Maine metal detecting rule layers
Quick answer: a rule applies because of jurisdiction and managing authority, not simply because a place is publicly accessible. This page contains only rule layers actually inherited by current Maine records.
How to read these rules: detector use, digging, target recovery, artifact protection, permits and designated zones can be controlled by different provisions. A restrictive recovery rule is not automatically rewritten as a detector-possession ban, and an access permit is not automatically treated as recovery authorization.
Maine metal detecting law questions
Is metal detecting legal on all public land in Maine?
No. Public access does not create metal-detecting or target-recovery permission. The controlling rule depends on the land manager, property purpose, detector-use rule, digging/recovery restrictions, protected-resource law and any permit or designated-zone requirement.
Does a recreation, hunting or access permit authorize metal detecting?
Not unless the controlling rule expressly says it does. Access credentials and detector/recovery authorization are treated as separate legal questions in this database.
Can a map pin prove where metal detecting is permitted?
No. A map pin is only a public visitor/access reference point. It is never treated as a property boundary, detecting zone, archaeological location or legal permission boundary.
How many controlling rule layers are listed for Maine?
12 current rule layers are represented on this page. Each rule entry identifies its managing authority, status, official source, verification grade and verification date.

Maine MDIFW Wildlife Management Areas
MDIFW states WMAs are generally open for recreation, but the current WMA materials do not create a blanket metal-detecting/digging authorization. Because hunting, fishing, boating or wildlife-watching access is activity-specific, detector use and recovery remain confirmation-gated; Maine Antiquities Law separately protects qualifying archaeological sites on State-controlled land.
Important exceptions: Steve Powell (Swan Island) has an express detector prohibition and is classified separately.

Maine municipal park/beach systems
No statewide Maine State Park detector permit applies to municipally managed property. Verify current municipal ordinances, posted rules and recovery/disturbance permission before detecting.
Important exceptions: Beach access, park hours or general recreation permission is not detector permission.

Maine Public Reserved Lands / other Bureau Public Lands
Public Lands rules prohibit damaging natural features and require designated cultural resources/preserves to remain undisturbed. Bureau permit guidance says activities that alter or remove anything from Bureau-owned land exceed normal recreation and require a permit or license.
Important exceptions: Do not project the State Park detector-permit rule onto Public Lands; obtain the exact Bureau determination for detecting and recovery.

Maine State Historic Sites
Maine State Park Rule 4 expressly prohibits use of metal detectors at historic sites.
Important exceptions: No recreational detector pathway is represented for State Historic Sites.

Maine State Parks
Maine State Park Rule 4 prohibits metal detectors at historic sites and allows detectors in other covered park areas only by written permit obtained at the park. Rule 1 separately protects natural, physical, prehistoric and historic resources from removal or damage.
Important exceptions: A written detector permit must control the exact area and conditions; it does not override archaeology/resource protections.

Mixed-ownership NPS-associated trail/corridor property in Maine
The Appalachian Trail crosses NPS, Forest Service, State, nonprofit and other ownership. Direct NPS-administered property follows 36 CFR 2.1 metal-detector restrictions; other parcels follow their actual owner/manager rule.
Important exceptions: Never apply the NPS detector prohibition to the entire trail corridor without parcel ownership confirmation.

National Park Service park areas — 36 CFR §2.1
36 CFR §2.1 prohibits possessing or using metal detectors and related detecting devices in National Park Service park areas. The same section also prohibits digging, disturbing, removing or damaging protected natural, cultural and archaeological resources. current data uses this federal rule only for public visitor/reference points inside identified Florida NPS units; no search-target coordinates are exposed.
Important exceptions: The detector prohibition does not apply when a device is broken down and packed to prevent use, to navigation/safe-operation equipment for boats or aircraft, or to detectors used for authorized scientific, mining or administrative activities. These are not ordinary recreational detecting permissions. Park-specific closures and superintendent rules may be stricter.

Steve Powell Wildlife Management Area (Swan Island and Little Swan Island)
MDIFW Swan Island visitor rules expressly state that metal detectors are not allowed to be used on Swan Island or Little Swan Island.
Important exceptions: None for ordinary recreational metal detecting.

U.S. Fish & Wildlife Service National Wildlife Refuge System — 50 CFR Part 27 search/resource restrictions
Federal Refuge System rules provide an A-grade negative decision for antiquity, buried-treasure/treasure-trove, specified mineral-object and prospecting searches and for unauthorized property disturbance/removal. They do not expressly answer every ordinary modern lost-item detector-use scenario. current decision therefore publishes the resolved restrictions while preserving the unresolved narrower detector-use dimension.
Important exceptions: Refuge-specific rules, closures, special-use permits and compatibility determinations may be stricter, including explicit detector prohibitions. Authorized activities may exist under applicable federal regulations. No permission is inferred from public access, beaches, waterways or absence of a refuge-specific detector sentence.

White Mountain National Forest lands in Maine
Forest Service guidance allows certain recreational metal detecting for recent lost objects where not otherwise prohibited, while archaeological/historic resources, protected sites and activities amounting to archaeological excavation remain restricted.
Important exceptions: Local orders, wilderness/resource protections and exact land status control.
