Try one out at at a scuba show, then you'll see why anyone with normal vision would even contemplate putting contacts in just to be able to use it , It's that
different from a normal mask
I too was reluctant to spend that kind of money on a mask that I had not tried, even though my eyes would be a match for the mask at -5 ... I talked to Jon & Terri at the Long Beach Scuba Show and they both were very knowledgeable, accommodating, and nice ... after talking to them and trying the mask, I got one, at a very good price (actually, I just
had to get one after trying it)
I'll be trying it out this week diving to the Yukon
Heh, actually putting contacts in to use a mask is not so new .. is what I've had to do since starting to dive ..
EDIT: have you tried it? ...
