Those must be quite the classes, and I'm sure very expensive.sorry, but there are far to many instructors that are not worth any salt...and even for the good ones, 3 classes will not put the student through every conceivable type of stress (emphasis mine) they need to deal with.
I guess I see training a different way, I'm looking for tools to handle multiple situations, not verbatim instructions on each. If you need training to handle EVERY conceivable issue, feel free to pay for all of that fluff. I'll refrain my last question... following that PADI model, what different training on a rebreather would you learn between courses like Tec40 through Tec Trimix and deeper? I can see different planning and maybe bottle management, but again, all that can be covered in 3 classes.
