Abstract
Abstract There is disclosed herein a golfer's training device particularly adapted for use in indicating head movement during the execution of a golf swing through utilization of the parallax principle. The training device comprises a target containing member supported upon a base member, the target member having a sighting object supported in a spaced relationship thereto so as to be alignable with a portion of a target provided on the target member as the golfer addresses a golf ball in preparation for a golf swing. In one form a base member is integrally molded with the target member and comprises a generally three-legged supporting structure. In another embodiment, the base member includes a spike projection extending downward from the lower portion of the target member which is adapted to be inserted into the ground so as to support the target member in proper relationship to a golfer as he is about to execute a swing. In this embodiment, a ground engaging base member is also provided for supporting the spike projection so as to enable the training device to be used indoors such as may be desired during winter months. The target containing member may be in the form of an upwardly facing arcuate surface having a grid-like network of lines thereon.
