Getting back into SCUBA: Where to start?

[TMHeimer]

Yeah, I don't disagree with you. I did the same as you learning the computer but going from square profiles to varied profiles it would have been helpful for someone to explain how the computer is going to react. I mean, it was kind of surprising to me when I started using the computer to REALLY see how NDL was changing with depth and that I could dive to 80ft and still get an hour dive out of a tank. A refresher in a pool doesn't do much - I mean, its a pool.

I too was surprised when first using a computer how my bottom time increased a lot after you start ascending. I did my speech on the eRDPml on the "question" thread today. The computer does for you what the eRDPml wants to do for multi-level dives but really can't.
