The ION is a renowned stable-to-overstable putter that excels in putt/approach duties as well as high-power putter driving. The ION features MVP's signature GYRO Technology, which uses a two-piece construction chemically fused into one solid indestructible union. GYRO places a more dense material at the outer edge to add weight, which enhances the gyroscopic force of the disc when thrown up to speed. With more gyroscopic force, the disc remains oriented for maximum flight longer, much like an airplane wing. Gyroscopics are the essence of why discs fly, and GYRO maximizes the aerodynamic design of the wing.
Grippy and every bit as durable as their Proton plastic, Neutron also features several high-visibility neon colors. The flex on this Ion is the firmer of the two types, which MVP previously called "Medium" flex. MVP now only designates the flex on their soft putters, leaving these firm types as simply regular Neutron.
