When does "Gas Management" get taught?

[StSomewhere]

Exactly. There is an Essentials DVD that goes with the Essentials course. They also have Intro to Tech (ala DIR-F) and soon-to-be-released Tech Diver DVDs. The level that RB is covered in the Essentials DVD is more along the lines that you suggested for your OW class. Good luck!

The DVD is probably a lot easier than digging it all out of the threads here... but SB (and the .pdfs you linked) is free. I like free.

I like free too, but the Essentials DVD is only $20. And its the best $20 I spent on any educational diving video.

The guys at 5thD-X did exactly what you are planning to do. In Essentials, they introduce the idea of rock bottom and usable air. And leave the students with a basic chart of tanks vs depth vs rock bottom. And then in the next class (post Essentials), they will actually go over the calculations in detail.
