Product DescriptionThe Athlon Rangecraft Velocity Pro Radar Chronograph makes collecting reliable muzzle velocity data fast and simple. Using Doppler radar detection, it measures projectile speed without mounting anything to your firearm-helping preserve your zero and avoiding changes to barrel harmonics. Because it does not rely on muzzle blast, it works well with suppressors, muzzle brakes, compensators, and other muzzle devices. A bright 2.4-inch display and long battery life make it ideal for extended range sessions across a wide range of shooting disciplines.Product Highlights Doppler radar chronograph captures projectile velocity without attaching to the firearm Wide velocity measurement range from 65 to 5,000 feet per second (FPS) Compatible with suppressed firearms and common muzzle devices (not triggered by muzzle blast) Easy-to-read 2.4-inch display for quick, at-a-glance range data Compact, lightweight design with 6+ hours of runtime for long range daysSpecs Brand: Athlon Product Type: Radar Chronograph Model: Rangecraft Velocity Pro Velocity Range: 65-5,000 FPS Supported Projectile Diameter: 0.17-0.50 in (as listed: ".17-50" diameter) Display: 2.4 in Battery Life: 6+ hours Battery Type: Rechargeable lithium-ion (internal) Weight: 4.7 oz MPN: 707301 UPC: 813869024915Disclaimer: We strive to provide accurate and up-to-date product descriptions, specifications, and images; however, errors or omissions may occasionally occur.
