My family has property just up from Crandon, and I've been able to enjoy a total of maybe two solid weeks of detecting days around the beaches there. Have never hunted in the water at all but plan on doing so next trip. At Crandon, I spent most of my time in the more populated family and party areas working the water up to hide tide line.
NOTE ON FLORIDA BEACH HUNTING. Some of the ugliest coins in the world may be found in the dry sand there. hehheh
Managed a very nice 14k woman's ring with 5 small rubies. The wife calls that find her own now. Other less spectacular jewelry finds have been added to the total as well. The ring find is why I get to spend as much time detecting as I do on our trips.
Found a hammer from a flint lock, lots of modern trash, and plenty of identifiable change to more than keep me up in batteries. Park employees took my action in stride. Obviously I'm not the only detectorist they had seen. Hard to believe the high number near surface coin targets.
Have hunted all of the way from the southern tip of the Crandon beach North to the lighthouse. Not a problem working the wet sand by the half dozen or so high dollar condos next to the park either. Lots of modern coin lost near them.
