Get accurate velocity measurements from your firearms in a wide range of shooting conditions with the Caldwell® Ballistic Precision Chronograph. This chronograph uses a high-speed 48 MHz processor along with a circuit that features an advanced data interface that allows each unit to be computer calibrated after assembly which allows for much better accuracy (+/- .25%) than other chronographs. A large LCD screen combines with an easy-to-use design that allows you to easily keep track of velocity in feet per second or meters per second. What’s more, this chronograph can also give you the shot string velocity data through the 15’ audio jack cable (included) to your smartphone or mobile device. Extra wide sunshades feature durable synthetic material construction and offer superior reliability on sunny days. Plus, a free app helps you easily keep track of your data and automatically calculates average velocity, standard deviation, min, max, and velocity spread for the shot string. This data can then be exported via email or simply pulled up for reference later. This chronograph measures from 5 to 9,999 FPS and comes with a ¼-20 threaded insert on the bottom of the housing for tripod mounting. Operates on a 9-Volt battery (not included). Order now!
