The fundamental implication here is that the students you see in the video are going to translate into the poor divers who frustrate several members of this thread in the caves of North Florida. But I think the point has been made pretty clearly that we left the course with a good understanding of what to improve and none of us have any intention of being those people. So on a practical level, what did Chatterton fail at in his attempt to produce good divers? Who's to say he didn't look at us as divers and make a conscious choice about what level is wisest to hold us to at this moment with all the context required to understand what types of divers we will become?
Do you believe I am wrong about our ability to improve and we will never learn what you describe? Or do you believe it is not possible for someone like Chatterton to use judgement in that way? Please remember that a certification card (particularly the Adv Wreck one) is a token, it's not the goal of diving or learning. We all know people who hold many cards but we wouldn't want to dive with, and people who earn cert cards and then never learn a thing again. One of the great things I learned from my time with Chatterton was it's possible to spend fifty years diving, learning every day. I believe we should be talking about if an instructor is good at making better lifelong divers, not if any particular training dive someone did was perfect.
Amen!
