DIR Answer Required

[Cacia]

Catherine,
Jeff gave the best answer Max depth is X; Max time is Y for that depth or turn pressure Z, all discussed by the team before the dive. When Y or Z is reached it's time to ascend. Perhaps when there is another SB lunch here on the island I'll stop by and you can beat me up.

I can deal with your answer.

Sigh I have taken a DIRF class (I even passed) and I understand how I would think through the problem. I was asking how the computer folks would think through the problem given their current training.

Lets see how someone else answers shal we eyebrow

Grrrr... no kidding really.... oh well so much for asking the folks a trick question.

Hey Ed ... nice to see you in here. When and where did you do Fundies ??

Hey guys ... ease up. Ed's a good guy, and one of the smartest "newbie" divers I ever dived with. He knew more at 12 dives than I did at 120.

My hoses re-routed where?

Hey sorry for being dense but I don't understand how you guys execute ad-hoc dives with a computer. Take the following situation:

You're at 70fsw with 1200psi in your AL80 and your computer says you have 25 minutes remaining on your NDL. You see a really cool <whatever> at about 100fsw. Assuming it will only take a minute to descend how do you figure out how much time you can safely spend at that depth.

Would someone who uses a computer regularly explain their thought process to me? Do you start the descent and just keep a close eye on your NDL and SPG?

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.

on-float, never mind. (just looks like your hoses are a little drapey...you know entanglement hazard) I was kidding a little, Sir. BTW, where is that hose going in your left hand?? It almost appears your long hose is not tucked.
