This may be stoking the fire but, no agency in the world would advocate that sort of trim in diving. None. So the "if there was no DIR ......." falls rather flat. Unless of course you are saying that every other agency actively ecourages poor control and trim.
Better configuration? According to who?
This is where the "elitist" tags come from. No-one else could possibly have decent trim and buoyancy. Heaven forbid I dive with someone who has the kit set differently to mine.
Thanks, this is the response thought I wanted to address.
Back up to 1995, before DIR hit rec.scuba.....
Unless you were WKPP, you had never heard of it, and thoughts about the right or the best or the optimal gear configuration, were poorly defined. There were very strong divers, with good gear configurations, but what was very good in their set ups, was not expressed in any useful way for the masses without the good gear configurations.
Even today, many agencies do not want to touch "optimal gear configuration". However, there are shops selling bad gear combinations, often due to the sale taking place by a kid with little diving knowledge, and then slapped on to the backs of the diver, with little thought. An instructor might wince at the look of some set ups, but if not life threatening, many would not decide it is in their purvey to wade in to this mess.
DIR thought is different. When we see gear that does not work well, or is configured in a way that will restrict function, or cause an unsafe situation, DIR has a direction for this, and a better way.
There were probably 10 to 15 dive instructors that saw this guy during the dive....I would question if any thought he was safe in the water. None said anything to him.... Again, maybe I am part of the problem this thread details ( because I pushed a DIR agenda to a diver that I thought needed help) ...but I felt there was a better way this guy should know about, and I felt it would be wrong not to share it.
