  • Patent number: 7780542
    Abstract: A golf training device and process are disclosed for assisting a golf player in aligning a golf club through an arcuate path for contacting a golf ball. The golf training device comprises a plate including a face side and a back side. The face side of the plate has a first color. The back side of the plate has a second color. An exterior edge of the plate has a third color. A coupler extends between the interior edge of the plate and the shaft of the golf club for securing the plate to the golf club. The third color alone is visible during the golf player swinging the golf club for producing a perpendicular alignment between the face surface of the golf club and the ball. The perpendicular alignment between the face surface of the golf club and the ball propels the ball in a straight trajectory.
