Older unit I really don't know anything about it. I bought it used years ago. It's very basic and simple. Only has 1 button/knob that powers it on and adjusts brightness. Looks like it has no magnification. Takes 2 AA batteries. They don't last very long. Couple hours maybe. Detail is lacking but I can see cows like 500 yards deer 300 or so. It works as it should. The front lens looks good but the back one has some scratches and body has some wear. I can't find any info on the model with a Google search and I really don't know how to price it so let's try $450 shipped. If you know anything about it feel free to comment. I think it was originally used for search and rescue. Thanks.
