Abstract:
The present invention relates to a thickness checking pointer for billiard practice, the pointer being inserted between fingers supporting a cue stick, so as to emit vertical light in the proceeding direction of the cue stick while guiding the cue stick to move in a straight line during front and back preparation movements or striking movements of the cue stick, thereby checking which shape into which a cue ball and an object ball are arranged on a straight line which is the same as a cue stick, and predicting the degree of thickness by which the cue ball moved during striking hits the object ball, such that even a beginner can easily understand billiards.
