The modern Chronograph consiss of two sensing areas that detect the movement and passage of a bullet. The Chronograph screens detect the time it takes for the bullet to pass between the two screens. Knowing the distance between the screens and the time it takes allows the chronograph to calculate the speed of the bullet or pellet.
