Absolutely dripping with sarcasm. Certification means nothing. I've seen people with advanced certifications running low on gas because the damned fools think they need not closely monitor their SPGs because they know with exactitude what their air consumption is . It's almost a 'look ma no hands' arrogance. Just because a very experienced diver can predict what their remaining gas is 99 times out of a hundred does not mean they can ignore their gas pressure gauge for extended periods. Then there are the idiots who lose track of time and place while trying to compose the perfect shot.Just curious,
I can't really tell are you being sarcastic or serious? I've seen DM's and instructors suck down air like a jet intake. I really hope you are just making a point because that is some flawed logic if not. Being certified doesn't mean ****.
But why go on. Sorry if the sarcasm, and a certain level of anger, was not as evident I intended.
