Would be nice to have a P&Y member or two chime in and provide their/the organization's interpretation. I know one method the electronic devices clause speaks to, and that's using a cell phone, walkie talkie or other communications device, to direct another hunter to a game animal, for example, during a stalk. Or calling your buddy and indicating you just jumped a nice buck and he's traveling fence line X. " If you hurry to spot Y, you can get there before the buck does."
I didn't have a problem with trail cameras when they first came out. Putting one out on the back 40 to see what's there as well as get pix of other critters seemed rather harmless. However, nowadays folks set out 20, 30, 40 trail cameras in a relatively small area. (I read a piece on Stickbow (think it was titled trail camera primer) a while back where a guy had more than 40 cameras on a 300 acre piece of land.) When you put that many cameras out, you're taking unfair advantage because it then becomes quite easy to pattern one or more animals. Pretty easy to determine exactly when, where, and how an animal(s) moves. Not too difficult to then set up to waylay the animal in its travels.
Personally, anymore, I don't consider use of a trail camera in any capacity as fair chase.
