Chronographs

Chronographs

Balistic speed meters (also called Air Chrony or chronograph) are devices for measuring the power of an airsoft gun. Performance can be measured by using two indicators, namely the muzzle velocity in either m/s (meters per second) or fps (feet per second) and the projectile energy measured in Joules. Some airsoft chronographs can also measure shot cadence and can be connected to computers and other devices via USB cable or Bluetooth.

Chronographs are especially useful for pro airsoft players who tend to upgrade their guns by replacing internal components and mechanisms with more powerful ones (so-called upgrading or tuning). After upgrading their airsoft gun, they can check the performance and compare it with the performance before the upgrade.
