Much panic stems from the students' own demons/baggage from the past. Incomplete comfort in the water, creatures of the deep, things that go bump in the dark
Certain things cause certain people to panic. & that everyone panics at some point for some reason. The *art* is to realize/recognize signs that you are stressed/over-tasked & know how to calm yourself down - it's different for everyone. Some people are more capable of self-awareness than others. How to judge that in your students is another matter.
I admire your program and as I'm a dork that way, I've love to sign up for one of your classes
I think panic control should be an important part of every curriculum. My favourite part of OW pool was the things-that-go-wrong scenarios (I am such a geek) and I think that the demonstration that actually running out of air was not as scary as the "thought" of running out of air helped me a lot in an incident with bad rental gear a month later.
Thlassamania, that would be one of the best arguements for smaller class size, and for the [a good] buddy system. Some students may need to get used to each sensation before moving on to the next, while others just zip through everything either because they're naturally fish, or because of some macho self-defence mechanism kicking in. A buddy on his first snorkel ever, just jumped in and kicked 40feet from the boat before realizing that he *couldn't* breath! He actually could, but felt he couldn't simply because he was not used to the shallower breathing rythmn of a snorkel. There was this embarrassing rescue that happened and he was forced to wear the orange vest the rest of the trip by the trip operator
In my pool class, some fellow students thought it would be funny to continually turn my air off to see how long it would take me to realize. My DM put a quick stop to that! As to why I didn't feel that - my pool gear was way too big and everything was bobbing up & down already
Now, I make sure I'm not anywhere near them in the water. I just don't trust them.
As for someone coming over and ripping my mask off for no reason in the middle of a perfect good dive? I'd be pissed. Probably enough to try and take their nose off with a weight once I get back on the boat....or on second thoughts, why wait?
