Yukon Night Vision Binoculars and night vision goggles are built with versatility and comfort in mind. The Yukon Viking series of NV Binoculars features rubberized housings, with ergonomically designed bodies that are surprisingly lightweight and can be taken on long expeditions both easily and comfortably. These Yukon NV Goggles utilize the revolutionary Eclipse Lens Cover System, with flip-up covers that can be easily clipped back against the body of the binoculars and rotated out of the user's viewing area while eliminating lens cap hassles. Pin holes in the lens caps allow the Yukon Night Vision Binoculars to be used in the daytime when the caps are closed. Yukon Night Vision Goggles provide clear viewing in total darkness by utilizing a built-in IR infrared illuminator; when in use, the illuminator emits a pulsing frequency that is so energy efficient it creates less battery drainage and prolongs battery life.
