See clearly even in the dark of night with the MO4-WPT night-vision monocular. Unsurpassed by competitors in the field, the MO4-WPT is made using ATN's white phosphor technology, which better detects the shades of intensity between white and black, resulting in improved contrast and depth perception. In fact, studies show that nighttime scenes appear remarkably more natural in black and white versus green, because black and white provides clearer information about contrast, shapes, and shadows. The unit is also equipped with ATN's cutting-edge "Smart" technology, which consists of a computerized proximity sensor, digital controls, and a long-range infrared illuminator. The proximity sensor will automatically turn the unit on and off when it's brought to the viewing position, helping save your battery life and the life of the unit itself. The digital controls, meanwhile, allow you to activate or deactivate all of the features of the MO4-WPT with a simple push of a button. And thanks to the powerful infrared illuminator, you can see even in total darkness with outstanding clarity. Additional details include multicoated all-glass optics, a super-fast 5x objective lens, and a nitrogen-sealed water- and fog-resistant housing. Camera-adaptable, the MO4-WPT carries a two-year warranty. 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 Night Vision Works
The monocular's white phosphor technology improves contrast and depth perception.
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.
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. 
The monocular includes easy-to-use digital controls for quick viewing.
