Hmmm.... To give a diver a reasonable estimate of an NDL with credit for a multi-level profile on-the-fly where you may not know before-hand the profile that the dive will present, without doing all the work of keeping track of average depth and calculating an estimated NDL in your head...

To our casual readers and lurkers: Take note that it seems the only folks disdaining the use of computers here (completely aside from reliability issues) are talking about them in the context of technical diving: deco, deep, trimix, gas switches, etc. BTW, the OP (me) was really asking a...

Good, Kev. Good to see your face and tongue here. I think I'll call down there tomorrow morning and book for this weekend. I'll be the one with a computer. Or tables. Or both. Or seat-of-my-wetsuit. I don't know. They're all good.

DIR-A, Charlie is (as always) right on target here. The 60 minute compartment for the DSAT and the 120 minute compartment for the Navy tables are used to calculate Surface Interval credit, not repetitive dives. Computers continue to track all of their compartments during the surface interval the...

And lack of battieries help you understand deco theory how? Read the original question, K.

Rather than hijack this thread further, I've started a new thread. Rick, your answer is pertinent to that thread. I hope you'll post in that also.

Quoted from another thread: Ignoring issues of reliability, just considering understanding of decompression, why do so many people repeatedly say that learning to use the deco tables in OW is preferable to learning to use a computer?

Why does anyone think that knowing how to read a table provides an understanding of "what's going on"? How do the numbers on the tables better represent the formulae and algorithms used to calculate decompression than the display of a dive computer or the output of a deco program? Would learning...

Where do these ideas come from?

Be sure to go for the newly updated 2nd edition of Deeper into Diving, available here. It is not yet available on Amazon. (They still have the older 1st edition listed.)

Kris, Since you are watching this thread carefully, maybe it is a good place for a wish list, also. Third-party developers take note. I would like to see some sort of tracking of tissue compartment loading using a Haldane/Buhlmann model in the desktop software. It would be interesting to...

For a partial answer, quoting UP from this post: (As always, be sure to consider the context of the quote. Also, note that this is from 2003. He may have changed his procedures.)

Walter, would you define/contrast live boating vs. drift diving for me?

On our South Florida drift dives, the DM is towing (or, more accurately, being towed by) the float ball, which is often moving faster than the divers due to the stronger current at the surface than at depth. It's sometimes hard work for them to slow down. The DM is also sometimes in so much...

I always liked his attitude, advice, and point of view. Condolences to everyone on SB. We've lost a great one.

I've replaced the stock band on my Cressi Archimede with 1" wide elastic (purchased at WallyWorld). Just remove the watch style pins, take them out of the band, replace them into the computer case, and thread the elastic under the pins. I did two bands, one inside the other, for redundancy. I...

Nice write-up, Barb. Can't wait to get back there.

I think in the discussion of EAN on Air tables this statement implies an extremely important point. Per much research, nitrogen loading does not appear to be the only factor in DCS. Always keep in mind very influential factors such as hydration, ascent profile, exercise during and after the...

If they don't have any, maybe your brother could send some along with your reg and computer (which you probably won't have in time for your dives next weekend, since he hasn't sent them yet). But you can probably use the wetsuit with the kneepad flopping around a bit. It will make you look like...
