Casca brings up something interesting, when he says:
"Theres some places here a lot of people go, but it not legal to do so. Its not really enforced."
Now, at first blush, a multitude of people here would look at this, and immediately hop on the part about "enforced", and correctly say "that doesn't matter". Right? Whether or not anyone actually cared, or whether there's anyone there to care or enforce, would technically "not matter", right?
But here's a question: why is it then, that when we see on this forum where someone is about ready to travel to another location (a different city, or a different beach, etc...). And they inquire on a thread "is it ok to detect there?", why is it that a common answer will often-time be the following answer:
"Ask around to the persons who are there. Like if there's a club, a dealer, etc...., that they'll know the skinnny on their own area".
THAT TOO at first glance appears to be a valid answer, right? I mean, who better to know where to hunt, than the person who's hunted some place for decades? But notice that even though local hunters in a certain place just routinely detect a certain beach, or certain parks, never made it "right". Ie.: there *still* might be a law against it (given enough morphing and effort to apply various "alterations" or "cultural heritage" verbage, you can always find yourself a "no", if you ask enough questions.
Why is it then, that we all subconsciously agree to ask local hunters? Because obviously, if they've never had a problem, then one assumes that it's ok. In other words, you and I (even the most skittish) DO tend to give a lot of credence to "actual results", do we not? However, as you can see, this only means .... a lot of times .... that no one's ever gone and asked enough questions. You're never 100% gauranteed that a busy-body won't come up and gripe that you're bothering earthworms or whatever.
So my question to the OP is: What type of site are we talking about, that those fellows wandered over into? Private land? Some form of govt. land? And if so, what type? etc...... There's a million shades of grey here.
