This discussion and my my own thoughts over the last year on this subject have led me to the conclusion that the line should be drawn at electronics, period. Electronics more than any other technology take the human element out of hunting. I know we will never get rid of GPS or OnX, or two-way radios as they are all considered safety devices. And Rangefinders are heavily entrenched. It was range finders that made the long range hunting craze possible. Without them a 400 yards shot would still be considered long range. We will probably never eliminate range finders, although, I would happily give up my range finder before losing annual OTC opportunity.
I know that rifles, optics, clothing, are all technologies that increase our hunting success. But, I think those technologies can only advance so far. There does not seem to be a limit to where electronic technologies can go.
At least with range finders, lighted reticles and other earlier tech, the hunter still had to use their own eyes to find game. Thermals will eliminate that, if you don't believe current tech is effective, you might at least acknowledge that it will eventually get there. But put in the camp that believes the tech already exists and is being used far more that I knew just a couple years ago.
Why are we trying to make hunting easier? Even cellular trail cameras are too far in my mind. So what if you have to drive 2 hours, and hike 3 miles to check your camera. Such effort is what separates those who are dedicated from those who are not. If you eliminate electronics entirely, the amount of effort required to scout goes up even further. Is that a bad thing? Some years I am able to make time for a lot of scouting, other years not so much, that's life. Just because a technology exists that would make something easier doesn't mean it is good in every context.
