Abstract
Abstract A golf practice device comprising a track secured to a fixed mounting surface, such as a wall, post or the like; a carriage guided for movement along the track and a flexible tension member connecting the carriage to the shaft of a golf club. The tension member is adjustable for length. The golf club is guided in a path of movement which lies generally in a plane parallel to the plane of the track. The track is of a smaller dimension and similar in shape to the path of movement.
