Thanks Brian- I think that the course has some significant benefits over Advanced Nitrox- it gives people options about picking better gases for intermediate depths and incorporates the basic skills required to accomplish dives to these depths. A reduction in the level of Narcosis at these depths is a positive benefit over diving weak nitrox mixes in the 35-45m range.
On the Triox course we spend a lot of time discussing gas requirements and the minimum levels of reserve are determined by IANTD. Instructors do have the ability to increase these reserves to reflect the planned dive and student capabilities.
When GUE finalise their own Triox course then I am sure a number of fundies level divers would see that as the next logical step prior to the jump to Tech 1.
