Trackman is a high-tech radar system that is often used by golf professionals and serious amateur players to measure and analyze various aspects of their golf swing and ball flight. It is considered to be a very useful tool for practice because it provides precise and accurate measurements of a wide range of variables, such as clubhead speed, ball speed, launch angle, spin rate, and carry distance.
By analyzing this data, players can identify areas of their swing that may be causing them to hit poor shots, and make adjustments to improve their performance. Trackman can also be used to compare the performance of different clubs in a player's bag, helping them to choose the right club for different shots and situations on the course.
Overall, Trackman is highly regarded in the golf community as a valuable practice aid, because it allows players to gain a deeper understanding of their swing and ball flight, and make more informed decisions about how to improve their game.
