I'm asking this question as a currently recreational level diver that has rarely exceeded 100 foot depths (planned not accidental). My reason for the inquiry is purely academic at this time and prompted by the reading of an article who's URL was posted in another thread. Someday, I believe my curiosity and drive toward the unknown will lead me to technical diving, but I'm not in a hurry. I figure I'll get there when I get there.
Let me be clear about one thing. I am not asking the question, so that I can go out and start experimenting on my own without proper training. I believe that one should be properly trained for any diving that exceeds one's current level of training and experience. The only time this changes is when you are a pioneer doing something no one has ever done before and have already gone through all other levels of training available in your endeavor. I probably won't have to worry about that for a while.
This is the URL that prompted my question and it was interesting to read from a historical perspective:

The following mixtures were mentioned in the article, but I'm also interested in knowing if there are others.
Air
Nitrox (Does this differ from EANx?)
Trimix
Heliox
Hydrox (Isn't that also the name of a midwestern cookie or cracker?)
Hydreliox
Q: What are the currently accepted depth "ranges" for air and each of the mixed gases by today's standards? :06:
What I'm looking for in otherwords is, "air would be used from zero to no more than 'x' feet deep, heliox would be used from 'x' feet deep to no more than 'y' feet deep", etc. Of course, the reasons "why" would also be helpful.
Thanks for your help in starting to understand this stuff.
