Where to Hunt
According to the operations procedures manual of the Florida Park Service, metal detecting is only allowed in coastal parks between the waterline and the "toe of the dune," which is determined by the park manager. You should check with a park ranger prior to detecting as this area varies from park to park. The use of metal detectors in all other areas of Florida state parks is prohibited.
Collecting
Natural items and items of historical or cultural value are not allowed to be removed from the park. Also, individuals who find items such as rings or keys are encouraged to turn them in to lost and found. You should always check with the park manager prior to hunting to be sure you understand what you are allowed to keep from your search.
Designated Archaeological Sites
Designated archaeological sites are located throughout the park system. A permit is required to use a metal detector in these areas, and any historical artifacts you find will become the property of the state.
Recovering Lost Items
If you lose an item on park property, you are allowed to use metal detectors to retrieve it; however, you must be able to specifically identify the item. The park manager will arrange for a time to search, and anything found in addition to your item must be turned over to the park.
