Is this indeed the case? For me TDI made it simpler and cheaper to get the deep air/O2 deco = certification than IANTD or ANDI. I prefer more content and less number = of training courses.

As such tri-mix is saved for best, and most people = can't afford it. Hence the popularity of Deep Air. Guy. ------ =_NextPart_000_01BB904A.6055B570--
