摘要 This device is attachable to a golf club, so as to enable a golfer to sight more accurately on the hole, in which he or she wants to place a golf ball, and it consists primarily of a plate with a removable sight rod, which is secured to the top of the putter blade. It further includes a multiple number of recesses in the plate, which are spaced in degrees of angle, for setting the angle of the rod to any desired position by a spring-urged ball in the pivotal portion of the sight rod.
