Other than the obvious, like obeying both the letter and spirit of the law, my line is more along the lines of my own personal limits regarding gadgets and technology.
For example, if it uses batteries of any sort, I don't need or want it with me in the field (except for a flashlight).
If I have to carry it and it only has one use, then I will either leave it behind, or try to combine it with something else. The exceptions to this the weapon I'm carrying.
If whatever it is REPLACES a woodcraft skill rather than enhance it, then I try to avoid it. The exception here is matches or a lighter (although I've learned not to trust the lighters......in extremely cold weather they don't work well, and by being mechanical, then failure is not a question of IF, but WHEN), but I DO have the tools and skill to start a fire from scratch if need be, and even if you do have matches, you still have to know how to make and start a fire with natural fuels.
In this same vein are the use of calls. I will only use mouth or hand calls, because using them takes more personal skill than turning on a cassette. There are some species of animals that I call that use nothing but my hands, mouth and voice for.....owls, crows, and predators for example, and even a deer or two on occasion. Again, personal satisfaction.
I also use nothing but oilstones to sharpen all my knives with. It takes longer, but you get a MUCH finer edge, and I take a tremendous amount of pride in getting razor sharp edging on my cutting tools. This includes broadheads. For me, the personal connection of having the broadhead's edge that slays the deer come from MY hand makes the hunt all that more rewarding.
Again, these are my personal quirks, because for me it makes the "hunting" season last all year.
