How to put visual control points on a device






Two visual control points used for Bullet Stroke devices. The lower point is red or blue, for a device position control in a preparation stage. The upper point is yellow, for a device pass control, direction and position in a time of impact.  When practicing, a player keeps visual control points in a view. After many repetitions, the right preparation position and action movements begin to be subconscious, no need to control, only be focused on a target. Colored, 3/4 or 1/2 inch (1.9 or 1.27 cm), PVC tapes can be purchased at any hardware department store.
