ASL is a little more complex than that. If you are familor w/ ASL and your diving buddy is too, then you will have no problem with communication, as long as you can see each other. ASL or American Sign Language is the prefered language of the deaf community. The signs that are taught in Scuba lessons and consequently used by divers isn't ASL, it's what is called "home signs" or signs used by a specific group, generally the signs are made up by the group (in this case the diving community) and used for the most common phrases like acending, decending, out of air, etc. I've found that the signs used in Scuba are different than their true signs in ASL, so although it may seem like the same thing... ASL and scuba signing are quite different.
I've been fluent in ASL for a few years and really love to dive with those that are also fluent, it makes diving that much safer and more enjoyable.
So to answer the original question, if you and your buddy would like limitless communication abilities, take a ASL class or two and you will love it.
