The Pro-D Zone, released in July 2008, is a very over-stable putt and approach disc. The Zone is designed for players who are looking for an overstable putter, and can be used for hyzer putts, spike hyzers, or long approaches that require a more stable disc. Because it is overstable, the Zone is outstanding for putting in heavy winds.
This disc has been produced in limited quantities and is available for a short period of time.
