Twenty years ago Guerin Rife designed putters with closely spaced grooves running across the face allowing a putter to roll the ball smoothly at impact. Despite initial resistance, many major golf manufacturers using alternate versions of Guerin’s original groove technology now use this idea.
While closely spaced grooves create a superior roll they also soften the impact. Simply stated, less contact surface means less hit. In tests, a ball hit in the center of a non-grooved putter travelled 25 feet. That same putter with grooves with just a quarter of the contact surface only reached 23.5 feet.
Introducing Evnroll®. Precise patented face milling imparts progressively more energy transfer on off-center hits to roll the ball a consistent distance with every stroke.
