So how long should they decompress to avoid the Bends?

[vicky_molokh]

Greetings, all!

I'm planning an aquatic one-shot, and I've noticed that Basic says that decompression should be slow to avoid The Bends. However, it list a value range from hours to days without any formula or even a table. How do I figure it? Overall, I find underwater rules lacking (combat etc.).

Thanks in advance to all who answer!

And with good reason. Dive tables are long, complex, and readily available from other sources to anyone sufficiently interested.

Complete with HT modifiers and other rules-specific data? ;)

Note that the tables are probably designed with safety measures, while PCs tend to go into very risky numbers.

I wouldn't "note" this at all. AFAIK, real dive tables don't attempt to coddle divers with conservative values intended to protect them from their own stupidity, and divers are expected to have the necessary diving experience to adjust the data to their own physiology as necessary.

The real dive tables do not coddle, as far as I know. However, the typical application of the paper tables is very conservative, as you assume a "square" dive profile of straight down to max depth, your entire bottom time at that depth. Dive computers take the dive tables and integrate over time, which is why computer diving is so much more cool than with the paper tables. :-)

Using a paper table and a dive lower than sixty feet or so, you'll definitely run out of no-deco time before you run out of air (unless you're hoovering). With the computer, I've never run out of no-deco time before my air tank went low, with bottom times as long as 75 minutes on one tank.

1. Molokh asks a question.
2. TBC insinuates that Molokh was too lazy to look for real data.
3. Molokh jokingly points out that said data isn't necessarily intuitive.
4. Xplo ignores the smiley and jumps all over Molokh.

Actually I remember simple tables in some 3e supplement. Wasn't there? It was a semi-rant.

But as for the hint to include smileys when I make joke, now I see that the hint was useless. I'll search the fora for the person who made that suggestion and sue them!

Thanks for the info on diving computers. That's a neat thing to know, as the question is related to a retrotechy TL9 adventure (computers are large, but a dedicated diving calculator is ok).

I believe 3e High Tech or Special Ops had some stuff.

That or one of the Compendia...
