The Thor 320 3x Thermal scope is my second night vision scope. I also have a ATN Aries Mark 7700
generation 3 night scope which I bought about 8 years ago.
The Thor 320 3x has 3 magnification settings - 1x, 2x and 4x. I don't know if the 4x versus the

scale picture in comparison.

my corn field and as it came out I noted that a single leaf was all that it took to blockout the
thermal image. I took the scope out in the car and discovered that the window had to be down for the
scope to work and also that it would not show if a car is occupi...
