Land you can usually detect without asking
Casual hobby detecting for modern coins and jewelry is generally allowed on BLM public land and in most National Forests - but never on archaeological sites, and anything over 100 years old is federally protected (ARPA). National Parks are completely off-limits. Everything else, including all private land, needs permission. The map shows which is which for any spot in Maryland.
Getting permission on private land
Most of the best ground in Maryland - vanished farmsteads, early school sites, old picnic groves - is private. The proven approach: bring a specific historical reason ("the 1890s map shows a schoolhouse in your field"), promise to fill every hole and haul out trash, and offer the owner first look at finds. WhereToDetect generates the permission letter, looks up the county parcel office, and tracks every ask for you.
