Athlon Radar Chronograph 2.4" Displayathlon Rangecraft Velocity Pro

The Athlon Rangecraft Velocity Pro radar chronograph is a Doppler-based ballistics tool built for shooters who need fast, accurate velocity data without the fuss of traditional chronographs. Unlike light-based systems, the Velocity Pro uses radar technology to track projectiles in flight, which means you can mount it downrange and away from your rifle—no zero shifts, no barrel harmonics disruption, and no sensitivity to muzzle devices. Whether you're running a suppressor, compensator, or shooting unsuppressed, this radar chronograph reads your shots cleanly.

The 2.4-inch LCD display is bright and readable in sunlight or shade, and the intuitive interface lets you cycle through velocity metrics—average, extreme spread, standard deviation, kinetic energy, and power factor—with a quick button press. The Velocity Pro captures data across an impressive range of calibers and projectile types: rifles, pistols, airguns, and even arrows, all between 65 and 5,000 fps. It stores up to 50 range sessions with 100 shots each, so you can build a library of load data and track performance over time.

Built for serious field use, the chronograph is IP67 waterproof, weighs just 4.7 ounces, and runs on a USB-C rechargeable lithium-ion battery good for 6+ hours—longer than most range trips. Pair it with the Athlon Ballistics Lite app to tag sessions to your rifle profiles, review historical data, and dial in ballistic solutions for extended-range shooting. The included tripod mount (1/4-20 thread) lets you stabilize the unit for consistent readings.

This is a tool for handloaders, long-range hunters, and precision shooters who want reliable velocity baseline data without the setup headaches of traditional chronographs.

Frequently Asked Questions

Will the Velocity Pro work with my suppressed rifle or muzzle brake?

Yes. The radar-based design isn't triggered by muzzle blast, so suppressors, brakes, compensators, and other muzzle devices don't interfere with velocity readings. This is a major advantage over light-based chronographs, which can struggle with reduced light around muzzle devices.

Do I have to mount this on my rifle?

No. You can mount it downrange on a stable surface (tripod) or hold it in position away from your rifle. Since it uses radar to track the projectile in flight, it doesn't need to be attached to your gun, which eliminates zero shifts and barrel harmonics issues.

What calibers and projectile types does it measure?

The Velocity Pro reads projectiles ranging from .17 to .50 caliber at velocities between 65 and 5,000 fps. This covers rifles, pistols, airguns, and archery.

How long does the battery last, and what comes in the box?

The rechargeable lithium-ion battery provides 6+ hours of operation per charge—typically longer than a full range session. The package includes a USB-A to USB-C cable for charging. A tripod is also included with a 1/4-20 thread mount for stable setup.

Can I use this with the Athlon Ballistics app?

Yes. The Athlon Ballistics Lite app lets you manage your range sessions, tag data to rifle profiles, review historical velocity records, and use ballistic calculations to extend your shooting range. The chronograph connects via Bluetooth and can also receive firmware updates wirelessly.
