With daylight fading, keep the perpetrator in your sights with the Firefield® Nightfall 2x24 Night Vision Monocular. Featuring a powerful, built-in PULSE IR System infrared illuminator, this cutting-edge night vision device produces a crisp, clear image, perfect for use in security and general nighttime observation. The monocular is used with one eye only, allowing the other eye to maintain peripheral vision. Another advantage of this unit over a binocular is one eye is still adjusted to the dark while viewing, so operators are not debilitated with night blindness after using the night vision device. The Gen 1 image intensifier tube and multi-coated optics ensure a clear, bright image with detailed resolution. Featuring a modern, easy-grip design with a rubber-armored body and lightweight frame, the Nightfall 2x24 Monocular is built for durable, long-lasting operation. The unit is also water resistant, letting nothing stand in the way of your target.
