Abstract
A sighting device for enhancing a golfer's putting accuracy comprises an elongated vertical sight and a liquid level, which are provided by a compact hand-held, semitransparent or translucent casing with particular indicia and contained liquid. After the golfer moves to a position at which he views the ball and the cup along their shortest interjacent path, he views the position of the cup with respect to the ball in reference to the sight and plumbs the sight in reference to the level. A correct indication of how the ball will break thereby is provided.
