Actually I mentioned that they were no Technical dives, so no Trimix. With enriched air you can't go to that depth anyway.
With regular compressed Air are dives down to 50 meters no problem. (no PADI diving). Sure, they will end as decompression-dives. I would not do that with a single "regular" 80 cuft tank. With a 100 cuft. maybe if the conditions are right.
As I know the "old" Atlantis regulations I am just wondering, I have actually some more thing. Emails and posts from public boards...
I just can't agree if recreational divers who pay alot of money are taken in dangerous situations.
