Florida is one of the best states in the country to swing a detector: hundreds of miles of public beach, a steady supply of modern drops, and storms that move sand every season. It is also one of the easiest places to get the rules wrong, because there is no single Florida rule. The beach in front of you might belong to a city, a county, the state or the federal government, and each one sets its own terms.
This guide explains how the rules break down so you know who to ask before you dig. Rules change, and local ordinances vary, so treat this as a starting point rather than legal advice and always confirm with whoever manages the land.
Most of the legal ground here is beach, which is where beach metal detectors earn their keep. For the rules on federal land and in other states, see metal detecting laws in the US, and if you also hunt further west, read metal detecting in Texas.
Most coastal cities and counties in Florida allow detecting on their beaches. This is where the majority of Florida detectorists spend their time, and it is the most forgiving place to start.
The details are set locally, and they genuinely differ. Some places need no permit at all. Others ask you to buy a pass, keep out of dunes and preserves, or fill and compact every hole. A few have rules about historical objects found on county land. Inland, some counties sell an annual detecting pass for named parks, and at least one city requires items of value recovered on its property to be turned in to the police.
Before your first hunt on a new beach, check the city or county code, or simply call the parks and recreation department. It takes five minutes and it answers every question in this section for that exact spot.
The Florida Park Service is clear on this: detecting is prohibited in state parks, except at coastal parks. Even there, it is limited to beach areas between the toe of the dune and the high-water line that the park manager designates, and it is not permitted in submerged areas.
In practice, that means:
Note that if a city or county leases coastal land from the state, state rules still apply on that land.
Federal land is off-limits. National parks, national seashores and national monuments in Florida do not allow metal detecting, and military installations set their own restrictive rules. If a beach is part of a national seashore, leave the detector in the car.
Everything below the mean high-water line is state sovereignty submerged land. Owning or carrying a detector in the water is not illegal, but disturbing the bottom sediment is. That rule surprises a lot of new beach hunters, so read it twice before you wade in with a scoop.
River bottoms count too. Divers sometimes assume artifacts in Florida rivers are fair game. They are not: the state's isolated-finds policy, which once let people keep certain river finds, has been discontinued.
Under Florida law, artifacts recovered from state-owned or state-controlled land, including submerged land, belong to the state. Digging for artifacts on state land without a permit from the Division of Historical Resources is a third-degree felony. Fines can also be imposed on anyone who salvages treasure, wrecks or other historic objects on state land without written permission.
The Spanish treasure coast is famous for a reason, but the wrecks themselves are worked under state permits. A beach hunter finding a modern ring is in a completely different legal position from someone pulling colonial coins out of the surf zone.
Get the landowner's permission, in writing if you can. Detecting on private land without it is trespassing, and finds made while trespassing aren't yours to keep.
