As I said before, I believe in the "Dive and Let Dive" mentality. But after reading for awhile I did a bit of math and marketing evaluation of the situation. It is my understanding that 96% of divers are recreational or vacation divers that have no DIR/GUE training. Of those 4% with DIR training, I would venture to say 75% will not dive cave or wrecks on a regular basis. So, we are down to less than 1% of all divers that need or rely on DIR/GUE training for the diving that they do. From a marketing perspective, this is not where you want to spend your research dollars. The market is too small, maybe one or two specialized companies can do it, but not everyone. The real money is with the other 99%.
This also means that 99% of divers don't need and I would say 80% of divers don't want that level of training or skills. Why, the cost and time required to attain it is not warranted for the diving that they intend to enjoy. They just want to get underwater and see the pretty fish. So, why would the instructors who are teaching this 80% of divers waste their time getting that same training. I am not saying that none do, I am asking what is the incentive. Yes, we all have personal incentives to be better, but most are not willing to spend the time and money that has little return on investment.
I believe DIR/GUE has a place in the industry, but it is a very small place. It appears that some here on SB want it to be the only way to dive. Unfortunately, the math does not add up to that. My LDS is a GUE shop, great people, never comment on my gear setup. I understand what they are doing, they understand why I have the equipment that I use. Simple Dive and Let Dive understanding.
Now I know someone is going to comment on my numbers, I won't argue, they are rounded. Even if I am off by 5% (large margin of error), I still believe the same is true.
Nothing wrong with the "DIR" philosophy. It should be the industry standard. "DIR-minded" divers are typically safer, more skilled, and more reliable divers than the typical divers who were trained by the big names like PADI.
The problem is most definitely the assholish attitude of GUE divers. They've earned their poor reputation. I've never had a PADI instructor who was as angry and sadistic as GUE instructors.
Depends upon your interpretation of what DIR actually means.
If you interpret DIR as having great skills--not accepting mediocre or poor skills--through practice then those skills make recreational diving much safer and more pleasurable.
If you interpret DIR as mainly equipment and procedure Dogma then it's hard to see how that would apply to recreational (non technical) diving.
The latter are the tiresome DIR-warriors. The former are great divers.
