Florida Metal Detecting Laws — Research Overview

An orientation to metal detecting and treasure hunting rules in Florida, covering federal land, state land, private property, and who to verify with. This page is general research information, not legal advice. The state-level summaries below are our own category-level orientation and are not sourced to a Florida statute, code section, or agency ruling. Rules change and differ by unit — verify with Florida State Parks before detecting.

Public and federal land in Florida [UNSOURCED SUMMARY — confirm with the managing federal unit]: Most beaches allow detecting; state archaeological zones are off-limits. Federal land is also governed nationally by the Archaeological Resources Protection Act (ARPA) and the Antiquities Act, which prohibit disturbing archaeological resources over 100 years old without a permit.

State land in Florida [UNSOURCED SUMMARY — confirm with Florida State Parks]: Florida state parks require permits; most prohibit detecting outside marked beach areas.

Permits, permissions, and best practices in Florida [UNSOURCED SUMMARY]: Offshore salvage requires admiralty contracts. Onshore: stay below mean high tide on public beaches. Always carry written landowner consent for private ground and photograph the permission document.

Terrain and productive regions in Florida: Beach, dune, mangrove, and shallow reef. Storm-cycle beach detecting is highly productive. Top areas to research include Treasure Coast (Sebastian–Fort Pierce), Florida Keys, St. Augustine.

Documented cases relevant to legal research in Florida: 1715 Spanish Plate Fleet wrecks; Atocha-era cargo (Keys); Gasparilla pirate caches — legal status of any recovered items depends on land ownership at the moment of discovery.

Federal rules that apply in Florida regardless of state law: ARPA (16 U.S.C. 470aa-470mm) protects archaeological resources 100 years or older on federal and Native American land; NAGPRA (25 U.S.C. ch. 32) governs Native American remains and cultural items; and the National Park Service prohibits metal detector use in park areas under 36 C.F.R. 2.1. Treasure trove and lost-property doctrine are set by state law and are not summarized here.

Verify with the governing agency in Florida: Florida State Parks (https://www.floridastateparks.org/). Archaeological designations and permitting: the Florida State Historic Preservation Office, listed in the NCSHPO directory at https://ncshpo.org/. Federal land: Bureau of Land Management, National Park Service, and USDA Forest Service.
