There's a big difference between NV and Thermal, and their applications. We had all the best gen 3 NV, and some pretty good FLIR thermal stuff. After playing with both we have decided to upgrade the thermal, and ditch the NV. The main reason was already mentioned in a prior post.....even with gen 3 NV it's difficult to determine whether your shooting at a fox or small coyote at a few hundred yards.
I would not want to be in the position to explain to the rancher or farmer why his dog is no longer on all fours....
We just upgraded from the FLIR PS 32 thermal to the Pulsar HD 38. Quite a significant amount of money at $5k a piece, but there's no comparison between the two. With the Pulsar, we pull heat signatures at close to 1000 yds, and can positively identify predators at realistic shooting distances in the dark. By realistic, I mean a few hundred yards.
I'll find some good pics we took utilizing the iPhone and post them up..
