I live in cape coral and detect a lot at the yacht club beach. find mostly trash, nails, screws, bolts, but i have found jewelry and a watch left behind by sunbathers. I mostly detect on Sanibel, FMB or the Sanibel Causeway.
not sure about cape coral but naples is a tourist town an i find ALL their clad! I always find stuff one or 2 beaches down from the most populat one. HH
