So often it's a matter of ego. Who has the "hardest" agency or who is the most "old school". Personally, I reject the old school mentality. They are indeed legends in their own minds, but aside from that, the sport seems to be enjoying fewer injuries per capita and not more. You don't need to be a Navy Seal to dive safely. Not even close!
I would daresay, that trim and neutral buoyancy are better taught in the current classes than those ten years ago and especially those 20 or 30 years ago. Why? First, there was little emphasis on reef protection back then. Second, people are able to get better information about their diving via the internet. You old farts never had the luxury of being able to do research about this sport so quickly and efficiently before.
Knowledge was often given on a "need to know" basis. You were not able to gain new knowledge until your drillmaster, er instructor, gave you access. Dive training was often on par with some kind of "boot camp" mentality that gave the instructor ultimate power.
The paradigm has changed. Students no longer need or want the "Sage on the Stage" mentality proffered by many "old school" instructors. They are tired of inefficient and backward teaching methods that extend the learning curve ad nauseum just so you can smugly do things the way you have always done them. You didn't invent Scuba, stop acting like you have some sort of lock on it's secrets!
I would suggest to most students looking to learn to dive today: Take TWO courses. Do your academics on line, in the comfort of your home or office.
www.tdisdi.com,
www.evodive.com as well as the site who seems to have started it all:
www.scuba-training.net are wonderful places to begin your knowledge acquisition.
Then find an instructor who lives to teach! Don't look for the guy or gal who has become dour about the state of dive training. Rather look for the instructor who just can't wait to get YOU into the water to learn skills. If they have an inflated view of themselves, I would walk, as Scuba will be more about them than about you. Scuba is a FUN sport... find some one who will make and keep it fun.
Flame suit on and secured!
