I have one I keep on my 7mm-08.
I have a feeder I can watch out that window in my cabin.
I have a motion detector set up out there on it and I
sometimes sleep out there, so I can wake up and shoot
a hog when they come in.
It works...I use that NV to look first then if I want to shoot
They don't usually have much reaction to it.
It's good out to 200 yards or so.
I would much prefer thermal but I just haven't got one yet.
