I was wondering if anyone could point me to where i might get tables for doing deco stops. I never go past the 130 foot limit and i breath air. When I dive I dive with my dad and we are both good on air and usally stay on the bottom until we have about 2 mins bottom time left then we head up. Since we do cut it close sometime I was wondering if someone might have tables to use for Deco stops incase of computer failure. I would like to have something to make stops just to be safe if this would happen. Thanks alot
 
Here's a bunch of links about deco. It's important that you know what the programs are doing and why, which is why posted all this stuff. At the end are a few programs. I use V-Planner.

Good luck.

You can order the U.S. Navy tables (you'll need tables 3,4, and 5) from Best Publishing - B0001-34 (3&4) $9.95; B0001-5 (5) $19.95.
You can get the NOAA air tables that include one stop decompressions from the same source - B0047-N $9.95.

Perhaps I am missing something, but am I the only person who is puzzled to see divers relying on a computer to such a degree that they "stay on the bottom until we have about 2 mins bottom time left then we head up." Two minutes of remaining bottom time seems like very small margin to protect against individual differences (compared to the generalized model programmed into the computer). Don't get me wrong, I recognize a computer as a valuable tool to expand one's diving opportunities, but a two minute margin???

And remember, computers let you make more mistakes faster than any other invention in human history, with the possible exception of handguns and tequila.
 
Hey Bill,

Yeah, I have GAP too, but I don't like nearly as well as V-Planner. V-Planner is a LOT easier to use and to manipulate. The profiles they put put out a fairly similar as I recall, with V-Planner placing more weight on the deeper stops than the shallower ones. It's been a while since I played with GAP.

Allen,

Knock dive computers and that nasty takillya all ya want, but don't be knockin' my handguns, eh! :D

Depends on the computer and how you have it set. The SUUNTO, for example, is so conservative as to be [in my opionion] almost unuseable, and that's without the several levels of additional conservatism you can crank into it. The Oceanics, on the other hand, [in my opinion] offer a better algorithm, but pushing them to two minutes routinely isn't smart.
You should never trust a dive computer to do all your planning under any circumstances - you must have a firm grasp of the tables and always apply the "is this profile reasonable" test.

Heard same thing from my local dive shop the other day regards Suunto. Word is, computer is way to conservative. :wink:
 
Keep in mind that just because a computer gets you out fast, doesn't mean you have deco'ed out right. I know someone who just got bent using an Aladin Pro Nitrox while doing a 190' warm water air dive. Don't think of hang time as a penalty.

Do you know what the circumstances surounding the DCS
accident were.

What back gas was he diving ?

had he changed the settings in his aladan.
