robinzon:my goodness so much misinformation from people who never dived the mask.
Ocean Reef performs fine and diving is much easier than without one as long as you know how to clear/equalize it.... most people don't know how to use one and hence the resulting opinions. It works fine with any reg, I have used it with my mk25 and mk2
As a matter of fact I have spoken to people who dived in the Arctic w/ Interspiro nad hated it vs. Ocean Reef (spec. they did not like the AGA nose piece). At any rate I am also planing on purchasing AGA and Drager for comparison and for CCR use.
Which misinformation are you referring to?
