I am thinking about purchasing a FLIR thermal monocular. Mainly to be used for hog and coyote hunting. I have never had an opportunity to look through a thermal system. I do have one question. Would a squirrel show up in a tree, say under 50 yards? We do a lot of squirrel hunting with dogs and they like to get up in the tree and hide. Just curious if the thermal would make finding them easier.
Don't have a set myself (yet

) but 50 yards in the right conditions should show a squirrel like blob

I have seen rabbits on these small units at a good distance, via youtube vids - search them for a reference. & you came to the right place - Many thermal users on this site

It might be tough to see up in a tree due to the tree holding a lot of heat. If he's out on the smaller branches you shouldn't have a problem seeing one unless the squirrel is completely blocked by cover.
I have the PS32 model during day time you get more false readings(hot spots) I am sure do to the sun shining on stuff. Still alot of times in the evenings/early mornings I can see small critters in trees and at night I see raccoons and mice up in trees no problem 50 yards and well beyond on raccoons. Rain/fog seems to cut the clarity down some but it still works great.A few times the fog has blacked out my PVS-14 it was useless and the FLIR PS32 viewed right through it like it was a clear night thermal is cool stuff.

Those damn "hot" trees can indeed make things more challenging, particularly just after dusk.
Agree. On cool nights the PS32 is some cool stuff. I can see mice on the ground up to 50 yards easily. As already mentioned, trees do hold a lot of heat signatures but not a problem on cold nights.
Also, just so you know it is somewhat difficult to be extremely confident on what you are seeing at distances near 100 yards. For example a hog blob can look like a javelina or a small deer especially at distances beyond 150 yards.
