Yeah, I know I looked up at the camera and my light cord dangled. ( am I allowed to say that??)

We have to kick you out of the club for that bit of strokery. Rule 6 violation

This is how I dove before I became DIR, and pretty much what most recreational agencies "teach," or at least let students come away with. Your guess is correct. Watch your NDL time on your comp and your SPG. Turn in time to get on the boat with around 500-750 psi. hope to God your buddy doesn't need air. Go straight to your safety stop at 30 Ft/min, hope you have enough air to last. Stupid? Absolutely. This is why it's not DIR.

So until you were a DIR diver you were a "stupid" diver?

No no, but the idea of relying on the computer to tell you everything you need to know while eyeballing your SPG with no consumption rate calculation isn't real smart, in retrospect. One good miscalculation and I'd have been SOL.

He has some good ideas about non-computer diving.

My DIR-F instructor was fine with computers as long as you could leave them in gauge mode... permanently. I do that now because I prefered his alternative for rec diving, which is basically to use average depth with my tables, DIR ascents and not to worry about surface intervals. He wouldn't tell me how to do deco on the fly though and suggested GUE tech 1 instead.

Based on my discussions on these boards though I think different instructors teach different alternatives to computer diving, if at all. (edit: computer, not non-computer)

Patton said that? ... that's in poor taste.

so, if you are leaving them in "gauge mode" permanently, are they not computers?

Its still a plan. Might not be the best one, but its not the worst either. It at least implies some level of awareness of what is going on.

I do agree that you have to know your own SAC in a given situation and not rely on the consumption rate your computer is displaying. That goes to situational awareness.
