The other night I took my big thermal imager on a foxing session to test it out with a new mini-DVR that I bought recently. After a while, I spotted a fox, and zoomed in on it, some 250 yards out. I then locked the thermal in position on the tripod and left it running while I set off with the rifle. At some 200 yards out, I set my .22-250 on the sticks and fired when I was happy that the shot was a good one. Here's a clip of the results: http://youtu.be/UszcvQpe52A
