A device for electronically and optically counting objects, such as fish, animals, vegetation or other materials, as they are placed into a container. The device surrounds a defined opening on a container. As objects are placed into the container, they fall through the frame of the opening. A light source, such as a laser or LED, is directed toward a light detector in such a way as to be disrupted as the animal falls into the container. A light detector detects said disruption of the light and signals the electronic circuit to add to the number previously counted. Various methods of communicating the count are provided. The preferred method of communicating the count is via an integrated visual display. The preferred method of powering the device is by the use of one or more electric battery. Various methods of electrically powering the device are provided.
