Bought (used) ANVIS-6 Gen3 Night Vision. What's left to say? They're AWESOME!
Here are a few pictures I took at 3:00am when the dogs decided they wanted to go outside. Picture 1 is looking across the field (from my deck) to the open eye. Picture 2,3 and 4 are taken from the same location but with me holding the ANVIS up to the camera.
The animals in picture 3 are my 2 GSD's, 1 is sniffing around and the blurry one is running toward the deck. You really can't appriciate how awesome these things are until you stand in the darkness and see nothing vs looking through the ANVIS and suddenly see everything!
