CATTRAX,
Welcome aboard! You'll find a lot of information on equipment, dive medicine, decompression theory and practice, and a lot of good people to make connections to dive with on this Board.
You'll also find that, unlike the Rec.Scuba Board, while we do have our little tiffs, the standard here is polite behavior and educated discussion.
In the medical section we have quite a few medical doctors and our pet rogue dentist, Dr. Larry Stein, who are divers. You'll find they can, at times be quite helpful.
In our decompression section, you will find such people as Doc Deco, who works for NASA, Dr. Sawatsky, who works for DRDC (ex-DCIEM, Canada), and Dr. Bruce Wienke, of Los Alamos National Labs, as well as some very educated and dedicated amateurs.
We even have a small section with some highly dedicated and knowlegeable rebreather divers.
Again, welcome aboard. Happy and safe diving to you!
