HI all,
When I was in my OW class back in '94 the course director was an old Navy diver w/ about a million dives. He told me that he knew an individual that had done an emergency ascent (swimming to the surface at safe rate, exhaling all the way) from MORE THAN 90'. He seemed like a good guy, but this is a second-hand story from someone I don't really know.
On this board I've read that it's not practical to expect to be able to do an emergency ascent from more than 40', and 90' seems like an awfully long way.
I've only tried it from 15', for training, and never had to rely on this method, praise God. What's the deepest that anyone has actually done an emergency ascent from (sucessfully)?
Yes I know about buddy system, back-up regulators, etc, etc, so let's not re-hash all that, 'kay?
