Throughout all my classes I have learned more than I knew before the class. Diving experience also helps create a competent diver. In my PADI AOW class, with only 13 dives, we planned for the deep dive (100 ft) completely and reviewed all required skills, instructor reminded us to do the buddy check. As we enter the water Bozo Buddy team had difficulty immediately. Bozo's buddy had to call the dive and I was assigned to desend with Bozo. Tell me how can you do a buddy check, enter the water, and not notice that your brand new, unpool tested, Cobra Dive Computer is not set to imperial measurement until you are at 100ft? He just couldn't figure out what was going on and thought he ran out of air. I had to go up with him and it was difficult to keep him calm and prevent him from bolting to the top. I forced him to stop for safety stops at 60ft and 15ft. When we surfaced we had learned that he lied about his experience (OW 3yrs. before and then only dives he had after was in the pool for AOW class). He got out the water, lit up a cig. and asked his girlfriend to go get him a drink. Training in my opinion is not going to help him until he begins to listen and value his life along with the buddy he is diving with.
