Description
Doppler radar chronograph with a 2.4" display, for measuring muzzle and downrange velocity.
The RangeCraft Velocity Pro is a point-and-shoot Doppler radar chronograph that measures projectile velocity from 65 to 5000 FPS with ±0.1% accuracy, without needing to be positioned in front of the muzzle. Its radar tracks the correct shot even with multiple shooters firing nearby, and results are shown on a bright 2.4" transreflective LCD screen readable in daylight.
An intuitive interface switches between average velocity, standard deviation, extreme spread, deviation from average, kinetic energy and power factor, and sessions can be reviewed later or synced to the Athlon Ballistics app over Bluetooth. A rechargeable battery and IP67-rated housing make it suited to a day at the range in most weather.
Key features
- Doppler radar sensing — point-and-shoot operation with no muzzle-mounted unit.
- Multiple-shooter tracking — identifies the correct shot when others are firing nearby.
- 2.4" transreflective LCD screen — 240 x 320 resolution, readable in daylight.
- Intuitive interface — quickly switches between average velocity, standard deviation, extreme spread, deviation from average, kinetic energy and power factor.
- 50-session memory — stores up to 100 shots per session.
- Athlon Ballistics app compatible — connects over Bluetooth, with firmware updates delivered the same way.
- Rechargeable lithium-ion battery — approximately 6 hours of runtime, charged via USB-C.
- IP67 waterproof housing — sealed against dust and temporary immersion.
Typical applications
- Handloading and ammunition development
- Rifle, pistol, archery, air gun and other velocity testing
