“What is DWW?” is an interesting thought exercise. What is DIR is rather clear … there’s a rule book (more or less) written by a cadre of authorities that is not hard to interpret. It is relatively rigid, dogmatic, inflexible and (if the proof is in the pudding) works real well. DIR draws flak from many elements in the diving industry for many different reasons, but the primary ones are, I think, economic, ego and past leadership personality problems.
I’ll leave the “ego” objections and past leadership problem to the realm of, “common knowledge.”
Some of the manufacturers don’t like DIR because their products are disparaged or they see it as too much investment in producing a diver per dollar of gear sales. Some of the agencies don’t like it because they follow the manufacturer’s lead, or because they are too far down their chosen path to turn back and they find it more cost effective to denigrate DIR than to redo their materials and retrain their people.
So now GUE has come through with a ten pool, ten O/W dive, 60 hour, DIR based entry-level program. Will the divers it produces be “better” than those coming out of current 18 hour, 4 dive recreational programs? Of course they will. Will the new GUE diver be “better” than someone who received conventional training that included some suite of additional courses (OW, Buoyancy, AOW, Rescue, Specialties?) I think the answer is still yes … but no quite as emphatically. I suspect that we‘d see two rather distinct distributions (measuring “betterness” on the abscissa and “numbers” on the ordinate):
- A broad curve that describes "most" divers, those with non-DIR training that would include everything from a 18 hour course up through a 100 hour course.
- The DIR course graduates (narrower curve) should have a high “betterness” score with a very low standard deviation,
The more conventional group would (again … I suspect) have a lower mean with a much higher standard deviation. It is these “tails” that are of interest to me. The “tail” on the down side (shown in red) indicate divers that are distinctly inferior to the DIR group, and the “tail” on the right side (green) indicates the few divers that are more capable (more better?) than the DIR group.
My interest in diver training rests within that upside tail. My experience is that most divers with about 100 hours of training and 14 to 16 open water dives fall into that tail. But that’s just what one would expect a positive relationship between the “Betterness Score” and amount of effectively provided training (as measured by hours and number of dives).
