Golf practicing apparatus characterized in the use of adjacent strips of luminescent or light-emitting material on the upper surface of a golf club in a manner such that when the club is swung through an arc, a visible trace pattern is emitted by the luminescent or light-emitting material which enables an observer to make a rapid and accurate determination as to the disposition of the golf club head throughout its arcuate path of travel. The pattern comprises three adjacent stripes of outer black stripes and an intermediate stripe of red. Luminescent reference guide stripes in the path of travel of the club are also provided one of which stripes is tangential to the path of travel of the club and the other of which guide stripes is perpendicular thereto and at a point of impact of a golf ball. Another form of the invention includes stripes of a luminescent chemical that are covered with a cover that is ruptured prior to use so that airborne oxygen reacts with the chemical to yield a distinctively colored light pattern when the club is swung through an arc.
