Yeah, that's what I don't get, actually. I was under the impression that just AN didn't cover mandatory deco dives, but maybe I'm wrong about that. Or are they riding the NDL so close that it's technically a rec dive but one more minute puts you into mandatory deco?
It doesn’t, per the TDI website (below). What people will do though is combine the two courses to get both certs.
The TDI Decompression Procedures Course combined with the TDI Advanced Nitrox course form the foundation of all other technical courses.
~116’ is toward the upper end of recreational limits. Assuming that you’re conservative with EAN30 @ 1.4...it doesn’t leave you with a whole lot of bottom time. ~16 min per the planner on my computer.
To make it worthwhile to leave the dock and gear up, I would think that most that would want to dive the B-29 are going to want to stick around on the bottom long enough that you’re going to accrue a deco obligation. Just my AOW newb two cents though.
