Jim, from your previous postings i get the impression that you take training/certifying divers seriously. I can assure you that we practiced no skills on my aow dives, and the classroom was nothing more than a slideshow of the book. We did 3 drift dives on a reef that was impossible to get lost on (for navigation) one time my wife held the dive buoy and another time I held it... I was told this meant we "led" the dive and that was required for the cert. The deep dive was in 6-8 ft seas and was 115'. I did learn a lot from that dive... I learned what it is like to have co2 buildup due to exertion that leads to a feeling of unease... I learned that it is better to get separated from the group than try to keep up and exert yourself... Neither of these were learned due to being in the class, just from being on the dive. (I learned about co2 from SB after the fact). I can assure you that just because the agency is naui that doesn't mean that the instructor is a good one. (I am nitrox certified from naui too and that class was worse... The instructor couldn't explain some things and my wife and I actually defined a couple of words for him that were in the presentation...not to mention he skipped some slides). These experiences don't bother me that much, but it did teach me to be more selective when picking instructors for rescue and beyond.
