A laser is mounted in the head of a putter so that its beam can be directed through an opening in the plane, ball engaging surface of the putter along a path which extends normal to the putter face, and parallel to a first sighting line positioned on the upper surface of the putter head. While for test purposes a golfer aims the sighting line toward the center of a simulated putting hole target, which is spaced from the head, the laser is energized to direct its beam toward the target. The extent of the misalignment of the putter face with the simulated hole will be indicated by the extent to which the light beam is angularly offset from the center of the target. The first sighting line is then replaced by a second sighting line reflecting this angular offset.
