Abstract: A golf stroke instruction device comprising an elongate, pivotally mounted club-engaging component whose range of motion can be selectively controlled by the user. This novel club-engaging component is operatively mounted adjacent at least one generally vertically disposed planar member. The planar member has an upper portion upon which the component is pivotally mounted for free swinging motion, with the planar member also having a face portion as well as a pair of side portions. A motion-limiting arrangement is utilized on each side portion of the planar member, serving to limit the motion of the club-engaging component as it moves along the face portion of the planar member and approaches a side portion.
