The ATN Night Shadow CGT night vision binocular is a second generation night vision binocular built for heavy duty and medium range applications. ATN has also built a powerful infrared illuminator into this pair of night vision binoculars. Night vision binoculars collect and intensify ambient light for the user. If there is no ambient light to amplify, the ATN Night Shadow’s infrared illuminator will allow the user to see in complete darkness. In addition, the Night Shadow CGT has an automatic on/off sensor that turns the unit on when raised to viewing position, and off when lowered, leading to longer battery and product life. It is dark. You can barely see your hand in front of your face. You bring your ATN Night Shadow CGT Night Vision Device up to your eyes and turn it on. Suddenly, in green-hued clarity, the entire scene is like day.
