Shooting Chrony's Beta Master Chrony combines all of the features of their Beta-Chrony chronograph with a remote read-out-monitor that also functions as a remote control. Review data, delete shots or whole strings, move to another string or return to a previous string and continue where you let of, etc., all from a distance. 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. Features a 60-shot memory (divided into six strings of 2 to 10 shots each). Each string give 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.
