Brownells Brownells Brownells 75th Anniversary - A Shooting Heritage

Gives Accurate Analysis Of Ammo Performance

The Pro Chrono is a compact, full-featured chronograph that accurately measures velocity readings from 22 to 7,000 feet per second. Lets you record up to 9 strings of 99 shots each and then review the data to find average velocity, standard deviation, and extreme spread. The optional PC USB Interface kit has everything needed to control all of the chronograph functions from your Microsoft Windows-based computer, so you can list velocity strings, compute ft./lbs. of energy, power factors, and even create graphs for easy data comparison and interpretation. The unit is extremely light and portable and comes with ¼"-20 threads in the base for easy mounting to a standard camera tripod.
