Snooker Eight-Ball Sight Corrector sightrigh

Usage 1: After getting into position, ensure that your feet are on the line, your body is sideways, your arm, wrist, and grip are all in line with the straight lines on the tool. If you are standing crooked, the top and bottom lines on the tool will be broken. Adjust multiple times until you can consistently line up with the tool's lines each time you get down.

Usage 2: You can first position the 5-point position, place the cue ball in a straight line, then place the tool directly behind the cue ball, and then set up the rest. Observe whether the cue can be aligned with the tool in a straight line. If it can, then continue to use the cue to strike the ball. Repeat this practice many times. After using it for a while, you can correct the parallax error and form a correct visual aiming habit.
