caseybird:OK, we have our divers, 70 miles offshore, lost on a wreck in poor viz and current, in the shipping lanes in fog, and these fricking guys don't have redundant air? Rock bottom calcs are not going to solve thier problems.
Leave the bottom at 800 psi. That's good advice.
Ummm, Yes?
What's your point?
The best I can come up with from your example is that recreational divers should never dive beyond their limits. And let's face it, the divers in your example are already dead from a long surface interval, lost in the fog, drifting into shipping lanes, and hoping the Coast Guard will find them before they die from the elements. That's of course if they made it back to the surface alive in the first place.
But in your defense, having not stated a depth in your example, let's say the depth was only 20', they surfaced close to the boat, and were saved from certain doom. Yay Team!
Any landing you can walk away from is a good landing in my book.
