My position is that if we use electronic devices the same way that any outdoorsman/backpacker would use them, i.e. to locate geographical features, take photographs of nature, rescue in the event of emergency, etc., then I’m fine with it. Beyond that, using geographical mapping to make sure you're hunting in a legal area only makes sense, and takes nothing away from fair chase.
I don't use an electronic range finder for ranging game, although I do use one to range geographical features, rocks, bushes, etc, if I’m in a blind or tree stand. I don't have any occasion to use trail cameras, and am undecided about that, although there would certainly come a point where numerous trail cameras would violate fair chase. I think we would all agree that remote spotting by drones, or communicating game information by text or phone would violate fair chase.
