Spin Putter
The Spin is an understable putter that debuted in Electron in the 2016 Circuit Player’s Pack.
The Spin has a deep profile like the Ion and Anode, which makes it great for glide-filled lofty flights. Its controlled understability makes it suitable for both new and advanced players alike.
The Proton Spin brings die-hard premium plastic to a truly unique model in the MVP lineup. 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. In Proton plastic, the Spin will retain its fresh stability for extremely long, keeping it in the sweet spot longer than any other turnover putter.
