A Swing Analyzer is a tool used primarily in sports, especially in golf and baseball, to assess and improve a player's swing technique. It typically uses sensors or cameras to capture the motion of the swing, providing detailed feedback on aspects like speed, angle, and timing. This data helps athletes understand their performance and make necessary adjustments. These devices can be standalone gadgets or integrated into training software, often connected to smartphones or tablets. By analyzing swings, players can enhance their skills, reduce the risk of injury, and ultimately improve their game performance. Popular brands include TrackMan and Zepp.
