I have a strong opinion on this topic, but just my opinion. If they are allowed on that particular public land, then they are a legal means of scouting and should be left alone...period. If you tamper with those cameras; i.e, pull the chips, put something over the lenses, or worse yet steal it, then you are no better than any poacher or baiter out there...IMO. Now that being said, I only have two cell cameras, both of which I use to monitor for trespassers on our own property; however, I own 18 other non-cell cameras I use throughout the season in various locations...one public property is included. Fortunately, I've never had anyone monkey with the three I use on that public property, but I do hunt about 2.5 miles off the main road so that helps. But, I'll echo what some had said on here. Having a trail camera out doesn't necessarily increase one's odds. For one, I've found many hunters don't know how to scout out the best places to hang a camera, and two, there are a lot of inferior cameras out there that miss A LOT of action, so there's that. I consider myself one of the best for scouting using cameras, and even I can tell you in most cases, at best you'll just going to get an inventory of what's in the area when hunting public property. That's good enough for me since I'm trophy hunting. The last two years are a perfect example of why trail cameras are ONLY a method of scouting. On this public land in the 2021 season, I had 3 shooters on my hit list from camera scouting. There was one day I had planned to hunt and something came up and one of the shooters graced my camera at 9 am 40 yds from my stand, other than that I never encountered one of those three shooters and ended up killing a 5.5yr old 9pt that I had NEVER seen on camera!...though he did walk in front of my camera and kick out my mock scrape seconds before I shot him. This year I only had two shooters on camera and one was a 140" 10pt! He got shot by a guy .80 miles from where I was getting pictures of him, and it was this guy's first time hunting that public land. I talked to him for a while, great guy and I'm happy for him, but he literally just blindly went into the woods that morning and climbed a random tree in the dark and killed that buck at 8:30 am just as he was about to get down and move to another spot!...and almost a mile from where I was hunting the same buck. So, two years in a row and I've yet to encounter one of the shooter bucks I got on camera...and I'm pretty dang good at camera scouting. What it mainly does for me is let me know what high-end bucks may be in my area, so if a 120" buck walks by I have the knowledge to know if I let him walk there's a chance of something bigger. That's about the extent of my benefit of using cameras on public property. If they're legal to use, just leave them alone and know you have just as much chance as the guy who put out that camera!...IMO.
