

The "Ahooga" horn moment is when you see ear plugs dangling on plastic filament connectors on either side of the masks!

Nice equipment on the model by the way of general observation!

Well as luck would have it the Enkeeo full face mask arrived today. First impressions were it looked well-made and styling and parts fit were excellent, but as soon as I took the wrapping off I felt the plastic which was hard and shiny like styrene plastic, especially the clear parts. Now polycarbonate plastic tends to have a slight grey cast to it, but this stuff is crystal clear and its durability may not be so great especially in the school of hard knocks. It is obvious that a diving pro never had a real good look at one of these masks as in seconds I could see where its problems lay. You can stick your index and middle finger with some slight room to spare in the rectangular cross section snorkel barrel on top of the mask, but where it pipes down into the mask you could barely push your little finger in there and holding clips at the entrance inside the mask make that impossible anyway. Note quite round, but rounded, that air flow pipe runs down the centerline of the mask between your eyes for about 4 inches and that is a big restriction with a relatively small bore for a snorkel. So without even putting it on my head I can tell you that strong exhalation will have air rebounding and swirl back in the oro-nasal section of the mask and will build-up carbon dioxide because where it counts the snorkel bore is way too small. I use a big bore snorkel and using this Enkeeo mask would be tantamount to breathing through a half bore or less snorkel, plus the extra drag on air flow as it whips around the bends and turns. So low power, low effort, slow breathing only as the snorkel bores aren’t big enough. Half diameter means a quarter of the cross-section and for airflow through a snorkel it is the cross sectional area that counts for a breathing tube.

Now you know why in the old days full face masks had two big snorkels on either side of the mask looking like antlers, you just cannot do it with these nicely made, but basically restricted, single bore snorkels. Once air flow goes turbulent you will be hard pressed to push exhaled air out and replenish with clean air on each breath, while at a slow rate and a laminar flow you might just keep the carbon dioxide build up low enough for pottering around. And to think of all the personality diver bloggers who give these things the thumbs up they should be ashamed of themselves.

The masks do work, but not well enough because they need a constant diameter and bigger bore snorkel where it counts, near your nose and mouth. As for the snorkel non-return dry valve on the top, well it may be adequate, but the bore diameter is the Achilles Heel of these very techno-styled full face masks and they are not fit for use in anything but millpond conditions.

I guess kids play and swim around in such calm conditions under adult supervision and like kids everywhere they like the coolest and latest stuff that they see the other kids are using, like yo-yos and spinning tops from yesteryear these things are a fad and a quality mask and snorkel should replace these gadgets once the novelty wears off.

Here is the owner's manual for the Enkeeo full face mask and to be fair they do give you warnings, but you only see them here in detail after you purchased the mask.

THE LAST DIVING MASK YOUíLL EVER NEED
my comment: or maybe the last that you will ever use!

These sure arenít your great grandaddyís swimming goggles! This ultramodern twist on underwater specs, called D-Mask, addresses many of the issues divers currently encounter. Secured around the forehead, jaw, and chin, the design may cover the full face, but the result feels less restrictive than traditional goggles.

While itís usable on its own, by simply connecting the unit to an air tank, users can breathe easy and more naturally without the need of a sealed mouthpiece. Itís also equipped with an innovative bone-conduction radio system that makes it possible to enjoy tunes or communicate with other divers conversationally Ė something that was impossible and limited to basic sign language before. Other cool features include built-in LED headlamps, and a head-up projected display that indicates water conditions, depth, pressure and weather all on the front shield.


There is a snorkel version, photo of snorkel is attached.

The D-mask certainly looks futuristic, but the view from such a fishbowl perspective is going to be distorted. As a gas supplied mask it might breathe OK, but if it did then full face masks with oro-nasal insert masks have been wasting their time, yet somehow I do not think so! When Commander Le Prieur was developing his "scaphandre" apparatus, the first scuba, the full face dive mask was free flow with air exiting via the mask flanges at the sides. Under these conditions there was absolutely no chance of carbon dioxide build-up, but of course such systems were wasteful of gas in a limited supply carried by the diver, especially at depth.

Interesting that you don't want to be laughed at at the beach, but are willing to where a full face snorkel and mow the lawn where the neighbors can see you.

If I see the neighbor cutting their lawn with a snorkel mask, I am convinced someone is chained up in the basement. Or maybe they lost their tin foil hat.

Actually none of the neighbours can see into my rear yard, hence the choice! Window sill height minimums and local overlooking rules have seen to that. However once I saw the snorkel bore restriction, something you don't really see until you are actually holding one, I dismissed any idea of trying it out. The choice of scratch-prone plastics means that a careless owner will soon start degrading their mask, but the response here is why not simply buy another one? Recently I renewed one of my pro-dive masks and it cost me a 100 bucks on special, so you can see why, for the moment, people are queuing up (misguidedly) for their $29.99 full face masks with a snorkel included for nothing.
