摘要:
A billiard aim instruction kit for pocket billiards. A position reference tool is placed at locations on a pocket billiard table surface and aligned aiming toward a pocket. A marking powder packet is used to mark each location. The position reference tool is then removed to reveal each location's aiming point reference mark, 5 object ball position marks, 5 aiming angle reference marks and a center hit cue ball direction reference mark. An object ball is centered on the 5 object ball position marks of each location marked and rail indicators mark the rail for cue ball direction. The student shoots the cue ball from one of 5 different aiming angle reference points a multiplicity of times without further marking procedures. After each shot the student receives feed back as he compares results with the rail indicator and graphics on the position reference tool.
