F-1 CHRONY - The very first model and still typically the most popular. Provides numbered shots and velocities plus high, low and average velocities from the string. All Chrony models are powered with a single 9V battery and may easily be mounted on a 1/4"-20 tpi camera tripod for fast, easy set up. The Chrony is simple to make use of, just unfold, set the sky screens in position using the diffusers, switch on the switch and start shooting.
Shooting Chrony chronographs measure the velocity of almost any projectile, including pellets, steel BBs, plastic and metal airsoft BBs, bullets, shotgun pellets and slugs, arrows, bolts, darts, paintballs and just about any other projectile that fits through the skyscreens (which are the upright structures in the image). Shooting Chrony chronographs measure speed (feet per second and meters per second) from 30 fps to 7,000 fps with more than 99.5% accuracy.
