I have to be the flame thrower here: DIR people practice drills all the time. DIR people do an in water check even after the on shore/deck check. DIR people don't dive with unsafe divers, which is probably why some unsafe divers dive solo. I don't have the link here, but an unsafe diver per DIR is not just a recreational diver. There several attributes.
OK so it is not to say that DIR divers never get into trouble. In fact I have read their posts here. Have heard of DIRs turning off valves underwater just to drill. There was a thread not too long ago about realistic training such as turning off someones gas, snatching their mask, snatching a fin. There were other antics suggested. But seriously, what about over weighting someone and having a trainee react to get them before they fall to the bottom which is 175 feet? Even buddy breathing. Everyone says an OOA diver is going to grab your regulator not your octo. So if I grab your regulator, what are you going to do?
I think that just because you pay your money, you shouldn't automatically get certified. How about a partial refund? How a report to the dive certification agency that this person shouldn't be certified? Oow I bet that's better than saying DIR
I do agree though that diving is not and should not be taken lightly. What are the demographics in terms of male, female and age range? I started trying to look up statistics for other activities such as sky diving, motorcycle riding street and off road, and other demanding sports/hobbies. I should start that again and try to compare.
