Did you read the first post? He is using the drone to find the deer after it has been shot. So a recovery.What is he going to use it to hunt down his prey ? Seems to me if your going to use a drone to hunt, your no longer a hunter...........On the other hand, using it in keeping ones livestock/family safe is another issue
A guy actually made a business doing this that has expanded. Pay him just to show up and then pay him again if he finds your deer where he will then tell you where to find it. I don't hunt but found this deer recovery guy's youtube channel interesting.
