Rangecraft Velocity PRO Radar Chronograph
Say goodbye to hoisting a chronograph on your barrel (and messing with your zero or harmonics), thanks to the Rangecraft Velocity PRO from Athlon Optics. This bad-boy uses Doppler radar to catch projectile speeds from 65 fps to 5,000 fps — suppressors, compensators, muzzle-brakes, goose-honks, it doesn’t care. 
Why you’ll want it in your range bag
Zero impact on your firearm setup: No mounting to the weapon = no tinkering with barrel harmonics or zero.
Handles every device you throw at it: Works perfectly whether your firearm is running a suppressor, compensator, or “what the heck is that mount” muzzle device.
Wide velocity range: From pistol loads to magnum rounds – 65 fps up to 5,000 fps. Athlon Optics
Built for the modern reloader or precision shooter: Collecting data, refining loads, fine-tuning your system? This is your tool.

Who it’s for
If you’re in the shop loading rounds, dialing in 6.5 Creed, .223, .308, or happy with handgun loads and want to log velocity reliably — this unit makes that quick, clean, and scientific. The discerning buyer who doesn’t want to eyeball “looks about right” but wants hard numbers.
