Here are some of the highlights from the 2012 pig hunting season. This year we had a thermal weapon sight as well as the thermal camera on the UAV. The thermal weapon sight made a huge difference in the ability to detect the hogs from long distances and was a joy to shoot with as well. The majority of the pigs taken where with a .308 equipped with an ATN ThOR 640 2.5X scope.
The UAV is a Skywalker 168cm with RangeVideo OSD and a FLIR TAU 320 camera. I use 2.4Ghz with circular polarized antenna for video.
I think the thermal cams are about $5000 ? if I am not mistaken
the UAV are quite a range depending on things ? $1000-$8000 without cameras depending on options
I know my next big project is to get into the UAV photography thing
