Jag, what did you think of the "solo diving mentality" module in the SDI course? Seems to me that this is a very important topic, but one that requires a real mentorship if the state of mind isn't there already. In other words, do you think the right mental attitude can be taught?
I'm also curious how much entanglement/extrication practice was available. Now that's something I'd like to work on. Have only been held up by kelp so far (Oregon coast), but after working on net & line cleanup in Midway atoll those things have my respect.
Four items perhaps not yet mentioned that I'd devote space to:
1. Surface survival tactics and gear, for when you lose the boat (or vice versa). Perhaps similar to being left with a buddy or a group, but it seems to me that keeping up a survival mentality would be harder without companionship.
2. Navigation, navigation, navigation.
3. Rules of thumb for gas/time/depth planning, so you can re-work the plan while underwater.
4. Practice aborting. Really aborting for the day. If you can't enjoy calling it off and doing something else, what does that say?
Fin on,
Bryan
