Awesome scope - Armasight Predator 336 2-8x25mm Thermal Imaging Rifle Scope

I bought this to help control the varmint population on my small farm. So far it has impressed me. Avg range of my shooting is from 50 to 200 yards. On 4 power at 200 yards targets are easily distinguishable but surrounding area is grainy. No magnification everything is crisp and clear. My only complaint would be the instruction manual that comes with it. Not clearly written and apparently the printer must have been low on ink because several pages are unreadable in places. I was able to figure most of its functions out on my own and what I couldn't I youtubed it.
