Sorry Trace, I'm just missing the point. I'm not trying to disagree with you, but I'm not quite clear what point your trying to make.
could you just try to reduce this down to a simple and blunt point.
The blunt point: Assuming that technical diving instructors have higher degrees of experience and skill levels than technical divers, how does it benefit anyone to allow technical divers to teach a technical diving course rather than a technical diving instructor? Answer: It doesn't.
An SDI instructor is a recreational instructor, but still only a technical diver.
Additional understanding:
Why don't we just make anyone who graduates from a technical class into a recreational instructor? I believe the answer to that is that there is a lot that a technical diver doesn't know about being a diving instructor at any level.
There is a lot that a technical diver doesn't know about teaching technical diving and safeguarding the well-being of students. Even an excellent recreational instructor may not have the diving experience and internship experience to be prepared for the possible risks we experience in technical education. For example, one thing that I do to safeguard the well-being of my students is position myself so that I can intercept a DSMB or liftbag if the student becomes entangled in the line. In addition, I have a hook knife in my left hand during DSMB and bag deployments. This will allow my right hand to be free for a long hose deployment if necessary. Once the bag is safely deployed, I'll quickly replace the knife. If the bag catches a student and I cannot intercept, or fail to intercept the bag, I can quickly cut the line to protect the student from being pulled to the surface. The use of a hook knife allows my fingers to be free if a student simultaneously loses buoyancy control to help arrest his or her descent if the student fails to do so. I've cut the lines on 3 such dangerous deployments in my career without the diver even changing depth once hopelessly snared. That is just one small example of the forethought a technical instructor brings to the table. Experience comes from diving and from taking classes and interning with excellent technical instructors and instructor trainers. It isn't enough for me to believe I can handle a possible problem. I want to know that I can. Technical instructors have spent a lot of time as both technical divers and as experienced educators, so while the exceptional recreational instructor can teach a good technical program, even a mediocre technical instructor will do a better job than most recreational instructors and an excellent technical instructor is priceless.
Summary:
I believe that allowing technical divers (who may be recreational instructors) to teach Intro To Tech will reduce the quality of the program because they are not technical instructors and haven't developed the skills and experience that will benefit SDI/TDI, the stores for which they work, or the diving industry in general in the long run - with a few exceptions - but, those exceptional instructors would also benefit SDI/TDI, dive centers and the industry even more by becoming TDI technical instructors.
