Uncle Pug once bubbled...
Well now... what do think makes a diver competent?
Do dive parameters have anything to do with whether a diver is competent to make the dive safely or not?
Well now, the short answer is *yes*, but how do YOU define safely? Safe is a relative term, oh avuncular one, and we can beat this one to death if you really like (and I suspect you do
).
"Safe" at it's most basic means to me:
-the ability to avoid or remedy all the situations that can be harmful to a diver. The BASIC list of things that can happen to a diver to hurt or kill them is short: run out of air, ascend too fast, hold your breath, stay down too long, not control buoyancy, not monitor tables or deco status, lose or damage gear, lose orientation U/W.
I think if the average diver can avoid those, have fun and not annoy Uncle Pug, we can consider them competent. Even if they don't get any style points.
Obviously, as the dive gets more complex, more attention to detail is called for, but anything that can go wrong in a cave, I suppose, is covered in my basic list.
I've seen plenty of *ugly* divers who have thousands of dives done safely. And to art.chick, I have seen more than a couple of not-so-bright dive competently!
