Metal detecting in a foreign country?

[DetectorGuy]

Hi folks, I am going to Puerto Morelos Mexico in 7 days and I'm stoked. I have all my dive gear packed, weighed, and inventoried. I have never been on a vacation since Ive been certified. No mater where I went on vacation before it always had to do with water (if you call a glacier just frozen water). This will be great even if I only get a few dives in. Another family is going with us so there will be two of us that dive and six snorkelers. Two rental cars so the divers can get to the dive shops and the others can shop, sightsee, or ??? (with less guilt). I packed my main regs and my pony reg. I packed my two detectors and fresh batteries. I went out and bought a 3mm shorty and 3mm short boots anticipating warm water. The weather is forcast to be 82 degrees during the day and 69 degrees at night. We are going to be there for 8 days if everything goes good, and if it goes bad... 5 to 10 with good behavior. I try to do what I can to not promote the "Ugly American" image when I travel most of the time. This time it is a little different and I will need to be a bit more stealthy with the detectors in tow. I really wish I had one of those little wrist detectors that look like a wrist computer on steroids. They were about the same price as the Garrett Sea Hunter 2 but the reviews I read said that they were not as good. I am not going there to take artifacts or antiquities but even a 2 year old Peso would be cool.
