ABSTRACT:
A golf putter with sighting device comprising a putter blade attached to a standard shaft and handle. The blade includes an essentially planar surface with a circular threaded cavity which is of sufficient depth to receive a cylindrical threaded core of substantially the same cross dimensions as said cavity including two essentially planar ends, one of such ends including a circular liquid level. The core may be invertedly threaded into the cavity such that either end of the core may be exposed upon the blade surface. It is intended that the level containing end be exposed for practice play and then invertedly threaded back into the cavity such that it is now embedded within the cavity and now qualified for regulation play with no depreciable effect to the putter, such as a shift in weight.
