Abstract

Abstract A golf club swing training device provides a base, preferably in the form of a mat having an artificial grass surrface, with a plurality of openings at predetermined locations spaced about the mat for selective disposition of upstanding swing guide members to permit the user to arrange the guide members to define any desired golf club swing path, e.g. an inside-to-square path for full golf swings or a straight path for chipping swings. A mirror-image set of guide member placement locations is provided to enable the mat to be used by both left-handed and right-handed golfers.
