The BNVG II includes a Binocular Night Vision Device and a Clip-on Thermal Imager, or COTI, that attaches to the body of the BNVD with a bracket.
The night vision device amplifies the small amount of existing light emitted by stars, the moon's glow or other ambient light sources, and uses the light to clearly display objects in detail in very dark conditions, according to the release.
The COTI uses heat energy from the Marine's surroundings to add a thermal overlay which allows the image to be viewed more clearly. It can help identify potential "buried explosive devices, find hidden objects within foliated areas," the release states.
