protraer is incorrectly written, and should be written as "protracer" as meaning:
protraer = protracerProtracer is responsible for that see the trajectory of the ball as a line of color on our television screen. Perhaps there is not many people who know but the Protracer isn't a radar such as the FlightsScope or the TrackMan system; It is an ultra-sensitive camera, connected to a powerful computer system, which is able to identify in each frame of the retransmission golf ball. That is why you can show clearly, for example, how wind affects the ball since it is not simulating the flight on the basis of data obtained during the impact but it is following its trajectory in real time.
