Its hard to imagine anyone claiming to have invented proper buoyancy control, buddy awareness, or even back plate and wings with a straight face. I never got the impression during class that they were showing me something new, quite the contrary this was all stuff that I should have known (proper buoyancy, trim, etc.). I had heard most of it before, it was just buried under a mountain of fluff.
Actually, proper buoyancy control is not that old. I experiemented with it in the 1970's on equipment manufactured by Bill Herder of Newport, Oregon. We actually had a better design that the "wings" currently in vogue by making the back of a wet suit a bladder. It was more streamlined than current BCs, and did essentially the same job. The reason that the
New Science of Skin and Scuba Diving did not show these things is that they had not been invented yet.
Someone asked if some of us who've been around a while have seen the same types of teaching techniques as currently in the DIR courses. Well, yes and no. I have not taken the DIR classes, and have no current plans no either, so I have no direct knowledge of what they teach. I do remember that NASDS was very closely tied to Scubapro and the AtPak, and that there was an attitude that if you weren't diving those, you were somehow inferior; I see this kind of attitude being hooked to DIR now. I'm not sure who is doing the hooking either, but I suspect it is a combination of the DIR instructors, students, and sometimes a reaction to them too.
I will tell you that the DIR class probably doesn't hold a candle to the U.S. Navy School for Underwater Swimmers course that I took in 1967 (again I'm not certain, but it's not too conceivable that it is that intense). I don't hear of DIR students doing pushups with twin 90s on their backs, or face-up flutter kicks on top of their tanks with a facemask full of water, or running for an hour, or swimming 1500 yard compass courses, or doing the "pool harrassment" typical of the U.S. Navy, but perhaps they do. I'll tell you though, to graduate from that course, you had to be fairly comfortable in the water.
Hopefully, dive instruction is not so "military" as that described above; but I would like to have students who are comfortable in the water, and can handle themselves. Maybe that is what DIR is all about.
