I just finished teaching an AOW class this past week-end. It was my biggest AOW class ever ... 4 students. But I had another instructor who regularly helps me with classes, so it was a 2:1 ratio. All of my students had between 20 to 50 dives prior to class, and had gone through a skills workshop with me prior to the class. We did not do 5 guided dives. In my class there are six scheduled dives ... and we'll do more than that if needed to achieve the class objectives. There are no "electives" ... each dive focuses on specific skills. All dives are conducted while hovering ... kneeling on the bottom is not allowed. Ascents up a line are done in a controlled manner, with stops that are made while hovering ... grabbing the line is not allowed. All dives emphasize good buoyancy control and trim ... you have to do the navigation course twice, so if you silt it out the first time around, you're going to have to live with the consequences when you go back through it the second time. This teaches the importance of good finning techniques ... which we also cover. Buddy skills are emphasized ... positioning and communication are essential for some of the exercises you'll be doing. Gas management isn't just taught, you have to calculate how much gas you expect to need for the deep dive, based on measurements we make during the class. You're taught how to use a lift bag, reel, and how to deploy a surface marker buoy from depth. Navigation isn't "out and back" ... you're sent on a complex route at the end of which you're expected to find your way back to the buoy line ... and you're shown beforehand how to do it. And for the final dive, you navigate a pattern while swimming midwater ... at a constant depth ... where you can't see the bottom. One dive buddy gets the compass, the other gets the depth gauge and bottom timer. You have to work together to complete the course ... all while holding a 20-foot depth. It seems difficult at first, but it teaches you how to maintain your buoyancy and awareness while focusing on a specific task ... a skill that's useful in many ways while diving.
Quite a lot can be achieved in an AOW class ... you just have to take it with an instructor who's not just looking to sell you a few guided dives ...
