TDI isn't much better by the depth numbers, than DSAT. Their entry level deco course (no mix allowed) is 150ft, and they argue their deep air course is 180 or so (Extended range). I think Brett made that argument a few decades ago when it might have had a hint of realism...........good morning cowboys, it 2007, time to wakey wakey, or take up golf.MikeFerrara:I think most of the tech agencies provide ways to avoid deep diving on air these days. With IANTD, you can combine normoxic trimix with the technical diver course. GUE doesn't mess with the deep air thing at all. I'm not sure about TDI. Here comes DSAT with a sparkeling new course with no option for helium prior to doing the course to 165. It looks like flat out insanity to me. I guess some instructors are conducting these courses without hitting the max allowable depths. Since deep diving is the subject, I think that's even more rediculous.
I think allowing the option is one thing but making it a requirement is another. Personally, I wouldn't even bother with an agency that doesn't get it yet.
They also argue that this doesn't mean that instuctors are required to push their students to the max depth. Like you, I think this is a bull$hit argument devoid of common sense at this level of the game. They're arguing one thing, but clearly opening the door for you to do the other. Whatever, it's insured. :shakehead
This is a concern for a lot of instructor with TDI as I understand, and a lot really want TDI to get with the program and start offering the option to do what is right and just skip the whole air nonsense, like GUE does, and also is what NAUI allows for.
TDI brass on the other hand is not really in bed with the idea.:mooner:
