The Visio putting balls pack offers a simple but effective way to get feedback on your stroke mechanics and remove the frustration of missed putts. The pack comes with 3 distinctly designed balls. A crosshair design, a triple line design and a 50/50 black/white design.
Using the different designs and their unique alignment features you can assess the spin and launch of the ball. Feedback on the spin and launch will help you determine the impact conditions of your putt which in turn give you the feedback you need to help you improve your stroke.
