I have to take 10-20 lbs of lead off of my divers. I have to do it slowly, over the course of a week, because their OW instructor (you pick the flavor) told them that's how much lead they needed. When they learn to dive with 12 lbs and their air consumption is cut in half, great, we all celebrate, but it wasn't necessary to overweight them in the first place. But because they were overweighted in OW class, then it must be the right thing to do. I used to get deckhands out of a famous instructor mill in Marathon FL that came to my boat as crew who wore 24 lbs in a 3 mil and aluminum tank. This is crappy instruction, folks, pure and simple. And that instructor mill will present you with whichever instructor certificate you want, once you find a job at a dive shop.
With this I fully agree, and I think you know I have been on a crusade for years to do away with this practice. That crusade has had a positive effect. I led a group that got an article published on this topic in the PADI professional journal (which you don't read, apparently), and that article (and the discussions we had leading up to its final draft) led to PADI changing its instructional materials to
recommend that all instruction be done while neutrally buoyant and in horizontal trim rather than on the knees. In the first annual regional session I attended after that, the regional director rhapsodized at length about much better the students turn out when they are taught off the knees. Unfortunately, they only
recommended it, and most instructors are sticking to what they have always done. The instructor mills you talk about are the biggest offenders, and I had a long talk with PADI headquarters last year in which I was told why it was true.
As it was explained to me, the instructor mills guarantee that their students will pass the Instructor Exam, and to make that happen they have developed very precise ways of doing things over the years. They have looked at every required skill and thought of everything an instructor examiner might be looking for in a skill. They put all those possibilities into the skills they teach their students. That creates overly elaborate and unnecessary processes on which the students are drilled and drilled and drilled and drilled until they can do it perfectly. The person to whom I spoke, an instructor examiner himself, said that if you were to line up all the instructor candidates from a program like that and have them start a skill at the same time, it would look like a synchronized swimming event.
Except there would be no swimming. In order to do skills that way while on the knees, the diver must not only be overweighted, the diver must be
significantly overweighted. When I instruct, I am a little overweighted so I can deal more effectively with any potential problem with a student. When I posed for the pictures for the aforementioned PADI article, I was weighted as I normally am when doing the skills in horizontal trim. Then I had to pose for the pictures on the knees, which I had not done in many years, and I could not do them. I had to pile on the weight in order to stay solidly anchored to the floor of the pool.
So why was I having this conversation with PADI? It sprang from an experience at the shop where I was then teaching OW classes. The shop had hired a recent graduate of an instructor mill at Roatan to be its director if instruction, and he was insisting that we require our divemaster candidates to do the elaborate choreography (heavily weighted and on the knees) he had learned in that program. He even insisted that doing some of the skills the way I did it violated standards. If I wanted to work with the DMCs, I would have to do it that way. I contacted PADI to ask about the standards part, and I was told that everything I was doing was perfectly fine; in fact, what I was doing was much preferred. The way the mills teach their students was still acceptable, though, and it was up to the shop to determine how we were to teach. It was up to me to decide if I was willing to compromise to meet their rules. I chose not to work under those conditions.
So, PADI prefers that its students
not be taught the way they are, but until they require that instructors stop teaching skills on the knees, things will not change all that much. At least they have taken that first step of recommending it. I don't know what any of the other agencies have done in this regard. I do know that the person now in charge of instruction for the North Americas for SSI recently crossed over from PADI. He was my Course Director when I developed my methodology, and he was a signer of the article we published. When he saw how much better students learned using that methodology, he required it of all instructors in the shop in which he was then working. I therefore would guess that SSI will be making a change at some point.
