New for 2025 Athlon makes ballistic calculations easy with the Rangecraft Velocity Pro Radar Chronograph. It picks up the projectiles via Doppler radar thus eliminating the need to mount the Rangecraft Velocity Pro to the weapon. This means it wont affect your zeroing or barrel harmonics so your accuracy remains the same. Since the unit isnt triggered by a muzzle blast it can pick up on projectiles from firearms with suppressors muzzle breaks compensators and other muzzle devices. The Rangecraft Velocity Pro can measure projectile velocity between 65 fps and 5000 fps allowing users to measure the velocity of a massive assortment of projectiles.
