String Theory Training Aid Putter
Master the perfect putting stroke through feel, rhythm, and instant feedback.
The String Theory Putting Aid uses a patented weighted-string design to help golfers develop a smooth, consistent, and natural putting motion. By swinging the weighted string like a pendulum, you’ll learn to control the club head using centrifugal force—the same principle behind every great putting stroke.
Every swing gives you immediate feedback—if your motion is smooth and straight, the string stays in line. If not, you’ll see and feel it instantly. Over time, this builds muscle memory for a perfect, repeatable stroke.
Note: This is a training tool only and not for use during official rounds of play.
