Questions and Answers for H2O Alpha 4 Purge Mask:

  • Max:

    I am looking for a mask that wont leak but is reasonably priced ($75). I have a rather large face and weigh 240. What would you recommend? This will be used for both snorkling and scuba.

    Darrick  (Certified Scuba Instructor at Scuba.com):

    Hello Max, the mask that I would suggest for you is the H2O Tri-View Frameless Scuba Dive Mask web link: http://www.scuba.com/scuba-gear-32/027449/H2O-Tri-View-Frameless-Mask.html.

  • denny:

    I currently wear a prescription mask that has a clear area in the bottom of the lens to aid in reading gauges, etc. Do these lens cover the full inner area of the mask or can they leave the bottom area open. The other question would be on returns on a custom item like this. Thanks!

  • TC:

    When you buy corrective lenses for these masks, who installs them? Does the mask come with corrective lenses installed?

    Chance  (Certified Scuba Instructor at Scuba.com):

    We have divers assemble the lenses before we ship them. The mask will come with the lenses installed.
