ABSTRACT:
A plurality of targets comprise two spaced metal screens secured in electrical isolation. A voltage is applied to the screens such that when the screens are shorted by a penetrating metal projectile, a pulse is produced having a pulse duration representing a particular type of projectile according to the length of the projectile. A logic circuit including a counter produces a count signal representing the pulse duration and applies this count signal to a CPU which compares the count signal to stored time intervals to produce a projectile identifying signal which is applied to a LCD display for describing the type of projectile hitting the target. A target signal generator generates a signal representing any one of the targets hit in response to a hit on that one target and supplies that signal to the CPU which generates a display signal identifying the target descriptively.
