The Spin is an understable putter based on the Ion/Anode core with all the glidey depth that comes along with it. While understable putters traditionally have a niche usage, the Spin solves their overly touchy and wind-sensitive Achilles Heel through GYRO™ Overmold Technology. Since the turnover of the disc is buffered by gyroscopic resistance to turn, those low speed turnover lines are far more reliable with the Spin. Flip-ups, turnovers, high panning shots, and nose-up stall shots are effortless and reliable.
