YES! GOLF MARYLIN C-GROOVE PUTTER
On any putt, a putter's impact on the golf ball can result in skid, sliding, back spin, and hop before the ball can roll on the green. Even on the right line, these are causes of missed putts. The key is a forward rolling motion upon striking. The Yes! Golf C-Groove putter does just that... Upon impact, the concentric edges on the C-Groove face grip the ball and apply force that lifts the ball out of its rest position and impart an topspin action.
Testing has been performed to compare consistency of distance and line for balls struck with identical force on a 50 ft. putt. These tests substantiated the fact that the C-Groove putter, due to its true roll, was more consistent in distance, and line. By hitting the ball on different points on each putter face, the same test also proved that the C-Groove putter had the least variance in direction, even on off centered hits.
