BLUE CHRONO

PepperBall projectiles specified velocity range is 300-350 feet per second. The only way to determine if your agency launchers are within operating spec is to test them on a radar chronograph. The Blue Chronograph is the industry standard for accurate velocity testing. This new version is smaller, more portable and easy to use. Launchers should be velocity checked at least once a year (and whenever performing service on them) and written records should be kept for liability purposes. This chronograph is a workhorse and will still be in use long after you've retired.
