I've heard a lot about thermal imaging sights and want to buy them, are there any new models that are worth my attention?

Those who seek will always find, so yes, I have an option for you. I liked the thermal scope https://www.atneu.com/thermal-scope-mars-hd. Previously, I didn’t even know where I could buy it until I noticed one from a friend. It turns out they are very popular and reliable. I've used it once already and loved it!
