If a hands-free Night Vision Goggle System is what you need, ATN has the unit for you. Viper Night Vision Goggles are designed primarily to be a goggles system for hands-free application, but this unit can also be used as a compact monocular or for nighttime photography when attached to a camera. This high-resolution 1st Generation.+ Night Vision unit comes with 1x magnification, but can be optional 4x or 8x. Surprisingly, even though they gave the Viper a heavy coated glass lens, they were still able to keep its weight down to only nine ounces. For any activity which requires night vision and hands-free operation, the ATN Viper delivers superior results.
