Back to the original question...
The name does endanger the concept. Doing it Safer, Doing it together, Tech Divers Unite, whatever, anything would have been better.
The name impliess that the rest of us have lousy skills. Dosen't really invite me to find out more. Then, what I see is a bunch of morons (who are likely NOT trained) spouting off..so this represents all I've heard about DIR - a few dorks at a dive site who were just trained in tech and have been spending too much time on the internet.
NOT really knowing about DIR, have no desire to, really, but the name implies ego - likely NOT a trait exhibited by the individuals who truly are behind the program. DIR should have protected their image more.
As far as I'm aware, the folks who have the greatest safety record are those who are cave trained, from the orginal cave (ie not padi, not iantd, etcc) cert agency. According to the statistics I've seen, this is the group with the lowest accident rate. I guess that's where I base my decision - the ones who don't need to advertise, but have a quiet confidence.
