Abstract

An electronic sighting device and method is described for calibrating a shooting device. The sighting device includes a display screen, mounting clip, optical lens, and an external infra-red torch for light compensation. By one discharge from the shooting device, the adjustable targeting reticule of the electronic sighting device can be set to align with the targeting position. The alignment process does not require adjusting the optical lens position, nor the mounting position of the sighting device.
