It depends on the Adventure dives that you choose while pursuing the certification. They each have their own requirements for you to master. The navigation adventure dive, for example, has you demonstrate neutral bouyancy, determining distance traveled, navigating in naturally, using a compass, navigating using a compass in a straight line and a square.I was currious for those of you that have your AOW cert what skills you had to demo during the check out dives for the course.
The deep dive has less formal requirements, including, descending properly, comparing color changes at depth and guage readings, performing a slow ascent and a safety stop, using guages.
