ABSTRACT Apparatus for rating hits on a target comprises two photoelectric detector systems . One of said systems is held in position adjacent to the path of travel of a target and is used to measure the distance from an entry hole to the center of the bull's eye of the target in the direction in which the target travels through the apparatus. The other system is mounted on a cross slide , which is movable at right angles to the direc- tion of travel of the target and measures the distance from the center of the entry hole to the center of the bull's eye in that transverse direction. The two distance vectors are vectorially summed up by a vector computer and are multiplied with a calibration factor. The result of the measurement may then be displayed, printed or delivered to an electronic data processing system in the form of a tenth-of-a-ring rating.
