Abstract

Apparatus for acquiring data for configuring a pneumatic air gun comprises a data storage device and a controller. The controller is configured to determine a required velocity for a firing and determine a pressure of an air reservoir, or a pressure in an air flow path at a position downstream of the air reservoir of the gun. The controller is configured to determine a value of a valve activating parameter for the firing and determine a measured velocity of a projectile fired from the gun using the determined value of the valve activating parameter. The controller is configured to determine whether a difference between the measured velocity and the required velocity is within a required limit. The controller is configured to store the determined pressure and the determined value of the valve activating parameter in the data storage device as mapping data for configuring a future firing of the gun when the difference between the measured velocity and the required velocity is within the required limit.
