Description
R2A CHRONOGRAPH
With the R2A Chronograph, you can measure the projectile velocity of your firearm or airgun. Moreover, it is loaded with all the features you need in a compact, durable design.
A ballistic chronograph or gun chronograph is a measuring instrument used to measure the velocity of a projectile in flight. You typically use it to determine the speed of a bullet or pellet fired from a firearm or airgun.
It is powered by either alkaline or rechargeable batteries, which are not included. Because of this power source, you can take the unit with you. Use it in the field or at the range or in the comfort of your own home.
Not only can you measure velocities in meter per second, but also foot per second. Furthermore, you can record minimum and maximum velocities, as well as absolute velocity. The chronograph even measures kinetic energy in either Joule or foot pound energy. Additionally, you get specialized measuring features, like standard deviation and rate of fire.
