Is Metal Detecting Legal? Federal, State & Private Land Rules (2026)

Quick Answer: Metal detecting is legal across most of the United States, but the rules change completely depending on who owns the ground. It’s banned outright in national parks and monuments under federal regulation 36 CFR 2.1(a)(7), generally allowed in national forest recreation areas, permit-by-park in state parks (rules set individually, not statewide), usually fine in city and county parks away from historic sites, and always fine on your own land or private land you have explicit permission to search. There’s no single national law — the safest move before any new hunt is a two-minute check with whoever manages that specific patch of ground.

Last updated August 28, 2026: Re-verified against the current eCFR text — 36 CFR 2.1(a)(7)‘s blanket ban on possessing or using a metal detector in any National Park Service unit remains unchanged, with the same narrow exceptions for authorized scientific/administrative use and boat/aircraft navigation electronics. Added our new state-specific guide for Florida below.

New detectorists ask this question before they ever swing a coil, and for good reason: get it wrong on federal land and you’re not looking at a warning, you’re looking at a federal offense. Get it right and the hobby is wide open — most of the country’s parks, beaches, and yards are fair game. This guide breaks the legal picture down by who actually owns the land, because that’s the only variable that matters.

The one rule that actually decides it: who owns the land

There’s no single federal “metal detecting law.” Instead, four separate landowners set four separate rulebooks, and none of them defer to the others:

National parks: banned outright, and it’s a real federal regulation

This is the one absolute in an otherwise patchwork picture. 36 CFR 2.1(a)(7) — a real, citable federal regulation — prohibits possessing or using “a mineral or metal detector, magnetometer, side scan sonar, other metal detecting device, or subbottom profiler” anywhere inside a National Park Service unit. That covers every national park, national monument, and NPS-managed historic site in the country, not just the famous ones. The regulation carves out exactly three narrow exceptions: a detector broken down and packed away so it can’t be used, electronics used purely for boat or aircraft navigation, and detectors used under an authorized scientific, mining, or administrative permit. Recreational detecting doesn’t fit any of the three. This is why you’ll see detectorists insist “never in a national park” without qualification — the regulation genuinely doesn’t leave room for a judgment call.

Stack the Archaeological Resources Protection Act (ARPA) of 1979 on top of that, and the stakes get higher on any federal land, not just parks: digging up an artifact more than 100 years old without a permit is a criminal act under ARPA, and enforcement treats it that way — confiscated gear and prosecution, not a polite citation.

National forests: usually fine in recreation areas, off-limits at archaeological sites

National forests are managed by the US Forest Service, a different federal agency with a different mandate — recreation and multiple use, rather than the NPS’s strict preservation mission. That difference shows up directly in the rules: recreational detecting is generally permitted in designated recreation sites and picnic areas, and mineral prospecting is allowed in approved zones (often with its own permit for actual prospecting, separate from casual coin-and-relic hunting). What’s still off the table everywhere in a national forest is any known archaeological or historical site — the same ARPA and National Historic Preservation Act protections that apply on NPS land apply here too. If you turn up something that looks archaeological, the same rule applies as anywhere on federal land: stop digging and report it to the local ranger district rather than removing it.

State parks: permit-by-park, and there’s no single answer

This is the messiest tier, and it’s the one most detectorists get wrong by assuming a state-level rule exists. It doesn’t. Individual state parks — sometimes individual units within the same state system — set their own conditions, and a permit from one park almost never covers another. The conditions that show up most consistently across states:

• A site-specific permit, often free, sometimes a small fee, applied for before you go
• Daylight-only hours — sunrise to sunset, no exceptions
• Hand tools only — a screwdriver or small trowel is fine; shovels and spades are commonly banned
• Restoration required — any disturbed ground must be put back to its original appearance
• Archaeological sites, historic structures, and anything on the National Register of Historic Places are universally protected, permit or not

Practically: call or check the specific park’s website before you go, every time, even if you’ve detected there before under an older permit. For a worked example of exactly how one state’s rules break down — designated-area-only detecting rather than a park-wide permit — see our metal detecting in Michigan guide. Ohio takes the opposite approach with one clear-cut rule instead: sand beaches and mowed areas open by default, everything else permission-only — see our metal detecting in Ohio guide for how that plays out. North Carolina flips the usual pattern: its state parks are nearly closed to detecting, while municipally managed public beaches carry no such restriction — see our metal detecting in North Carolina guide for that state-park-versus-beach distinction. Texas layers on a rule none of those three have: even on legally open ground, the Texas Antiquities Code makes anything over 50 years old found on public land a state archaeological landmark you can’t keep — see our metal detecting in Texas guide for how that changes the calculus. Florida raises the stakes further still — removing anything roughly 50 years or older from state land is a third-degree felony under Chapter 267, not just a confiscation risk — see our metal detecting in Florida guide for the toe-of-dune park rule and Treasure Coast salvage-lease no-go zones. Arizona flips the pattern one more time: its state parks ban detecting with zero exceptions, but BLM land and six national forests treat it as routine casual use requiring no permit at all — see our metal detecting in Arizona guide for why the state’s best gold ground sits almost entirely on federal rather than state land. Colorado adds a wrinkle none of those states have: state parks allow searching but ban digging or removal outright, and its most famous gold district is checkerboarded with still-active mining claims you have to check before you dig — see our metal detecting in Colorado guide for how to tell claimed ground from open public land. Georgia goes further than any state in this series: O.C.G.A. § 12-3-10(n) bans even possessing a metal detector in a state park, historic site, or recreational area — not just digging in one — see our metal detecting in Georgia guide for where that leaves the Dahlonega gold belt and specific beaches like Tybee Island. New York breaks the pattern in a different way than any state so far: it isn’t one agency’s rule but two, run independently of each other — a paid $40/year state permit for mapped Long Island beach zones, and a separate free city permit for open fields in the five boroughs — see our metal detecting in New York guide for how the two systems split. Virginia’s entire state park system narrows down to just six man-made lake beaches, each needing its own individual DCR permit — see our metal detecting in Virginia guide for why the Virginia Antiquities Act turns digging a battlefield into a criminal charge, not just a confiscation. South Carolina splits the license and the activity apart in a way none of the others do: its Underwater Antiquities Act does issue a hobby license for collecting artifacts from rivers and coastal waters, but that license explicitly excludes metal detecting and mechanized equipment — see our metal detecting in South Carolina guide for why a state permit process can exist and still not cover the hobby it sounds like it should. Tennessee’s state parks have no general recreational permit path at all — only a supervised lost-item exception — and a huge share of the state’s lake shoreline sits under a separate TVA ban on top of that. See our metal detecting in Tennessee guide for why rivers and non-TVA lakes end up being the most reliable public ground in the state. Kentucky goes a step further than Tennessee and is the most restrictive state in this series so far: its state parks carve out no recreational exception at all, not even a supervised lost-item search — only park staff, law enforcement, and utility crews may run a detector — and a separate federal ban closes Land Between the Lakes’ Kentucky Lake and Ohio River shoreline on top of that. See our metal detecting in Kentucky guide for why Louisville bans detecting citywide while Bowling Green allows it in daylight. Oklahoma is the first state in this series where the hobbyist reference sites and the state’s own official page flatly disagree — several detecting-law blogs describe a park-manager permit for Oklahoma state parks, but the parks system’s current official FAQ states plainly that metal detecting and magnet fishing are prohibited at all state parks, with no permit listed. See our metal detecting in Oklahoma guide for why the real public-land options are a Corps of Engineers lake permit at Eufaula or Texoma, or Tulsa’s city parks. Missouri flips the pattern entirely — it’s the most open state park system in this series so far, with 11 named parks allowing detecting on designated beaches through a free annual registration and no permit lottery. See our metal detecting in Missouri guide for the full park list, tool-size limits, and why Columbia and St. Louis County each run their own separate rules on top of the state system. Indiana repeats the aggregator-vs- official-source conflict seen in Oklahoma, but in reverse: several detecting-law directory sites list Indiana Dunes State Park as strictly prohibited, while the park’s own visitor FAQ confirms beach detecting is allowed September through May with written permission. See our metal detecting in Indiana guide for that conflict, the state/national park naming trap next door, and why Indianapolis has no published policy at all. Wisconsin splits along state/county lines instead: DNR land only permits detecting to recover one named lost item, by written permit, inside a May 1–October 15 window, while Dane County Parks runs a genuinely broader annual hobby permit on its own land — the opposite of most states in this series, where counties either mirror the state or stay silent. See our metal detecting in Wisconsin guide for the county permit built with a local detecting club, and why the state’s 50-year archaeological cutoff is stricter than the federal baseline. Alabama adds a two-layer catch none of the others quite match: Park Manager permission to detect in a state park doesn’t override a separate rule banning removal of anything you find, while Gulf Coast city beaches stay open without a permit right up until you cross into Gulf State Park’s own boundary on that same stretch of coast. See our metal detecting in Alabama guide for the felony-adjacent misdemeanor charge that protects the state’s aboriginal mounds and burial sites. Illinois introduces a restriction none of the other 18 states have: Cook County’s Forest Preserve District bans even possessing a metal detector on its land, not just using one, with fines reported between $75 and $500 per violation. See our metal detecting in Illinois guide for the IDNR state park permit system and the felony-track excavation law layered on top of it. Washington draws its beach line narrower than any state so far: detecting is allowed only between the water’s edge and the mean high tide line on the outer coast, explicitly excluding Puget Sound, and its archaeological resources law reaches private land as well as public. See our metal detecting in Washington guide for the free state park registration system and that private-land wrinkle. Oregon gates access even tighter: rather than a park-wide permit or registration, the state limits detecting to a published list of named locations covering both its state parks and its Ocean Shore State Recreation Area, on top of a $250 found-item turn-in rule not written this explicitly anywhere else in this series. See our metal detecting in Oregon guide for the full approved-locations system. Utah skips a dollar threshold entirely: every find of value goes to a state park’s lost and found regardless of worth, but with a twist none of the other 21 states offer — if nobody claims it within 60 days, the detectorist who found it can claim it back. See our metal detecting in Utah guide for that 60-day rule and the antiquities statute that ties its felony threshold to a $500 valuation. Minnesota is the strictest of the 23 states covered so far for state-park access: Rule 6100.0900 allows detectors in state parks only to retrieve a specifically identified lost item, with no general recreational permit path at all, leaving narrow county programs like Dakota County’s two-beach permit as the closest thing to a workaround. See our metal detecting in Minnesota guide for that county-permit system and the two-tier penalty that separates ordinary unlicensed digging from disturbing a burial ground. New Jersey is the first state in this series to split its permit system across three separate agencies rather than one: a state-park permit, a different New Jersey Water Supply Authority permit for reservoir land like Round Valley and Spruce Run, and an unsettled Wildlife Management Area question, on top of every Jersey Shore town’s own beach ordinance. See our metal detecting in New Jersey guide for how those systems differ and why a beach badge isn’t a detecting permit. Maine, the 25th state in this series, runs one of the more approachable state-park systems covered so far: a single Rule 4 grants detecting outside historic sites with a written permit obtained directly from the specific park, rather than a statewide application. See our metal detecting in Maine guide for why Footbridge Beach draws detectorists that Popham Beach State Park doesn’t, and the professional-only archaeology permit that applies statewide. Massachusetts, the 26th state in this series, flips the usual pattern: 302 CMR 12.04(12) exempts coastal and inland sandy DCR beaches from any permission requirement at all, while every other DCR property needs a park supervisor’s permission limited to recovering lost personal property. See our metal detecting in Massachusetts guide for how that beach exception works alongside the statewide Antiquities Act. Maryland, the 27th state in this series, is the first where one short stretch of coastline runs three separate rulebooks at once: the federal Assateague Island National Seashore bans detectors outright, the adjacent Maryland-run Assateague State Park allows them only in an off-season window on the ocean side of the dune, and the nearby town of Ocean City requires its own paid municipal permit in yet a third, different season. See our metal detecting in Maryland guide for how those three jurisdictions stack up, plus the statewide beach exception that excludes Point Lookout and Calvert Cliffs by name. New Hampshire, the 28th state in this series, is the first where the permitted locations are spelled out directly in the statute itself: RSA 227-C:12 names beaches, athletic fields, school grounds, cemetery perimeters, and picnic areas as open with no permit required. See our metal detecting in New Hampshire guide for the 2024 bill that tried to strip two of those categories after a safety incident, and why it failed. Vermont, the 29th state in this series, restricts detecting by the age of the landscape itself: state land is open only on ground already disturbed by park development, a mandatory staff check-in is required first, and stone walls and cellar holes are named off-limits by rule — features that blanket the hillsides left behind by Vermont’s abandoned 19th-century hill farms. See our metal detecting in Vermont guide for the 3-inch dig cap and why hand gold panning stays legal under the same hand-tools standard. Connecticut, the 30th state in this series, is the first to require handing over an entirely modern category of finds: DEEP’s surface-collection rule lets detectorists keep most of what they dig, but jewelry and watches must be turned in to the park manager rather than pocketed. See our metal detecting in Connecticut guide for the beach-sand digging exception and the class D felony penalty for unpermitted archaeological-preserve digging. Arkansas, the 31st state in this series, is the first where the state’s one true detecting exception doesn’t actually help: Crater of Diamonds State Park is exempt from the general state-park detecting ban, but its own equipment rule bans detectors on the search field, and diamonds aren’t metallic in the first place. See our metal detecting in Arkansas guide for the nine-beach season window, the 6-inch hole cap, and why Corps of Engineers lakes need a second permit on top of the state park rules. Iowa, the 32nd state in this series, runs on the newest rule chapter of any state so far — effective June 2025 — and flips the calendar most detectorists expect: the summer swim season’s legal window is shorter than the off-season’s. See our metal detecting in Iowa guide for the exact hours, the drained-lake exception, and why Effigy Mounds National Monument stays off-limits. West Virginia, the 33rd state in this series, splits detecting and keeping into two separate questions: state parks don’t ban carrying a detector, but removing anything you find requires written authorization from the Chief of Parks and Recreation that most hobbyists never obtain. See our metal detecting in West Virginia guide for the archaeological-permit layer and why New River Gorge National Park stays closed. Pennsylvania, the 34th state in this series, publishes the most detailed official state-park rulebook covered so far — fixed hours, a defined beach season, screwdriver-only tools — but every one of those terms is conditional on prior approval from the specific park manager, a step the rules page itself doesn’t headline. See our metal detecting in Pennsylvania guide for the State Game Lands removal split and the History Code’s misdemeanor penalty for unpermitted excavation. California, the 35th state in this series, has no single statewide answer at all — detecting is decided park by park, and three units in the state’s own historic Gold Rush region have banned detectors within the last three years, starting with the actual 1848 discovery site. See our metal detecting in California guide for the $10,000 archaeological-disturbance fine ceiling, the highest documented anywhere in this series. Hawaii, the 36th state in this series, has the shortest rule of any state covered so far — sand beaches only — but backs it with the harshest penalty: HRS Chapter 6E’s unmarked-burial-site protections carry a fine of up to $20,000 per violation, double California’s previous series-high. See our metal detecting in Hawaii guide for the county-versus- state beach jurisdiction split and why Pearl Harbor and Hawaii Volcanoes National Park stay off-limits. Nevada, the 37th state in this series, is the most open state by land area — 80.1% federal, the highest share of any state, with BLM confirming detecting is allowed there — yet its own historic mining camps and ghost towns are explicitly closed to collecting as protected historic sites. See our metal detecting in Nevada guide for why Berlin-Ichthyosaur State Park’s preserved 1890s gold-mining ghost town makes the gap concrete, and the escalating gross-misdemeanor-to-felony penalty for disturbing a Native American grave. Idaho, the 38th state in this series, lets a state park manager authorize detecting case by case — but Boise is the first city covered so far to charge cash for that permission, a $13.50 fee instead of a free sign-off. See our metal detecting in Idaho guide for why a July 2026 law just turned disturbing a Native American grave into a felony carrying up to $50,000, the highest penalty documented anywhere in this series. New Mexico, the 39th state in this series, has the narrowest state-park exception found so far — only a committee-approved scientific project or a lost-item recovery, not general relic hunting. See our metal detecting in New Mexico guide for why the actual birthplace of the first US gold rush was private land, not a park, and why the state’s unmarked- burial statute is the first in this series to reach onto private property too. Kansas, the 40th state in this series, is the first whose governing rule never mentions a metal detector at all — it bans digging holes and removing historical material generally. See our metal detecting in Kansas guide for why that digging rule still governs the hobby, and why the state’s two penalty statutes run from a $500 misdemeanor ceiling to a $100,000 burial-disturbance fine. Rhode Island, the 41st state in this series, names a rule category — “designated areas during specified time periods” — without ever naming the areas or the periods themselves. See our metal detecting in Rhode Island guide for why even the state’s own permit process won’t tell you until you ask, and why disturbing a grave anywhere in the state is a felony carrying mandatory restitution on top of the fine. Wyoming, the 42nd state in this series, splits one rule into two tiers — a park or recreation area you can get written superintendent permission to detect at, and a state historic or archaeological site you can’t ask your way into at all. See our metal detecting in Wyoming guide for why the state’s own 1867 gold-rush town falls into the second, closed-off category. Alaska, the 43rd state in this series, is the first with no permission door at all — its own park system FAQ says flatly you may not use a metal detector in a state park, full stop. See our metal detecting in Alaska guide for why the same park system still welcomes gold panning with a pan and shovel at its own historic gold-mining camp. Montana, the 44th state in this series, is the first whose rule actually uses the words “metal detector” — most states’ park regulations only ban digging or soil disturbance and leave the hobby to be inferred. See our metal detecting in Montana guide for why that explicit ban also carries a penalty ladder found nowhere else in this series, escalating from a 48-hour expulsion up to a full year suspension across repeat violations. Louisiana, the 45th state in this series, is the first where the defining rule isn’t a standing statute at all — it’s a reversal. See our metal detecting in Louisiana guide for why New Orleans City Park banned the hobby in April 2025 after decades of allowing it, with no warning to the 2,500+ detectorists across three clubs who’d used the park for years. Delaware, the 46th state in this series, is the first whose state-park rule skips the ask-first permission path entirely — it just bans detecting everywhere except one named zone. See our metal detecting in Delaware guide for why carrying the wrong digging tool can count as evidence against you before you’ve dug anything at all. Mississippi, the 47th state in this series, is the first whose park rule cites a specific statute that, read directly, never mentions a metal detector at all. See our metal detecting in Mississippi guide for why the cited law is just a list of definitions, and why the burial-protection statute that actually has teeth reaches private land too. Nebraska, the 48th state in this series, technically allows detecting at posted swim beaches “year around” — but caps the three warmest months to a 6-9 a.m. window. See our metal detecting in Nebraska guide for why that rule and the state’s two-tier burial-disturbance penalty (a misdemeanor for not reporting, a felony for digging) are paired with the lowest federal-land share documented anywhere in this series. North Dakota, the 49th state in this series, bans any device that locates or removes metallic objects from a state park outright — no permit exists to apply for. See our metal detecting in North Dakota guide for why its burial-disturbance felony is the first in this series to hinge on motive rather than repeat offenses or which law covers the land.

City parks, county parks, and beaches: the most permissive ground

Local parks and public beaches are where most detectorists actually spend their time, and for good reason — they’re the most consistently permissive category, and it’s where our own beginner’s guide tells new hobbyists to start. City and county parks typically allow detecting in open lawn and picnic areas but ban it in memorial sections, playgrounds, and anywhere flagged as historic. Public beaches below the high-tide line are usually the single most permissive ground in the entire legal landscape — it’s also why our beach and waterproof detector guide exists as its own category. The exception worth knowing: a beach that sits inside a national seashore or a restricted state park inherits that stricter parkland’s rules, so a quick check of posted signage still matters.

Private property: always the owner’s call, no exceptions

There’s no ambiguity here at all: detecting on private property — a friend’s field, a farm, a vacant lot — always requires the owner’s permission, regardless of what state or local law says about public land. No regulation overrides a landowner’s right to say no. The community norm that keeps this door open for everyone is simple and well established: ask first, fill every hole, split any significant find with the owner if that’s the deal you struck, and you’ll almost always be invited back.

What happens if you break the rules

The consequences scale with where the violation happens. On National Park Service land, possessing a detector at all violates 36 CFR 2.1(a)(7) — expect confiscation of the device and a citation at minimum. Add an actual dig on any federal land and you’re in ARPA territory, and the numbers are specific: a first-offense felony under ARPA carries up to a $20,000 fine and/or two years in prison, and a second offense raises that to up to $100,000 and five years, per the National Park Service’s own ARPA guidance. On state and local land, penalties are typically far lighter — a warning or a citation for detecting without a permit or in a restricted zone — but repeated violations can get a detectorist banned from an entire park system. The pattern holds everywhere: the deeper you dig without checking first, the worse the consequences get.

The verdict: check the specific ground, every time

Metal detecting itself isn’t the legal question — where you’re standing is. National parks are a hard no under 36 CFR 2.1(a)(7). National forests are generally open outside archaeological sites. State parks need a permit check park-by-park. City parks and beaches are the most forgiving ground, and your own yard or land you have permission for is always fine. None of those rules require you to memorize a statute book — they require one habit: check before you swing, every time you’re on ground you don’t own.

Panning for gold by hand follows a different rulebook — recreational panning with hand tools generally qualifies as BLM “casual use” without a permit, covered in our gold panning kit guide. Meteorite collecting on BLM land has its own separate casual-use limit — 10 pounds per person, per year — detailed in our meteorite detector guide. Magnet fishing runs under a different rulebook again — legal in most states, but South Carolina bans it statewide outright — covered in our magnet fishing kit guide.
