I have been diving for 14 years and am always searching for a GOOD fitting mask. You should see my collection. I know I got a funny shaped head. :cwmddd: The best so far is the Dacor Stryker TL, single window,frameless with purge, moderate volume. Of course they are not made anymore. I try on masks everyplace I can. All the local shops, Our World Underwater, Dema. I haven't found a suitable replacement yet. Not even Atomic frameless, volume to low, contact with my brow. Anyone have a suggestion, besides go suck a lemon (aka S.O.L.) Come on ScubaBoard ! I beleive, I beleive !
