Jim, that's some serious shiznit. I've never done any ice diving, I just could never see the appeal. I've known a few lunatics who do it every year but I'll leave it for the rescue divers.
That AGA full face mask is the way to go. I've dove the superlites but nothing beats the AGA for comfort and performance.
Edited to add:
I'm surprised to see that you're on scuba not surface supplied air. I'd have thought that for rescue diving under the ice that you'd be diving a hose with a COM line so that you could talk to your tenders and other rescue divers.
:laugh: not sure I can speak for the 'appeal' other than a few extra percents on my paycheck! Actually, it is a blast believe it or not. it is a very trippy feeling to be crawling across the ice,
upside down, like a spider on the ceiling! And even more so when the ice is clear and free of snow, so the guys on the surface can walk with you while you crawl under them, under the ice.
The AGA masks rock... although it took some time to get used to them. I'm a 'pinch the nose to clear' kinda guy... never can clear by the swallowing or jaw wiggle. So it took some getting used to but no problems now. And as far as the supplied air and comms, well, we do have comms. The wire runs down with the tender line, but to be honest, they suck. I'm sure there are better systems out there, but since we are a city fire dept. dive team, we operate under city rules... ie. budget and bidding process. Sad when your life depends on low bid. And the supplied air is a safety issue- the lake around here are FULL of snags - trees, cars, picnic tables, you name it, it's probably in the water. We dive free bottles in case of entaglement - we can cut the tender line free, but cutting an air line is a different matter. Plus there are other issues- air quality, length restrictions, budget again, and so on. We dive with a secondary pony bottle for backup, and regularily practice rescue scenarios on our own divers getting entangled, off line, and so on.
One day I'd like to do some real ice diving, where you can actually SEE something. Our lakes we dive in are so gooey (with goose shit and other floatie type crap) we had to also get blackwater certified... it is literally pitch black when we dive. ZERO viz... you actually cannot see your hand when you put it on the lens of your mask. I'd love to go to the south pole and do some diving with the penguins, seals and such. Better than the dead bodies and muck we deal with now.
