Why not make your video with Trackman set up behind you to prove it. I interested in purchasing that.

I have a better wager. You get a player and a Trackman. Spend one day with him. I get him the next day and spend one hour with him. Let him be the judge.

I'm only trying to make a simple point. Low Point is needed to determine the Angle of Approach. Clubhead "Path" is not AOA. So, be aware that "Trackman" numbers will be very exaggerated and often beyond usefulness. Knowing the AOA will help narrow down the possible Swing Flaw(s). Using HK's geometry of the Circle, AOA rarely exceeds 1.5 degrees unless the Ball is positioned behind center of stance. Trackman correlates but I would read those numbers with a large dose of caution and "Cause-effect". This is where a little knowledge will do a lot of damage and a lot of knowledge will do less.

I would argue that until a player becomes somewhat skilful, that Trackman should stay on the shelf. Maybe much longer.

Understanding the geometry is the first step to identifying the critical alignments of the shot. Ball Location (AOA), Hookface (Face-alignment), Swing Plane (Shaft), Stance Width (Shaft Lean), Hinge Action, etc, etc.

I'm not criticizing "Trackmans" potential use as a tool, but it's no substitute for understanding the geometry and physics of Impact and it won't teach you these things.

Honestly, you can help a 15 handicap player reduce his play by 10 strokes simply by teaching him/her the "Right Forearm Angle of Approach" and "Hinge Action". About 15 minutes. I can only assume that it's not being taught because most TGM instructors aren't aware of or don't understand. How much better can you do? The teacher in the above video claims that "Drivers" and "Irons" need different swings. That is what Trackman has done. More confusion, misinformation and another decade of misguided teaching. Good luck with your purchase.

TGM is not invention. HK invented very little. It's about ten's of thousands of observations, definitions and codifications and much more. He didn't invent Hinging, nor RFAOA, or Sweep Release or even the Magic of the Right Forearm. These things were being done for hundred of years before HK wrote the book. A Golf-club and Golfer 200 years ago were subject to the same "Laws" governing the Swing today. "Law" and "Technique" are not the same.
