Abstract
An apparatus is disclosed for sensing the impact of a projectile. The apparatus includes a target which is a bladder having a predetermined normal volume which is reduced in size upon impact by a projectile. The bladder has an outlet in communication with atmospheric air for providing an escape for a pulse of fluid from the bladder when the bladder volume is reduced in response to impact by a projectile. Resilient foam is disposed within the bladder urging it toward its normal volume after impact by a projectile. A sensor is connected to the bladder for sensing a pulse of air escaping from the bladder.
