I like the looks of the Thor4, 1800-3000$
I have the THOR-HD 640x480 2.5-25 and it works well. But I have a 6x Gen4 night vision scope that you can see individual bean pods on soybeans at 100 yards. No question about your target then. I use a pair of Gen 3+ night vision goggles for scanning and they can be worn on headgear. You can add magnifiers that screw on the front too, I use a 3x. With either thermal or night vision you need to be up on the scope so I like the AR platform with an adjustable stock so you can shorten it way up. I tried my thermal on a savage rifle that has spacers in the stock and was able to get it short enough but it seems more awkward when I put a suppressor on it.
Had a friend that had a wicked hunting light and he bought an infrared bulb for it and uses it with the ATN X-Sight 4K Pro 5-20x Smart HD Day & Night and it works well. But the night vision is worhtless without the strong infrared but that scope was 700 something.
