Understanding Metal Detecting Laws by State
Metal detecting laws in the United States are a patchwork of federal, state, and local regulations. Knowing the rules before you detect keeps you legal and protects the hobby's reputation. The consequences for violations on federal or state land can include fines and equipment confiscation.
Federal Land Rules
The baseline federal rules apply to all federally managed land:
- National Parks: Metal detecting is prohibited in all National Park Service units. No exceptions.
- National Forests: Generally allowed for recreational coin shooting (searching for modern coins). Searching for artifacts is prohibited under the Archaeological Resources Protection Act (ARPA) without a permit.
- BLM Land: Similar to National Forest rules. Casual coin shooting is generally permitted; artifact removal is not.
- Army Corps of Engineers land: Policies vary by district. Check locally.
State and Local Variation
State parks, state forests, and municipal parks all have their own rules, which vary widely. Some states allow detecting in state parks with a permit; others prohibit it entirely. City and county parks may have their own ordinances. Always check before detecting on any public land.
Private Land
On private land with the owner's permission, you're generally free to detect and keep what you find. The main exceptions involve Native American burial sites and unmarked cemeteries, which are protected under various state and federal laws regardless of land ownership.
Staying Informed
The Federation of Metal Detector and Archaeological Clubs (FMDAC) maintains information about detecting legislation and can be a useful starting point. Local detecting clubs are often the best source of practical information about what's allowed in your area.
