Untitled document If what you need is a hands free night vision, we at ATN have the unit for you. We would like to introduce you to the ATN Viper modular goggle system. Designed primarily to be a goggle system for hands free application, this unit can also be used as a compact monocular or can be attached to a camera for night time photography. This high resolution 1st Gen.+ night vision unit comes with 1x magnification, but has the option of being 4x or 8x. Surprisingly, even though we gave the Viper a heavy coated glass lens, we were still able to keep its weight down to only nine ounces. So for any activity you plan on doing which requires night vision and hands free operation, the Viper delivers superior results.
