Works great for spotting hogs up to 500 yards.
I think in all fairness, you need to qualify "spotting hogs up to 500 yards".
I have a 70mm/60hz Thermal monocular and I can't spot a hog at 500 yds. I can see it's a moving warm something out there, but not good enough to qualify hog from small cow or hog from large warm rock, pile of warm cactus, etc.
The TK (I could not find a TKS) states "helps you see people, objects and animals over 100 yards"
This guy gives a good showing of the LTO. The biggest downside I think is you have to watch it like a TV vs look into it as a monocular.
Both are certainly better than nothing, you just need to understand real capability.
