GEHMANN 173 AIRGUN CHRONOGRAPH

The 173 Ballistic Chronograph is a compact, precision instrument designed to measure the velocity and kinetic energy of air rifle ammunition. It’s also capable of reading small-calibre firearm rounds, though repeated use with powder-based ammo may lead to residue build-up and eventual malfunction. Ideal for airgun shooters seeking accurate, in-depth ballistic data, it offers an array of measurement functions and data outputs.
