More Information
Summary:A thickness checking pointer for billiard practice is provided, where while being fitted to a finger supporting a cue stick, the thickness checking pointer guides the cue stick to move in a straight line during forward and backward preparation motion or hitting motion of the cue stick, and emits a horizontal light beam in a travelling direction of the cue stick, so as to not only check which shape into which a cue ball and an object ball are arranged on the same straight line as the cue stick but also estimate the degree of thickness by which the cue ball moved upon hitting collides with the object ball, thereby enabling even beginners to easily understand billiards.
