While I would teach an AOW course right after OW if I felt the student was prepared and had a good grasp of the basics, I prefer that my students would go and just dive for 10 or 15 dives before doing so. They are more than welcome to come along on any weekends I'm diving within their limits or doing checkouts with others. And then I'd rather they do the SEI Advanced Plus which is 10 dives and includes classroom sessions dealing with gas management, navigation, limited visibility procedures,( before doing night or low vis dives) and search and recovery options. All totalled it would involve a minimum of 6 hours more classroom time in addition to the dives. Of which with me 3 would be deep, 3 navigation, 2 search and recovery, and 2 low vis/night. We'd cover altitude procedures and planning as well since the dives locally many times involve diving at altitude(3500ft). On all dives we'd also work on buoyancy and trim, non silting techniques, and buddy communication and skills. As well as going over a few basics like mask off and on, but while maintaining depth at 70 feet or deeper. Conditions permitting I'd also like to see them do an air share at 60-70 feet.
