The device is equipped with built-in infrared illuminator that allows the user to operate in total darkness.

The device can also be utilized as an excellent long-range viewer with optional 3X afocal and 5X magnifier lenses. The CR123/AA adapter is built into the battery compartment and requires only a single 3V CR123 or 1.5V AA battery for hours of night vision operation.
