The Ping Karsten Zing putter is a perfect choice for golfers who prefer the performance and feedback of a steel face with the added benefits of an insert feel. This has been achieved by adding an elastomer insert in the cavity thus providing enhanced feel while maintaining the solid response of a steel-faced putter. Weight savings from the new cavity shapes have been redistributed to the perimeter to increase each putter's moment-of-inertia for added forgiveness. Multi-level alignment aids are also designed into most models. The Ping Karsten Zing putter represents the latest advancement in feel, forgiveness and alignment options, and as always with Ping, has been designed so that it can be custom fitted to suit individual putting strokes.
