I would hope that Trackman will record the Ball Flights accurately and compute any minor differences in Geometry. That's not the problem. But, a problem does exist if you look at the numbers in the above video and conclude that a Driver should be swung with a different geometry than a Nine Iron. That they can be different is not the problem either. That they "Should be different for the same Player" is the problem.

In the above video, Trackman shows that it's possible to use different Plane Angles and Angles of Approach and Attack and still result in a straight shot. Really??? is that new??? No, of course not. But the teacher concludes that that's just the way things are. That's why I have a problem with the video and the teacher. That's not the way things are, should be or need to be. In the right hands, Trackman should be an asset to the teacher, but in the wrong teachers hands, it will be the undoing of a potentially good player, who's paying big bucks while being led to believe that this is the best solution.

Trackman is a TOOL. And, as it is with all "tools", it's ONLY as good as the person who uses it. If you as a teacher don't have a firm grasp of golf alignments, then maybe you should learn these first before you spend good money on an overpriced piece of equipment. The teacher in the video is very confident that what he teaches is fundamentally sound and correct. Nothing new about that, either.

There is no doubt that trackman should be used as a tool and not the doctor. People that use it to attack folks are as in the wrong as people that think it's useless or a symbol of evil.

Daryl, I do have a few questions for you: Please keep in mind Im not trying to attack or debunk, I have my opinions and beliefs, you have yours....that's fine. Im genuinely interested in your answers.

(1) Do you think there is one straight correct plane for all clubs after only a minor change in ball position through the bag?

(2) Why do golf balls do different things when the same club is hit more and less down on with the same clubface?

(3) Do you see guys on tv all swinging straight?, and if not, are they wrong or at least inefficient?

(4) How thick is the correct plane? If my analyzing software draws lines that are twice as thick as yours, do they still count? 3x? How many clubshaft widths could fit in one plane before it's off plane?

(5) If a certain attack angle creates a certain path and shot, but you want to alter the shot, and rotate the whole plane line to do so........doesn't that change the attack angle AGAIN? Wouldn't we end up continuously rotating around in a circle?

Just in straight away lehman's terms will do. I have conceded that you are smarter than me.
