Abstract
Abstract A portable and foldable two-piece alignment training device for golfers includes two sets of elongated strips, each set having three strips hingeably joined at their first ends. The two strip sets are joined together by an adjustable slide clip and placed on the ground to form an "I". The "I" pattern keys the golfer to align his swing thereto. Indicia indicate tee position, the golfer's body and foot position, flight direction of the ball, and retraction distance of the club from the tee.
