Adv Nitrox/Deco Procedures

[Potapko]

I haven't seen it mentioned yet but our TDI instructor made us do several drills that were more from a rescue class than Adv nitrox/deco. We had to do a tired diver tow for 50 ft at 100 ft depth. We also had to do an unconscious diver ascent from 100 ft IN OPEN WATER without a reference. That was fun!! We both did terrible as we did not practice that in the pool at all and he dropped it on us on our second to last training dive. He said it was part of the "new" TDI program and seemed to have it from the official web site. I told him I thought that was nuts to do in such deep water without a reference line.

We did those skill sets in all my TDI courses...but they were conducted in 30-40ffw....it's also very helpful and 'suggested' that technical divers have a min. of a recreational level Rescue program under their belt, as self/buddy rescue scenarios are part of the tech programs.

Honestly, What scuba course does not have some sort of self/buddy rescue scenario?

95% of an OW course is self/buddy rescue skills.

My TDI instructor wouldn't teach a course for me until I was a minimum of Rescue certified as well as just diving with me and getting to know each other for a bit. If you're looking for "Opportunistic Harassment" from your tech courses (which I feel is a good way to get a feel for your ability to cope with stress levels in a controlled environment) then my instructor probably isn't the one for prospective students, but at that same time I feel that he is very responsible/professional in the way that laid out his prerequisites before he would teach a class and the way he conducted his course. A few months ago I was asking him about a Trimix class and he said that he wouldn't be the best person to teach the class since he hasn't even dove Trimix in a few years.

Probably my only real gripe about the TDI program is that the standards are so broad and give individual instructors so much breathing room to teach the program in their own way that it really is a crap shoot with what you may/may not be taught in a class.

...He said, there is no right answer to that. He said, no one can tell anyone else how much risk one should take to rescue someone else. Every situation will be different, and each diver has to asses at the moment of the problem if they should take the risk or not. He said that anyone who judges another person for the decision they make at that moment has probably never been there themselves.

Another golden nugget of tech diving. There will be a time where hard decisions will have to be taken. Dive with your buddies, but be prepared to finish the dive alone.
