About HydroOptix Mega 4.5 Mask

Flat Dive Masks Block 75% of Your View - The world's only Double-Dome dive mask conquers tunnel vision - Dive smart -- see almost 5X more!

HydroOptix Diving Masks
The Double-Dome dive masks' patented optics provide razor-sharp Panoramic Views, 350% greater than conventional flat dive masks, completely free of distortions, no matter where you look HydroOptix Double-Dome scuba masks give divers superior situational awareness and eye-hand coordination -- your time underwater becomes safer, more productive and enjoyable

NanoFOG coating ensures fog-free dives The Double-Dome lenses of HydroOptix dive masks are made from the same super-tough material used for bulletproof shields: Lexan+ polycarbonate Besides impact protection, the lenses resist scratches with the toughest hard coating available the same coating that protects automotive headlamps

Flat diving masks, once submerged, make objects appear closer and bigger than reality -- and cause off-axis blurring and shape distortion that's ten times worse than the MilSpec requirements for in-air vision systems All Double-Dome dive masks surpass MilSpecs -- having edge resolution that is over 100 times sharper than flat diving masks

Two Skirts are available for MEGA 45DD Mask
S1 Skirt: Diver with thick moustaches and beards prefer the shorter seal under the nose (fits above your moustache hair)
S3 Skirt: Unique Flex-Curves fit many face-shapes For those with prominent nose bridges

I love to have great visibility and this is the mask for it. Although I have to wear contacts to use it, the range of view it’s worth the problem. The only problem is its volume and that the mask won’t fit everybody. You won’t know until you try it.

HydroOptix Mask, too many quirks...

The lenses worked as stated...that's all that works...however!
I'm in my 50's, dived since the 1970's, worn glasses since 2nd grade. USCG/Capn/Instructor/Guide-Great Lakes/Cayman/Bahamas/Keys-1000's of dives x 6.
It will stick to the face during the in-shop, suck-in, test. DEMAND a NO OBLIGATION test dive!
I bought one to take to Hawaii. Leaks like a sieve. There are so many quirks to the care and feeding, of this thing, that it takes on a life of its own. I want to dive not care for a pet.
Lots of ludicrous, in the way, extra equipment to help you see at the surface.
H2O, in mask, pools in the middle of the domes.
Cheap materials, scratches easily, flimsy-skirt.
Inner fog coating lasts for a dive...maybe.
I could go on...but I'm disappointed (to put it mildly).
Maybe they should sell the technology to a mask mfg...who MIGHT do it right.
Never again.
The mask box is so gigantic, I'm surprised the airline didn't charge extra:)
If you like wasting 200bux, go for it, the lenses work...but nothing else does and you'll do a lot of work, managing this thing!
A, totally, positive review, on this thing, has to be from a mfg plant.

      Best mask I have ever used. Would not think of diving or snokling without it. I am nearsighted and it was like wearing glasses underwater. Also, correction for distortion was remarkable.
      OUTSTANDING. Everyone should try these!

      Great mask, but for me, leaks

        Comments about HydroOptix Mega 4.5 Mask:

        A great mask, but for me leaks and floods more than any mask I've used. As an instructor, I've stopped using it while teaching, until I (hopefully) find a solution.

        Someone mentioned their purge valve leaked..I'll check that...makes sense, the mask feels sealed, or may have to go with crazy glue.

        Regardless, great mask..contacts are a little hassle..but think back what early divers had to deal with...rubber suits, horse collar BCs, and big bozo masks that held a gallon of water.

          Best Uses

          Comments about HydroOptix Mega 4.5 Mask:

          I've only been able to use it once so far but I see a lot of advantages and know I am going to love it.

          First the bad because, isnt that really what you want to know? I'm not sure if it really is a bad yet but it was a bit leaky in the beginning, though most likely this was due to the course scruff on my face and it not being fully adjusted yet. Visit the web site before purchase and read the directions and specs. I also have the silver seal and it is a little stiffer than the black seal so bear in mind that they do not have the exact same sealing qualities. I will do a clean shave next time and expect to see a change.

          As for the pros: Comfortable, Great field of view with full peripheral and with everything being true to life size is where the sweet comes in! I am near sighted (-3.5)and I actually had better vision underwater with my contacts off than I do above water with them in! If you are near sighted this is definitely a better option than the old corrective lens mask... in fact; its even worth getting contacts if your eyes are perfect so you can use this mask.

          Give this mask a go!

          Comments about HydroOptix Mega 4.5 Mask:

          I mainly snorkel/spearfish. Since I am nearsighted I thought the field of view would be an advantage in hunting for fish. Field of view is amazing. The best have ever seen underwater. That said the mask didn't work for me. Any water drops collect in the center of the lenses when looking downward. They roll around and completely distract the eye. I knew it was a large volume mask but the air required to equalize it greatly reduces your breath hold time and quickly leads to it fogging no matter what I did. I still feel the greater field of view is hard to describe unless experienced ! I would say this would be a great mask for a nearsighted bottle diver that does not need to constantly equalize and trims themselves into a more vertical position once down.
