I'm NOT most users. I prefer a purge. Different strokes for different folks. Been certified since 1992. I know what's on the market.
Already have three clear silicone purge masks. (Scuba Pro Tri-vent, SP Crystal View, Oceanmaster Perino) Looking for a HIGH QUALITY black purge mask for photography. Would like an Atomic, but no dice. Most purges fit right into the bottom of the nose pocket. They don't take up any additional space, so as a courtesy to divers that prefer purges, I wish they would offer their masks with that option.
BTW, doesn't matter how comfortable a mask feels when you try it on dry in the dive shop. You don't know if it's going to leak until you get in the water, but once it's wet and considered "used", you can't take it back for a refund...........
