The 50-state metal detecting atlas
Metal Detecting Places, Maps & Laws Across All 50 States
Quick answer: metal detecting legality depends on the exact managing agency, recovery method, protected-resource rules, permit requirements and any designated-zone restriction. Search the nationwide evidence database without treating public ownership, a park name or a map pin as permission.

How to use a metal detecting decision page
- Identify the exact place and managing agency rather than assuming all public land has the same rule.
- Read the detector-use, digging/recovery, artifact and permit rules together.
- Use the cited official source and verification date to confirm the rule is still current before travel.
- Treat every map point as navigation/reference only unless the written rule independently defines an allowed detecting zone.
Built for real trip decisions
A map, a rule trail and a next action on the same page
Records identify the controlling agency instead of assuming every public park, beach or forest follows one statewide rule.
Permission to carry or operate a detector is not confused with permission to dig, remove a target or keep a protected object.
Every decision page preserves its verification date, evidence grade, confidence score and official source links.
Verified pins, temporary search matches and planning overlays are labeled so navigation never silently becomes a permission claim.
U.S. metal detecting questions, answered
Where can I legally metal detect in the United States?
There is no universal public-land permission. Start with the exact property and managing agency, then confirm detector use, digging and recovery, protected-resource rules, permits, closures and designated zones before travel.
Does the metal detecting map show legal detecting zones?
No. Verified pins show independently grounded public visitor or access reference points. Temporary search matches and BLM planning overlays are context only; written rules and exact property boundaries control.
Can I use a metal detector in a state or national park?
Rules vary by system and property. Many state parks prohibit detecting, require written permission or limit it to designated beaches. National Park Service units generally protect resources from detector use and removal. Always check the cited current agency source.
How current is this database?
Each location page displays its own verification date, evidence grade, confidence score and official source links. Conditions can change after review, so recheck the cited agency page and posted rules before every trip.
Is metal detecting permission the same as permission to dig or keep a find?
No. Detector use, ground disturbance, target recovery and ownership of a find can be governed by different rules. This atlas keeps those questions separate on every decision page.
Machine-readable public data
The same verified location inventory is available as JSON for research, verification and reusable data workflows. The API preserves the written legal status and suppresses unpublished coordinates; sensitive unmapped records do not expose an exact street address through the public dataset.
