One radar system tracks everything the club does before, during, and after impact - from commonly known parameters like Club Path and Face Angle to Swing Direction and Spin Loft. The other radar system tracks the full ball flight - from launch to landing and everything in between; including Launch Angle, Spin Rate and curvature.
TrackMan 4's Dual Radar Technology is a significant milestone in the evolution of Launch Monitor, golf instruction, coaching, fitting, and entertainment.
