Forward Observation Unit

FOU3-Forward Observation Unit

Forward Observation Unit FOU-3 is an optoelectronic device used for general observation and positional awareness. It provides the user with positional data for both himself and his chosen target, using a built in laser rangefinder, personal GPS and a digital compass.

The device is equipped with a daytime camera and a thermal camera in order to ensure complete day/night usability.

The unit is designed to perform under harsh environmental conditions, as defined by military standards. Compared to its previous version (FOU-2), this device delivers an all-round better performance with higher customizability.
