    I was hesitant to purchase this thermal monocular initially due to its cost. After two years of use hunting hogs at night, I really realized that I needed to detect my game and get ready. With my 4k night vision scope I couldn’t do it. That’s why I bought this one and I’m really happy with this purchase. This gadget also has a smart range finder which helps a lot on hunting. The video features are amazing. My family really likes this. They can see what I was doing on my last hunt.
