ATN Gen 2+ Night Arrow 2-2 Night Vision Weapon Sight Specifications


The Night Arrow 2-2 is a rugged night vision weapon sight that allows you to confidently observe your prey, acquire the target, and aim. As a result, the 2x magnification sight is an ideal choice for the demanding hunter or sports shooter. The sight is outfitted with a "red on green" reticle system, with an illuminated red center crosshair that provides optimal contrast against the green night-vision background. The reticle makes it possible to identify and lock on targets even in complete darkness. The sight also offers an automatic brightness control (ABC) to protect the tube, along with a single knob for easy operation. And thanks to the rugged, nitrogen-sealed housing, the sight is water- and fog-resistant. The lightweight, compact sight--which mounts to standard weaver rails--operates on a single AA battery and carries a limited two-year warranty.



The Night Arrow's "red on green" reticle system lets you lock on targets in complete darkness.
How Night Vision Works
All ATN night vision devices consist of several main parts: an objective lens, an eyepiece, a power supply, and an image intensifier tube (photocathode tube). The devices function by gathering existing ambient light, such as starlight, moonlight, or infrared light, through the front lens. This light, which is made up of photons, goes into the photocathode tube and is converted into electrons. Next, the device amplifies the electrons to a much greater number through an electrical and chemical process, and then hurls them against a phosphorous screen that changes them back into visible light. The image will appear through the eyepiece as a clear, black-and-white or green-hued, amplified re-creation of the scene you were observing.

All night vision devices need some light to amplify. That's why all ATN night vision devices have a built-in infrared illuminator (IRI). An IRI essentially throws out a beam of infrared light that is near invisible to the naked eye, but your night vision device can see it. This allows you to use your scope even in total darkness. The IRI works like a flashlight, which is why the distance you can see with it is limited. Although ATN IRIs extend out to 100 yards, the IRI may cover only 40 to 60 percent of the viewing area.

How Far Can You See?
There are many different variables that can affect the distance you see with a night vision device. First, what are you trying to see? Are you looking for another boat on the water or are you looking for a rabbit in the woods? The larger the object, the easier it is to see. Plus, are you trying to see details (commonly called "recognition range"), or are you just trying to see if something is there? Maybe you will see just the movement, but won't be able to determine 100 percent who are what it is. This is called "detection range." Another variable is lighting conditions. The more ambient light you have, the better and further you will be able to see. You can always see further on a night where the moon and stars are out than if it's cloudy and overcast. ATN typically states that you can tell the difference between a male and female or a dog and a deer at about 75 to 100 yards. However, if you were looking across an open field and there was a half moon out, you could see a barn or a house 500 yards away.
