Yo, Adriaan, 

patience is the # 1 rule when it comes do technical diving. Sometimes it
takes about 24 hours for someone to get to your questions here --- we are
out diving ya know. 

Heliox is not a viable option for open circuit scuba -- the decompressions
just get too long, and the chill factor is too high. Hence it must be
buffered with nitrogen ie: Trimix. 

But lets set that aside for a moment. 

So ya wanna dive heliox ..... its used for commercial and special military
operations almost exclusively.  You can get trained for Heliox diving from
most any commercial diving vocational school. You will have to go thru the
steps of being a tender, air diver, etc, before they will let you even
sniff heliox. Oh and expect to pay about 12-24 grand US for the appropriate
commercial diver training. 

There are books --- that have all the heliox data in them -- US Navy Mixed
Gas Diving Manual, NOAA Diving Manual, COMEX diving manual etc. 

You will not find heliox or trimix tables online -- mostly they are
proprietary and kept away from the untrained in a feeble attempt to keep
them (the divers) alive.  Its a bit more complicated than filling a tank
with balloon gas and reading a table. 

hope this helps you ---- 

Do it Right or Don't Do it At All
