In the city of Riviera Beach Florida, on Singer Island, Palm Beach County, I recently read a sign that stated that NO METAL DECTORS were permitted on the beach. This is a Public Beach in the Town of Riviera Beach. I do not know if this applies to all beaches in Singer Island or just the one public beach. I was not in the mood to tempt fate and decided against detecting the beach.
I have a picture of the sign. Hope you can read it.
Have no idea how these restrictions can apply to a 'public' beach. By the way, I was there for two days and did not see anyone on that beach. Guess there must be way too many restrictions.....
