Golf is a game in which the ball is stopped on the course by hitting the club and put it in the designated hole to compete for the best. These golf swings can be divided into driving shots made of long clubs such as drivers, pitching made of short clubs such as irons, and putts made of putters. In order to send the ball the desired distance in the desired direction in the swinging motion using the club, it is necessary to match the correct hit angle, the correct hit point, the exact hit strength, the correct hit strength and the swing trajectory.

The most basic swing technique, on the other hand, is the square impact and the flat swing track approaching the target line. Here, the square impact means that the club face is perpendicular to the target line connecting the ball and the target at the moment of impact, and the flat swing trajectory means that the club face reaches the impact point with respect to the extension line of the target line connecting the ball and the target. It means the incident at the same angle (incidence angle) and follow-throw at the same angle (reflection angle) after impact.
