Illinois Skeleton Key Value Guide
Skeleton Key is a realistic Illinois detector target tied to fairgrounds, schoolyards, and plowed farmsteads.

Illinois state guide
Metal detecting in Illinois is usually governed by who manages the ground rather than by one blanket statute. Municipal beaches and local parks may allow it, while archaeological sites, battlefields, historic structures, and many state park units are restricted or off limits. That matters in fairgrounds, park lawns, and old canal or rail sites.
