If you have spent time with a putting instructor, he or she has probably had you putt a ball in the center of 4 balls to ensure a smooth, and straight putting stroke. The problem is replicating the position of those 4 balls to best suit your natural putting stroke when your pro is not around... until now.
The 4 Ball Pro is a ball positioning aid that places 4 balls strategically around the ball you will strike. Each position is adjustable to accommodate any putting stroke, whether pendulum or arc, as well as any putter gap. You can start with a wide putter gap, and then narrow the gap as your stroke improves.
With the four balls set around your target ball, lined correctly to the target, it is virtually impossible to miss a putt when the putter "swings through the gate" properly. Check the video below out to see what we mean! It won't take very long for the 4 Ball Pro to call attention to flaws in your putting stroke, and begin to correct them.
