Caldwell Chrono Premium Kit
The kit includes a chronograph, an IR LED lighting set, a tripod and a special carrying case. By using a 48MHz high-speed processor and an advanced data interface, the chrono is able to offer higher accuracy (+/- 0.25%) than other chronographs. The speed is displayed on a large LCD screen and can also be sent to a smartphone via an audio cable. A free app is available for download that records the velocity of each shot and automatically calculates the average velocity, standard deviation, min, max and velocity spread. The chronograph measures from 5 to 9,999 FPS and runs on a 9 volt battery.
