Another important thing to remember. You are looking at a miniature TV screen. You have no depth perception. It is extremely hard to judge distances. But expierance with your particular unit helps determine distance somewhat.
The very best hunting with thermal is the nights with no moon or before it has come up,or after it has set. You would be surprised how well animals can see your movement even with 1/4 moon.
And like a sunny day,during full moon that is high up,use the shadows to help hide you.
