In rare circumstances, I might be more OK with it. The example that comes to mind is
@Khunter moose hunt where he wounded the bull and busted his ass trying to find it. Whether he would've used it is up to him, but I wouldn't feel as bad about a situation like that.....once-in-a-lifetime tag and trying to recover an animal most people will never even get the opportunity to hunt. Some regulations would probably still need to be developed..maybe no hunting X number of days after use? Not sure what, but it would require more thought if allowed.
For finding lost dogs, etc....all for it. Could also be a great aid in finding lost people from what I've seen in the videos for finding animals.
