Abstract: A ball used in sports that is normally propelled to a target includes markings for sighting of the ball to the target by aligning the markings on the ball with the intended line of travel and then focusing on the markings as the ball travels to the target and observing the markings to determine the uniformity of ball rotation. Markings on the ball also serve to make it possible to note the number of revolutions the ball makes in traveling to the target, thereby increasing the sportsman's awareness, concentration and accuracy. Specific indicia markings are disclosed for golf balls and basketballs as examples.

Abstract: A ball used in sports that is normally propelled to a target includes markings for sighting of the ball to the target by aligning the markings on the ball with the intended line of travel and then focusing on the markings as the ball travels to the target and observing the markings to determine the uniformity of ball rotation. Markings on the ball also serve to make it possible to note the number of revolutions the ball makes in traveling to the target, thereby increasing the sportsman's awareness, concentration and accuracy. Specific indicia markings are disclosed for golf balls and basketballs as examples. In the case of a conventional basketball, indicia extends transversely across the panels and substantially around the ball at the center, giving the appearance of a continuous 360.degree. line when the ball is rotated uniformly.
