Bullet velocity is a critical measurement for long range precision shooting. Knowing the velocity from ones own rifle is necessary to calculate long range trajectories accurately. The variation in muzzle velocity is a key metric for estimating dispersion of the cartridge at long range. The Xero C1 is among the best personal chronographs we have tested and highly recommend it to all long range and precision shooters.

The Xero® C1 Pro chronograph makes ballistics calculations easy. This compact device fits in your back pocket, measures projectile velocities from 100 fps to 5,000 fps and provides the data you need to refine your equipment. Setup is simple and intuitive, thanks to the button-operated design. Compare velocity for every shot fired, track deviation and more in the ShotView™ smartphone app. It’s built to last, thanks to its IPX7 water-resistant rating. With battery life for 2,000 shots or up to 6 hours, you’ll have plenty of time at the range.
