Looking for a full-featured chronograph at an affordable price. The ProChrono LTD ballistic chronograph offers all the on-board features and accuracy of our DLX model, minus Bluetooth connectivity. This new generation of the popular ProChrono model, based on a time-tested design, has been reliably measuring "almost anything that shoots" since 1985. It's perfect for firearms, shotguns, archery, airguns and paintball. The ProChrono LTD includes everything needed for outdoor use, making it a versatile tool for measuring projectile speed. For indoor use, we recommend adding our optional Indoor Lighting System (part# CEI-4100) for optimal performance. The chronograph requires a single 9V alkaline battery (not included) for operation, offering a cost-effective solution for precise velocity measurements.
