Also mine doesn't reach far, i was told to put a stronger IR light on it and it would. but if you focus it for 50 yards it is bad blurry even ten yards either direction. like i said, i may not be using it right.
Another complaint i have with it and it may be this way with all of them as i know nothing about night vision, but after looking through it for a little i can't see nothing for a while. my eye just like being dilated.
