Tell me what issues you think a diver would have running normoxic trimix as opposed to straight air or nitrox for any of the actual dives for AN/DP..
Consequences.
Air is far more forgiving of errors than helium. That's why helium was traditionally withheld until later stages, where the tech diver had accumulated more experience and made many of their mistakes.
If we can assume that training standards are exemplary... and that qualifying divers are mistake-proof straight out of a few days training, then I see no negative issues with introducing helium to the mix.
Should we assume that training standards are exemplary? LOL
I am hoping to start an/dp soon and was wondering if intro to tec was required or if it was up to the instructor. Thanks neil
Required no, but might be recommended by your instructor. If you're just over the minimum req's and have little/no deep or doubles experience the intro to tech course is a good foundation for the AN/DP course.I am hoping to start an/dp soon and was wondering if intro to tec was required or if it was up to the instructor.

You can do Intro to Tech in single tank - it was one of the courses my wife and I were looking at along with Essentials, Fundies, etc when we were just starting off diving more regularly.Are you required to take Intro to Tech in doubles (SM or BM)?

Also, if you do decide to do AN/DP/H, the instructor at that time may just need to see you in the water with the doubles setup (BM or SM) and that would be it since ITT isn't a pre-req for any courses higher up the ladder.
