Xanthro:Yes, I am one of those individuals. I have no panic response. None whatsoever. I've actually been tested for this.
Actually, I was referring to the party I was responding to.
Xanthro:Familiarity with a situation reduces the risk of panic. Thus, the first dives in a new situation are always inherently more dangerous than subsquent dives.
You are foolish to embark on any dive in a new situation without being buddied with someone you trust.
"Someone you trust" does not mean "someone you're dependent upon." I never said to solo dive a new situation. I said you don't make a dive you aren't prepared for just because an instructor is there. You base your diving on YOUR preparation, not someone else's.
Your own reasoning regarding panic discounts the idea that a supervising pro will be any less prone to panic than you are, especially given the contagious nature of panic.
Again, in deciding whether to make a dive, assess your OWN preparation; don't depend on your buddy's, instructor's, or guide's preparation.
