PING announces Karsten TR putter

Building on the success of last year's Scottsdale TR ("True Roll") putter line -- Derek Ernst won the Wells Fargo Championship with a Scottsdale TR Grayhawk -- PING announced the addition of a new Karsten TR line that features five new models with the company's variable-depth-groove technology on the putter face.

Through testing, PING found that grooves reduce the velocity of a ball coming off the clubface, and that the deeper they made the grooves, the more ball speed was lost.

By varying the depth of the grooves across the face -- with the deepest grooves in the center and getting gradually shallower toward the perimeter to equalize ball speed -- they were able to improve distance control on center-hit and mis-hit putts off the heel or toe.

When PING debuted variable-depth grooves last April, the technology was added to the face via an insert. With the Karsten TR line, the grooves were milled directly into the face of the 17-4 stainless steel head.

In an effort to enhance sound and feel, an elastomer badge was also added to the cavity of each putter.

Unlike the Scottsdale TR putters that came in a black PVD finish, the Karsten TR putters come with a distinctive copper PVD finish.

Each putter is also optimized for a particular stroke type. The Anser 2 (345g), B60 (345g) and PAL are for golfers with a slight arc stroke. The Anser 5 (365g) is for a straight stroke type, and the Zing (350g) for a strong arc stroke.

The entire line will be available in February for $162 with a fixed-length shaft (35 inches is standard). Adjustable-length versions that can be moved between 31 inches and 38 inches will also be available for $197.
