Athlon Optics Rangecraft Velocity Pro Radar Chronograph w/

Product Overview

The Athlon Optics Rangecraft Velocity Pro Radar Chronograph delivers lab-grade ballistic precision in a compact, field-ready package. Designed for shooters who need reliable velocity data without compromising their firearm’s performance, this non-invasive chronograph uses advanced Doppler radar technology to measure projectile speeds from 65 to 5,000 feet per second with a remarkable +/- 0.1% accuracy. Whether you’re working with high-powered rifles, pistols, airguns, or archery equipment, the Velocity Pro captures consistent, repeatable data without mounting hardware on your barrel—preserving barrel harmonics and maintaining your zero. Its standalone placement beside the firearm eliminates interference, making it ideal for precision shooters who rely on unaltered mechanical performance. With integrated Bluetooth connectivity and a dedicated mobile app, the Velocity Pro streamlines data collection, analysis, and long-term tracking, turning raw speed readings into actionable ballistic insights. Built to endure real-world range conditions, it’s a tool engineered for both casual shooters and dedicated reloaders who demand accuracy without compromise.

Key Features

• Doppler Radar Precision – Measures projectile velocity using non-contact Doppler radar, ensuring your barrel remains untouched and your zero stays intact. Accurately captures speeds between 65 and 5,000 FPS with a margin of error of just +/- 0.1%, providing trustworthy data for load development, ballistic tuning, and performance validation across firearms and archery systems.
• Advanced Session Management – Stores up to 50 individual shooting sessions, each capable of recording up to 100 shots. On the device’s 2.4″ LCD screen, you can instantly review key metrics including average velocity, standard deviation, and extreme spread. If a shot needs to be excluded—such as a flyer or misfire—simply hold the “DEL” button during the session to remove it from the data string without interrupting your workflow.
• Seamless App Integration – Pairs wirelessly via Bluetooth with the Athlon Ballistics Lite app, available for both Android and iPhone. Sync all shooting sessions to your mobile device for deeper analysis, where you can rename sessions, exclude specific shots from calculations, and link data to custom rifle and bullet profiles. This enables organized, long-term tracking of performance across different firearms, loads, and shooting conditions.
• Field-Ready Durability – Weighing only 4.7 ounces and rated IP67 for waterproof protection, the Velocity Pro is built to perform in demanding environments. Its compact, rugged design makes it easy to transport and set up at the range or in the field, while the large, high-visibility LCD screen ensures clear readability in bright sunlight or low-light conditions.
• Intuitive, Versatile Operation – Designed for quick setup and ease of use across multiple platforms. Start a new session in seconds for rifles, pistols, airguns, or archery. During session creation, input your projectile weight to automatically calculate Kinetic Energy and Power Factor—adding valuable ballistic context to your records with minimal effort.

Benefits & Use Cases

The Velocity Pro is an essential tool for reloaders aiming to develop consistent, high-performance ammunition. By providing precise velocity data without altering the firearm, it enables shooters to fine-tune loads while maintaining mechanical integrity. Competitive shooters benefit from real-time feedback on shot consistency, helping them adjust for optimal scoring and reliability. Airgun and archery users gain valuable insight into pellet and arrow performance, allowing for better equipment selection and tuning. Hunters can verify bullet velocity to ensure ethical shot placement at varying distances. Its non-invasive design is particularly valuable for precision rifles, where preserving barrel harmonics and zero is critical. The combination of on-device storage and app-based management supports comprehensive ballistic profiling across multiple firearms, loads, and shooting scenarios, making it a versatile addition to any shooter’s toolkit.

Important Notes

The Velocity Pro requires a clear line-of-sight to the projectile and must be positioned beside the firearm—not mounted on it. Ensure the radar beam path remains unobstructed during firing to maintain accuracy. The Athlon Ballistics Lite app must be downloaded separately and is compatible with most modern Android and iOS devices. Always check local regulations regarding electronic devices at shooting ranges. The package includes the Velocity Pro chronograph only; mounting accessories, tripods, or other supports are sold separately and not included.
