A sighting device, for use by a golfer while standing on a ground surface and gazing at a golf ball upon the ground surface at a natural viewing angle, and hitting the golf ball. The device has a stand which includes a base for resting on the ground surface in front of the golfer, and a vertical mast. A pair of rings are suspended by the vertical mast in the path of the natural viewing angle. The rings have alignment indicia. Accordingly, the golfer observes the golf ball through the rings with both rings are concentric with the golf ball, and the alignment indicia of both rings are arranged in a straight line. Any movement of the golfer's head during the golf swing is immediately revealed to the golfer by a change in relative position between the rings and ball, and the alignment indicia deviating from a straight line.
