If a animal appears in your thermal and is blurry you can refocus scope or change a few settings and do a NUC. if it's then still a blur then it's still out of your I.D range and you shouldn't be shooting anyway. Also why you want a thermal with 384 or better resolution as it allows you to positively I.D. farther out. I have three different thermal brands and can positively I.D out past 300 yards to a 1/2 mile, from a mouse to a deer or cow but if humidity is high then the I.D. range goes down.
