Then there is the reality of practicability and probabilities.
When you "see" deer in a field with your binoculars, you are normally much closer to having an opportunity to immediately stalk that deer than when one is typically seen on a cell cam pic.
More often, bucks are only "feeding" in a "stalkable" spot for a matter of seconds to a couple of minutes. Perhaps different story if you hunt over corn piles (which opens up another can of worms on ethics).
I run several cell cams year round.
Rarely are they set to "instantly" send pics, simply because they run batteries down so fast that the benefit of a cell cam becomes countered by more frequent visits to replace batteries.
Even when set to "instantly" send, there is still a delay (typically 1 to 3 minutes) before it comes in, and then, the person getting it simply may not be able to view until at least minutes or hours later.
And then, MOST often, the person receiving the pic, even if out hunting during hunting season, is in no position to suddenly go pursue the deer (or turkey) for which a pic just came in (often hours after it was taken).
Sure, there are exceptions to every generality.
But for the most part with most users, cell cams are just another scouting tool.
When it comes to "ethical" perspectives of some, it could be argued a rifle scope is less ethical than any trail cam? Maybe a turkey call? A "real hunter" should use only his own mouth?
One could argue it's just "not fair" that a retired person is free to "scout" (boots on the ground) 7 days a week, while other people have to work? Maybe the state should limit everyone to only being able to hunt 1 day a year, just to be fair to everyone?
Just saying, maybe we should be more concerned about stoking division between hunters than worrying about things that typically are not the problem we fear?
Back to one of my primary thoughts:
I'd rather have lots of hunters doing more of their "scouting" via using trail cams & cell cams
than via their physically more frequently putting their boots on the ground. This is my thought whether private or public lands, again, generally speaking. The less the areas are "disturbed", the better the hunting for everyone, including those who prefer not to use trail cams.
