Abstract: A system for scoring targets with a control module and plurality of timer modules connected thereto. The control module generates start and stop signals and the timer modules count the number of hits on one or more targets and the time required to make an adjustable number of hits. Each hit is detected by an electrooptic sensor. The start signal can be generated by a sound, by a pseudo-random generator or by manual switch operation.

Abstract: An optical apparatus adapted for insertion into the open end of a hand-gun barrel. A piezoelectric crystal produces an output signal in response to the hammer impact to cause an LED to be intermittently operated by an oscillator powered by batteries and produce pulses of light which are directed by a lens onto a target. The oscillator is also coupled to a counter which is reset by the crystal output and which disables a gate between oscillator and LED upon a first count and enables a gate connecting the counter reset to the crystal upon a second count.
