There is a real good source for night vision optics at http://www.nightvisionexperts.com/ I was graciously allowed several product returns in the process of finding the right binos for me. The best variety is there for sure. I got the "Shadow" ATN's Gen2 set. Extremely happy with the High Resolution Imaging and the unit has a camera and video adapter. Impact resistant. One Million Candlepower Infrared Spotlight along side these babys lights up the night like a fireworks display! "Defender 6800" Gen3 Nightscope is the other choice. Made in USA with a 2 year warranty. Tubes and optics have best water/moisture resistance I have seen. (er...I mean..not seen)
