ProChrono LTD Ballistic Chronograph

The ProChrono LTD Ballistic Chronograph by Competition Electronics Inc. is a precision velocity measurement instrument designed for shooters who demand accurate ballistic data. This compact chronograph measures the muzzle velocity of projectiles from firearms, shotguns, airguns, and paintball markers, providing the quantifiable feedback necessary for load development, ammunition testing, and performance verification. The unit delivers verified velocity readings essential for understanding terminal ballistics and optimizing firearm performance across multiple calibers and platforms.

The CEI-3825 ProChrono LTD features refined internal and external circuitry with an updated enclosure design that improves durability and measurement consistency. A full-featured operating system provides multiple data capture and display modes, allowing operators to record single shots, strings of fire, and statistical analysis across rounds. The chronograph measures 5.45 × 2.5 × 17.95 inches and weighs 2.49 lbs, making it portable for field deployment. The unit operates on a single 9-volt alkaline battery (not included) and is fully equipped for outdoor use. For indoor range applications, the optional Indoor Lighting System (part# CEI-4100) enhances sensor activation in low-ambient-light environments.

This chronograph serves ammunition manufacturers, handloaders, precision rifle competitors, law enforcement firearms trainers, and military armorer communities who require empirical velocity documentation. Ballistic chronographs provide the objective data necessary to verify ammunition performance, confirm barrel velocity stability over time, and detect performance degradation caused by wear or environmental factors. Range training programs use velocity confirmation to validate duty ammunition performance and detect anomalies that may indicate quality-control issues with ammunition lots.

The ProChrono LTD occupies a practical middle ground in the chronograph market—more capable than entry-level models, yet compact enough for mobile range operations and field ammunition testing. Competition Electronics maintains a reputation for reliable velocity measurement across diverse shooting disciplines, and the LTD series represents the refinement of that design through updated manufacturing tolerances and firmware improvements. Velocity data from this unit integrates into ballistic calculation software, trajectory prediction tools, and load development spreadsheets used by precision shooters and ammunition developers.
