0-0 on Trackman vs. 0-0 Episode 1

[hammer3612]

I was rewatching Brian's Episode 1 video on Youtube and he talked about a 0-0 face and path on an old Mitsubishi swing monitor that produced the ball going left. So why does 0-0 on Trackman produce a different shot? Does it have to do with the difference between impact and separation?

Great Question but 'No', it is the fact that the ball flight is measured in 3D now and 2D previously as per the old machine. We are looking for a 0 as a result. The required inward path to hit a 6 iron straight is approx 3deg., each iron will differ due to the differing verical plane changes.

My two cents... the old machine would have measured face angle and path of the club. Both of them at zero/straight, but didnt include the down.

But, since the fact that the machine did not measure the amount of down in the strike it was giving a misguided number. Assuming that you had zero for both the clubface and the path, but you are hitting down on the shot, the actual swing path is to the right.

So, if the face was square to the target and the "actual" path was to the right of the target the ball would start just right of the face and then curve back to the left and end up on the left side of the target.

In order to hit a straigh shot at the target you need the face to be square to the target and the "net" path to also be square. The more you hit down on it the more to the left you have to swing to in order to achieve a "net" zero path reading.

Hope this makes sense.
