The rangemeter is a digital time-interval counter that displays range when coupled to the XM23 Laser Rangefinder. It receives start and stop pulses from the rangefinder and displays range readings from 200 to 9995 m. The total volume of the rangemeter is less than 18 cu. in. The readout is made of the electroluminescent material, and optical coupling is used between the computing circuits and the photoconductive readout matrix. Author
