Good mask. To fix the regulator is a bit tricky, and it should have different sizes for different face sizes. Otherwise its a good product.

  • nahit:

    How do I get a regulator that in this mask Have gerekir.Regulatör photo attached.

    Darrick  (Certified Scuba Instructor at

    Hello Nahit, consider the mask as the mouthpiece. It would attach to the regulator as you would attach the mouthpiece to the regulator.

  • conner:

    do you need a air resperator and kan you hook it to a hookah air compressor

    Bill  (Certified Scuba Instructor at

    This mask uses a separate primary second stage regulator. It will work with a hookah or scuba regulator.

  • David:

    Can this mask be equipped for optical lense for us who wear glasses or can be fitted with corrected lenses?

    Bill  (Certified Scuba Instructor at

    We do not carry lens for this mask.

  • chuck:

    I have a hookah with the oceanic delta 4 regulator. Will this regulator work with the first full face scuba dive mask #M37BS ? Reg,# CEO120EN250 And 00424804

    Darrick  (Certified Scuba Instructor at

    Hello Chuck, for this to work with your current equipment you would need to remove the mouthpiece off your regulator and attach the mask to the regulator and you will be all set to use your full face mask.

  • dar:

    we have recently started snorkeling and i was wondering if the mouthpiece will fit/can be adapted to this mask... i have tried the regular mouthpiece but continue to gag when in my mouth.

    Bill  (Certified Scuba Instructor at

    This should work with a snorkel.

  • wendy:

    Hi, I never went scuba diving before because I cannot breathe properly thru a mouthpiece and I fear that I may freak out underwater if I cant breathe. I dont want to miss out on these experiences. This mask looks like itll solve my problem, will it fit most rental gear at scuba diving sites worldwide?

    Bill  (Certified Scuba Instructor at

    This will most standard second stage regulators.

  • nahit:

    Hi I would like take this mask, but you kind of need the regulatör.

    Bob  (Certified Scuba Instructor at

    Yes you do.

  • MIKE:

    does water get in the mask and if it does how do you clear the water out of the mask?

    Arthur  (Certified Scuba Instructor at

    When you exhale it would exit out the regulator.

  • Alii:

    Hello, I just received these mask yesterday. My face sits far from the inside of the mask, is this normal? It seems like i will get tunnel vision because im so far from the lense. Also my nose dosent reach the front to well. I have to treat the bottom nose peice as a rubber nose blocker to equalize.

    Bob  (Certified Scuba Instructor at

    This is not unusual. As with any mask, the overall fit will be different on each user based on their dimensions.

  • Alii:

    Can you explain how to equalize using this mask? I get jaw fatigue real easy followed by a bad headache. I was looking into this mask because of the price and the review are awesome. wish someone youtube a video using this mask...Maybe I will.

    Arthur  (Certified Scuba Instructor at

    Hello, it has a rubber nose piece to equalizing would be the same as a normal mask.
