Odyssey White Steel Tri-Ball SRT Putter. What could better the phenomenal success of the ground-breaking Odyssey two-ball? Step forward, the tri-ball! A hyper-extended mallet with a single-bend shaft, half-shaft offset and Saturn Ring Technology (SRT). With a higher MOI for a straighter back and through stroke, and a lightweight body for precise balance, this all-new alignment putter is an unbeatable blend of can't-miss technologies including: Lightweight milled aluminium body which allows for distribution of weight to the perimeter of the head. High-density Alloy Saturn Ring weighting system provides an optimum CG location to provide truer roll off the face and an enormous MOI to help resist twisting during the stroke and through impact. Proprietary Tri-Ball alignment systems make lining up putts even easier and more accurate. Modified White Hot urethane insert allows weight to be repositioned toward the back of the putter head, increasing the MOI for greater stability and forgiveness while providing soft feel and enhanced distance control. Milled stainless steel insert provides a constant, extremely flat surface for unbeatable accuracy while providing feedback with a positive sound.
