Status: metal detecting is restricted to designated areas (often beaches) in state parks.
Michigan DNR allows metal detecting only within areas of state parks/recreation areas specifically designated (marked) as open to it - it's prohibited outside those designated zones and at historic/archaeological sites. Hand trowels/probes are OK for small digs (fill holes back in); large-scale digging needs a separate archaeological permit.

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 Michigan.
Getting permission on private land
Most of the best ground in Michigan - 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.

Federal BLM land and most National Forests generally allow casual hobby detecting for modern items (never on archaeological sites or anything over 100 years old, per ARPA). All other land - including private property - requires the landowner's or managing agency's permission. WhereToDetect's map gives a per-spot land status.
