Eyeline Golf - Roll Board
In a single stroke the Roll Board will show the roll of the ball – where it was struck and when it began rolling on the surface. Make your adjustment of shaft lean or ball position, and your 2nd stroke will improve instantly.
Don’t worry about your “combination”, the Roll Board will give you the answer.
Yes, it is THAT quick. Hit a few putts every time you practice to fine-tune your position, and hit end-over-end perfect putts.
