Introducing the latest version of Competitive Electronics' ProChrono model - a product that has been measuring "almost anything that shoots" since 1985. It is suitable for use with firearms, shotguns, archery, airguns, and paintball and comes with everything required for outdoor use. For indoor use, it is recommended that users purchase the optional Indoor Lighting System (part# CEI-4100). The only item required for operation is a 9 volt alkaline battery, which is not included.

This latest version incorporates internal and external refinements, including circuitry updates and enclosure design improvements. It has a built-in operating system that is full-featured and comes with multiple shot string memory and statistics. The sensing system is compatible with a wide variety of light conditions and projectiles, and the internal shot clock is much faster than previous models, ensuring an improved accuracy to +/- .5% or better.

It comes with a two-year warranty against defects in materials and workmanship. In addition, if required, it also has a 1/2 price repair guarantee.
