Angie S once bubbled...
Then, when the *new* textbook came out toward the end of our class, there was barely a mention in it about SAC rate, and certainly nothing about a time calculator. I am so glad that I got the "old" materials and the information about planning air consumption. Is the assumption now that everyone should have a dive computer? I haven't saved enough money yet for my own BC and regs, much less a computer. So I guess I'll be the slow one on the boat, sitting there with my antique planning slate!
Have a good weekend, everyone!

I'm an instructor for two agencies and I don't know what assumptions their making. Not all dive computers are air integrated so I don't think that's it. I think they just hope your shallow enough that the ascent doesn't use a significant amount of gas. Maybe they assume you'll be diving under supervision and someone else (DM?) will look out for you. But guess what...PADI dive masters aren't taught squat about gas management either. IANTD goes into it a little further at the OW level. Like many other things they seem to think OW is too soon to teach it but they don't include it in the other classes either. Like trim, most agencies don't even mention it in the OW course. Funny though it's also missing from the AOW materials and rescue and DM and the Instructor development course. To be honest I have given up trying to make sense of the logic and do what I think I should (in compliance of standards of course).
