no problem with detecting in Aruba or any other island in the Caribbean..........
newfie, you know what this means don't you? It simply means you didn't ask enough border consulates, lawyers, and bureaucrats there: "Can I?"
Using Mexico as an example, there was a humorous (but sad) story in the early 1980s, where someone had sent in a question to Fisher Co's periodical (because it had an monthly Q&A column) asking if it was legal to metal detect in Mexico. Apparently they were getting ready to vacation down there @ one of the tourist beaches, and they wanted to make sure it was ok to do. Fisher answered "
No, leave the detectors at home, blah blah".
In the following monthly edition of this periodical, several others wrote in to take exception to the editor's answer, asking this like "
Since when?" and
"who told you this?" and
"we go there all the time, and have no problems", etc.. Fisher, in defense of their earlier answer, clarified: When they had gotten the earlier inquiry, they asked! They merely picked up the phone, made a few phone calls to some legal travel consulate type people down there, and asked. I mean, who better to ask than Mexico themselves afterall?

Apparently someone couched their question in terms of raiding the pyramaids, exporting gold bars, shipwreck salvor federal things, or ......
WHO knows?? Anyhow, Fisher replied that they were simply passing on the answer they were given.
Oddly, detectors were then, and still are, a common site on Mexico's tourist beaches! And the major detector manufacturers (
including Fisher, doh!) have dealers in the bigger cities down there.
