All airsoft fans know the rules and restrictions according to which players can only use airsoft guns of a certain velocity and muzzle energy. Those indicators cannot be checked by eye and you need a special device to check them. The app works in conjunction with the Airsoft Pro Sensor, which is an electronic chronograph. The BB pellet departure speed, rate of fire, RPS, and the total number of BB pellets are transmitted to the screen of your smartphone in real-time and saved into the History section for further analysis. The dynamics of changes in indicators can be tracked in the Statistics section and the operating modes of the Airsoft Pro Sensor can be easily changed on the Settings screen. Now it is much easier and more interesting to check your airsoft gun for compliance with the airsoft rules.
