Really what is the point of teaching a course if you don't train your student to max limits?That is not what I said at all. The previous sentence was referring to TDI standards.
What I did say was:
“There is not really a necessity to do a deep air dive to 180 feet during the course.”
i would definitely not endanger a student by going to 180 feet on air, just because I could under that standard.
I also never said that I would let the student figure it out on there own. I do not know where you are getting this from, certainly not me.
Doing it shallower where two decompression gasses are not needed doesn't make sense to me.What I am gathering from this discussion is that the true value of the course is teaching the use of the second deco gas, and in teaching that second deco gas, you don't have to go to 180 feet. In other words, the emphasis of the course is misplaced by talking about depth and extended range.
If the course is done shallower and focuses on using two decompression gases, then it make a lot more sense.
Just take normoxic trimix down to 60 meters/200 feet, learn to use two decompression gasses and be done with it.
The sooner deep air stops being taught, the better.
