Abstract
A Planar-Parallactic Golf Alignment Aide is disclosed. Also disclosed is a device that provides the golfer with a planar alignment sight line for aligning the club face with the target. The invention further provides the golfer with a parallactic alignment sight line for placing his or her head in the proper and repeatable position in order to eliminate unintentional stance variations. The aide may be incorporated within the club head and operate by aligning an aperture or line with the projected image of that aperture or line to use the phenomena of parallax for head alignment. The aperture or line is formed in the top of a dome, and the projected image then appears on a projection surface below the dome. The device may either be an attachment for a conventional club head, or may incorporated into the head itself.
