Shooting Chrony's Beta-Chrony Chronograph gives you exact ballistics at an affordable price. Check velocities ranging from 30 fps to 7,000 fps to within 0.5% accuracy for any projectile, including arrows, bullets, pellets, etc. An LCD read-out stays on the screen until the next shot is fired. The Beta-Chrony features a 60-shot memory (divided into six strings of 2 to 10 shots each). Each string gives you Hi, Lo and Average velocity, ES and SD. It also features a permanent memory for at-home data retrieval. Constructed with a steel housing for strength, durability, and less expansion/contraction deviation than plastic housings. Weighing in at under a lightweight 2.5 lbs., the Beta-Chrony folds for safe carrying and storage. A manufacturer's three-year warranty is included.
