A hit detection device for use in a marksmanship evaluation device for providing positive and negative reinforcement of shooting techniques immediately after each shot is fired. The hit detection device comprises a transducer spaced apart from a target member and detects and provides a hit indication output when the target is hit. In a preferred embodiment, the transducer in combination with electronic circuitry provide discrimination such that a hit indication output is only provided when the target member is actually hit by a projectile directly and no output is provided if the target is hit by a ricochet or is disturbed by any other external source such as the wind, sonic booms, etc. In a further preferred embodiment, the target member is three-dimensional and at least partially surrounds the transducer to shield the same from air pressure disturbances caused by projectiles passing by but not actually hitting the target member. |
