ABSTRACT:
A golf putter in which most of the clubhead mass is distributed at three or more individual or one or more arcuate locations within a “Mass Ring” approximately equidistant from, and as remote as possible from, the clubhead planar center of mass with the clubshaft axis preferably forward of the clubhead center of mass thus maximizing both putter and clubhead planar moment of inertia for improved putter performance during mis-hits. Maximum remote mass is achieved by interconnecting the remote high mass areas (Mass Ring) with the putterface striking area and the putter shaft connection point with a light weight rigid open (see thru) truss system so arranged to enhance the visibility of the Sighting Field and/or aim or Sight Line on the putterhead while preventing undesirable vibration of individual clubhead members.
