The night vission devices I used made the world look like a 1940/50s TV picture.
I’ve got a 1st Gen. hand held scope that is tolerable in an open field for about 100 yards. Worthless in the woods though.
Buddy has a 2nd Gen set of Russian googles that are phenomenally better. We used them beach camping one night to find a guy at the beach who wandered up into the dunes and passed out drunk.
