Honestly I don’t know what Id ever use them for. A guy set up a corn field/deer hunting spot on a spot behind my partners property with motion cameras and such. He had a drone that either he rigged up or bought with an IR camera on it. Dude would fly over the area and check how many deer and where they were before going hunting I guess. It’s not even “fair.”. You can spot the deer easily and they have no idea you were ever there. I remember seeing several photos/videos where he was tracking them. At a certain point you have to feel like it’s just overkill. Although if he was using as much of the meat as he could I guess it’s still better than what we do to cows and such
