Abstract: A horizontal tube 1 having a mark 6 for the left foot position, and having a sequence of preferably three marks 3-5 for the right foot position for three ranges of club numbers. A shaft 10 is inserted transversely through the tube via one of three horizontal transverse holes 7-9 corresponding to the ranges of clubs indicated for the right foot. The shaft is tapered from end to end, and stops in a transverse hole at a position depending on the diameter of the hole. This position is designed such that the shaft extends forward a distance appropriate for ball placement for the given range of clubs. For adjustment, the user need only move the shaft to one of three holes. This configures the device for both the lateral and longitudinal placement of the feet relative to the ball, with minimal distraction and concentration.
