"AOW is a pretty good training course....."
Not usually, although I'm sure there are exceptions.
Due to the "freedom to teach" concept embraced by NAUI and SSI, some instructors have the freedom to tailor their courses to the students' specific needs. This is what I do.
I think of an AOW course as a progression from basic O/W and as a preparatory course for basic rescue.
As a progression from basic O/W, I like to transition the divers to diving from 50 ft or shallower, which is what I taught them in their basic O/W course, to depths of 50 to 100 ft now. Therefore deeper diving is a part of my AOW course, and I work-in BRW's RGBM air and nitrox NDL tables for deeper diving.
I also give them nitrox instruction and a nitrox C-card together with their AOW C-card, since diving in the 50 to 100 ft range is a nitrox range, in my opinion.
We also review the dive tables, and dive computer rules, to make sure they are diving their deepest dives first, and are allowing a sufficient surface interval between dives. We factor in SCR-RMVs as well and compare them to NDLs for deeper dives.
Then I like to introduce gear maintenance and field repairs. We take hoses off and put them back onto the 1st stage and tighten them. Then we check them to make sure they are tight before going diving. We tighten port plugs as well. I show them my field tool kit for scuba.
As a preparatory course for basic rescue, I like to cover advanced navigation topics such as navigation squares, search patterns, recoveries with lift bags and spools, and distance measurement by fin cycles. Then we all go out and do some night diving to put our navigation skills to work, as well as some search and recovery diving during the daytime.
Depth, nitrox, gear, nav, search, and recovery are the components that I emphasize in AOW. If a student then wants more, we can also do more.
