Hi Mike; I have hunted in St Maartin...at orient beach...not the best for detecting. Usually big waves and rough. maybe on a different side of the island. I think some of ST thomas is off limits. Talk to Les. I know he has hunted st Maartin too.
Some action near Orient beach but you will take a pounding from the waves. I felt like a piece of meat that came off the butcher tenderizing block. May not be like that all the time but in the 6 times I've been there it WAS ROUGH.
Good luck on St. Martn. Not to be downer but I agree with the others about Orient Beach on the French side. Came out of Orient Beach with disabled Excalibur 1000 after only an hour so. Another part of the island also took out my Fisher CZ21 too. Needless to say a very disappointing visit for me. My trip was in late April of this year. It would be great for you report back to us with better success. Have thoughts about a couple other places on the island on the dutch side if you want to pm me.
