Laws are weird here in Indiana. You can use a drone with thermal to recover a dead deer. You cannot use the same equipment to recover a wounded deer.
That is an interesting legal Catch-22. In Indiana, is that called the Schrodinger's Deer Statute?
If I can feel the deer's pulse, or lack thereof, I probably don't need a drone to locate the body.
On a serious note, has anyone used a hand-held (or drone mounted) thermal imager to locate a lost deer? How expensive of a unit do you need to purchase for that application? Can you spot warm blood droplets with a sensitive enough unit?
P.S. I have helped buddies look for lost deer twice and found neither. One clearly had frothy lung blood in the blood trail. It suck to lose a deer!
