Abstract
A toy gun or similar device usable with reflective target apparatus utilizes a pulsed light source and a self-contained light detector for detecting light reflected from the target apparatus back to the light detector. The gun includes an audible indicator responsive to the light detector for indicating each time a "hit" is made on the target apparatus, and also includes a resettable counter that provides an indication of the total number of such "hits" achieved in a given time period. The invention also provides a target having a pulsed light source to energize or actuate the light detector.
