DIR
Diving Irresponsibly Ridiculous...
Not fair to apply to all DIR people... but I'm amazed at the number of people who sign on to this philosophy (which is really what it is,) begin configuring their gear in a certain manner and then begin telling everyone else they don't know what they're doing.
If you wan't to buy into the DIR philosophy, I've got no problem with it. The program itself is not particularly bad... it is the attitude of those who sign on with it and then think and espouse that everyone who is not DIR is wrong.
My experience (which is far more extensive then most) has lead me to believe that a diver should dive that with which they are comfortable in, confident in (i.e. believe in) and that they both like and can afford.
Learning philosophy aside, a DIR person has never taught or showed me anything I didn't already know. Now for new divers, I think an introduction to DIR is fair... but not the relentless telling that if they don't dive DIR - then they're not "doing it right."
DIR... "Doing it Right" in itself implies that if you're not DIR then you're wrong... which is I'm quite certain they will all say about me after this post...
Find what you like, dive what you like and learn from a quality Instructor... DIR or not - doesn't matter.
