    I bought this OTS 4T thermal monocular for coyotes hunting. And I was surprised. The picture was perfect. I could spot coyotes out past 100 yds. I even saw a bird 30 yds away in a tree the other night. The battery lasts around 10 to 12 hrs. This thing is incredible. I’m going to sneak on to somebody stealing my gas 🙂
