1. A method of determining a spin decay rate of a golf ball along a flight path, wherein the method comprises the steps of:

  • a. providing a launching device for launching the golf ball along the flight path at an initial speed and initial spin rate;

    b. launching the golf ball along the flight path at the initial speed and the initial spin rate;

    c. measuring a final spin rate at a final position spaced from the launching device, wherein the step of measuring further includes taking two images of the ball at the final position;

    d. timing the flight of the ball from the launching to the final position; and

    e. determining the spin decay rate using the images at the final position.
