Abstract:
1. Apparatus for objectively calibrating orientation of a putter to facilitate consistent putting strokes by a golfer, said putter having an axial shaft and a head having a sole and a face, the sole and shaft defining a lie angle and the face having a loft, the apparatus comprising: a plurality of first position-indicating indicia disposed along the putter shaft; a plurality of second position-indicating indicia disposed along an elongate axial calibration member supported generally parallel to and spaced above a generally planar putting surface; and said first and second plural position-indicating indicia are positioned and arranged such that placement of the putter shaft against the calibration member with the sole generally flat against the putting surface and with the face oriented with a generally neutral loft causes the first and second indicia to align at a calibration point corresponding to a neutral putter position; whereby the putter may be consistently re-positioned at the neutral putter position after each putting stroke by placing the putter shaft against the calibration member at the calibration point.
