A putt travels in the direction of the putter face at impact.
The purpose of the Putting Impact System is to help you learn how to see, feel, and repeat the correct impact position. The results are holed putts and a lot more fun! Practicing without a ball brings focus to the right fundamental - squaring the putter face at impact. Make strokes and learn to hit the Impact Plate straight forward.
If it rotates to the right, then the heel of the putter is hitting the plate before the toe. If it rotates to the left, the toe is hitting first.
The feedback is instant - no video needed. You know immediately if the face is square at impact.
