Competition Electronics ProChrono

The ProChrono is designed for both indoor and outdoor use. If you are using it indoors, ensure you have adequate lighting, as the sensors rely on detecting the projectile's shadow as it passes over the skyscreens.

It runs on a single standard 9-volt alkaline battery. It is a simple, low-power design that makes it easy to keep running during long range sessions.

It is fully compatible with archery equipment, as well as firearms, shotguns, airguns, and paintball markers. Its versatile design is built to capture velocity readings across a wide variety of projectile types and speeds.

The setup is straightforward and requires no complex calibration. You simply place the unit on a tripod or stable surface, attach the skyscreens, and it is ready to measure your velocity.

While newer models may offer Bluetooth connectivity or smartphone integration, the ProChrono focuses on the core fundamentals of velocity measurement. It is a time-tested, reliable tool that prioritizes consistent, accurate data over extra digital features.
