Here are some general rules of thumb for where to use your metal detector (United States only). Keep in mind that it is ALWAYS best to check and make sure you have permission before you start!
National Forest and Federal Lands
No metal detecting allowed unless you have a special permit from the federal government. Each area has its own district office; you may contact them to request permission.
Visit the National Forest Service website.
Visit the National Park Service website.
Corps of Engineers, Lakes, Shorelines and Lands
Metal detecting is allowed on “predisturbed” sites. Detecting on new land or lakes must be approved by the main office of the Army Corps of Engineers.
Visit the Army Corps of Engineers website.
State Parks and Lands
This varies from park to park. Always check with a park ranger before using your metal detector.
Learn about your State Parks.
Bureau of Land Management (BLM) Lands
This varies; some lands are open for metal detecting, and some are not. Check with your district office.
Visit the Bureau of Land Management website.
City or County Park Lands
Most city and county park lands are open for metal detecting, unless a sign or city ordinance is posted that says otherwise. Check with your city's Parks and Recreation department.
Public School Grounds
Most public school grounds are open for metal detecting, unless a sign or ordinance is posted that says otherwise, or a law enforcement official or school employee says otherwise. Check with the school office before you begin.
Privately Owned Lands (Private Property)
It's easiest to search on private property, but always have permission first, preferably in writing.
Historically Marked Lands or Sites
No metal detecting, period.
