A man is swinging a golf club. Imparting spin to a golf ball is critical for producing shots of significant distance and sufficient accuracy. The construction of the ball and the club guarantee a high degree of rotation. Over the years as golf ball and club designs have improved, club makers discovered that for many players limiting the spin on shots with the driver allows them to achieve more distance off the tee.
