I bought this device by Yukon several weeks ago and it is really great! The image is very nice though you cant expect much from gen.1. But the performance (battery is long-lasting) is absolutely fantastic. Moreover, the price is more than affordable.

I was really surprised how sharp the images are and overall how well this works. The built in IR light works very well, though of course the effective range is limited to 20 feet or so. I've used this mostly on Lake Erie both hand held and attached to a C 130 telescope. Boats traverse at night, sometimes with lights sometimes not. Always curious, this thing really reaches out. At distance the images aren't quite as crisp, but I'm satisfied. Also used it to identify night critters in the garden.
