And then there is your average technical diver with not enough training, doing dives they shouldn't be doing...
While i have never had any formal tech diver training, I do quite a few "Tech" dives.....However I think alot of it relates to how much experiance you have doing the dives, and how much know how you have about the dive you are going to do.....Mind you i dont do penetration dives at 250fsw, but I dont think you need to be a genius to teach yourself how to dive to 250fsw either. Dont get me wrong I think that training is a great idea, and should be utilized if available, but at the same time an average diver can learn the "Average Tech Diver Skills" with little more than a book and some good dedicated practice.
I'm probably gonna catch falk over this post, but its just the way i feel.
