Best Answer

There are very few true altitude tables. Most tables use a conversion table so a sea level table can be used at altitude. In essence you treat your dive as being deeper than it really is - which has the effect of decreasing the no-stop time limits. Time limits need to be decreased because you are surfacing to a lesser atmospheric pressure - which is analogous to flying after a dive.

Do you have to be a certain weight or body type to be a scuba diver?

No, you don't need a certain body type to scuba dive. Because you use flippers to SCUBA dive, you can be a very lousy swimmer and learn to SCUBA dive. You may look stupid with a very tight wet suit during scuba diving, but you can dive. When I got certified, I learned that you have a very slightly higher chance of the Bends during scuba diving, but this is a small percentage. The pros of scuba diving outweigh the cons.
