C-GROOVE - PERFORMANCE Using the Yes! C-Groove putter creates stabilization in the rolling motion dramatically sooner than any other putter. Forward rolling motion is as much as 6 times greater with the use of the Yes! C-Groove putter versus other putters. This result has been proven using a computer controlled putting robot and high-speed cameras. Over a 20 foot putt, the C-Groove putter was tested by an independent testing company against several putter models of the major golf companies. In all cases, the C-Groove putter dramatically outperformed the competition. Whether struck dead center, a millimeter or even a quarter inch off center, the C-Groove putter rolls the ball sooner, for more consistent length and more consistent direction. That translates to more putts made, no matter the circumstance, no matter the pressure. This technology has been proven in thousands of comparison tests performed by professional and amateur golfers at over 100 PGA Tour Events worldwide and at major trade shows in the U.S. and Europe
