Abstract: A golf swing training club consisting of a club head, a length adjustable shaft, and a grip. A light source housed inside the grip projects, when illuminated, a highly focused beam of light outward from the top of the grip to track the player's swing plane. The light source, typically a diode laser module with power source, is removably secured within the grip by means of a collar and plug connector. Formed into the grip is a pressure sensitive switch which controls the light source. The light source is turned on whenever the grip is grasped and is turned off once the grip is released. A means for removably mounting training weights along the length of the shaft is also described.
