Robot Testing

Robot testing was also conducted to compare consistency of distance and line for balls struck with identical force numerous times on a 50' putt. These tests substantiated the fact that the C-Groove putter, due to its truer roll, was more consistent in distance and line. By hitting the ball

The story of success.


How C-Grooves Work

By gripping the back of the ball and lifting it forward on impact, the C-Grooves of a Yes putter create almost instant stabilization, causing the ball to roll forward much sooner than any other putter. In fact, as much as six times sooner.

The naked eye can’t see it, but when a regular putter face impacts a golf ball it results in loft causing skidding, side- and even back-spinning before the ball can begin rolling forward on the green. So the ball is more apt to be affected by any miniscule aberration it encounters. Even when struck on the right line, these effects are the principal causes of missed putts.

The C-Groove on every Yes! putter solves this problem better than any other putter on the market. Which is why it’s covered by multiple patents.

The secret is the 20-degree upward slant of the C-Groove’s concentric edges. Upon contact, these edges grip the ball surface and apply physical forces that simultaneously lift the ball out of its resting position and impart an over-the-top rolling motion.

The illustration to the right is a detailed summary of multiple 20” test putts as conducted by an independent testing firm. Using a putting robot and a 100-frame-per-second video camera, they were able to show how the C-Groove putter dramatically and consistently outperforms the putters of other major golf companies.

Balls struck with the Yes! C-Grooves invariably achieved forward roll quicker than balls struck by competitive putters which repeatedly skidded, skipped and spun before settling into forward roll in approximately 18 inches.

And the sooner a ball achieves smooth forward roll, the better the line it will have and the less likely it is to be affected by aberrations in the green. In short, more putts will drop in.

Even when struck up to a quarter of an inch off center, the C-Groove putter rolls the ball sooner and more consistently.
