Davey Diverson once bubbled...
You were abundantly clear. You said
"If my students are crashing the bottom in the pool they don't go to OW. If they can't do simple skills off the bottom they don't go to OW."
And he said:
"It took me about 40 dives just be to "decent" at buoyancy control."
Seems clear to me, unless you meant something else.
Well it doesn't take my students 40 dives to get good enough to avoid silting. I would think he would have enjoyed his OW dives much more and got more out of them.
I'm not advocating anything. I want to know how this guy feels about your stated passing requirements.
They're not my passing requirements. It's all in the training standards not to mention common sense.
Well, here is where we disagree. BC is a skill, and it's mastered through practice, not instruction. Some folks nail it right away, others take 40 dives or so. In fact, my experience is that the latter, to some degree or another, is the norm.
It's like saying you can teach someone to hit a major league fastball. You might be able to teach swing, grip, and stance, but getting wood on Randy Johnson takes time.
Since you're convinced that OW classes will destroy the vis, I'm not sure you really know what it takes to learn buoyancy control. You're right, it does take practice. We practice before we go to OW. It may not require instruction as few things do but it sure shortens the learning curve. I prove it with every class I teach.
To use your baseball analogy, most classes apparantly aren't teaching the swing, grip and stance. Some of us do and with a few hours practice students are good enough to avoid silting out the dive site.
