I got certified in Australia this summer, but am about to go on my first CA dive in a few days. I have a quick question regarding surfacing procedures;
In Queensland, it is apparently ILLEGAL to surface with less than 50 bar in the tank (an AL80 capacitiy is typically 200 bar, so 50 is a good chunk of air), and I was taught to start heading up with about 70. How does this equait to PSI? I know that the same AL80's hold 3000 psi, so should I be surfaced with 1/4 of that (750 psi) or is that just some QLD specific regulation rather than a guideline?
Thanks, and if there has been a thread about this in the past, please advise; I didn't run across any.
