Taking a stand out in the field can be counterproductive. If detecting is legal but the groundskeeper says NO, what's the point in making an issue of it? You'll just get someone else against you when new policies are discussed and enacted. Even of you are completely in the right, and there is absolute permission granted to anyone who wants to hunt the place, what does taking the groundskeeper to task accomplish? Just the satisfaction of having his nose tweaked by his superiors? Congratulations, you've just made another enemy. Now, if they make a hard and fast rule against using a detector, that's when you want to fight them legally/politically.I've never been arrested for metal detecting or trespassing, I've actually never been hassled by anybody while metal detecting. Why? Because I don't go where I don't belong!
Sometimes we must take a position and make a stand, even if it's an inconvenience. I'm not a victim, and I won't be intimidated by any individual, including a police officer. When they start making the laws up as they go along, it's time to defend ones civil rights.
I was pretty wild when I was younger, I spent a lot of time in court and a few nights in jail, I have calmed down since then.
