Illinois metal detecting rule layers
Quick answer: a rule applies because of jurisdiction and managing authority, not simply because a place is publicly accessible. This page contains only rule layers actually inherited by current Illinois records.
How to read these rules: detector use, digging, target recovery, artifact protection, permits and designated zones can be controlled by different provisions. A restrictive recovery rule is not automatically rewritten as a detector-possession ban, and an access permit is not automatically treated as recovery authorization.
Illinois metal detecting law questions
Is metal detecting legal on all public land in Illinois?
No. Public access does not create metal-detecting or target-recovery permission. The controlling rule depends on the land manager, property purpose, detector-use rule, digging/recovery restrictions, protected-resource law and any permit or designated-zone requirement.
Does a recreation, hunting or access permit authorize metal detecting?
Not unless the controlling rule expressly says it does. Access credentials and detector/recovery authorization are treated as separate legal questions in this database.
Can a map pin prove where metal detecting is permitted?
No. A map pin is only a public visitor/access reference point. It is never treated as a property boundary, detecting zone, archaeological location or legal permission boundary.
How many controlling rule layers are listed for Illinois?
12 current rule layers are represented on this page. Each rule entry identifies its managing authority, status, official source, verification grade and verification date.
Illinois
IDNR requires a metal detecting permit at sites that allow the activity. The site superintendent designates the permitted area; recovery tools are limited and designated-beach detecting is sunrise to 10 a.m.
Important exceptions: Not all IDNR sites allow detecting. No detecting is allowed on State Historical, Archaeological or Nature Preserve sites; site superintendents may impose stricter limits.

The current IDNR metal-detecting permit expressly prohibits metal detecting on any State Historical, Archaeological or Nature Preserve site.
Important exceptions: Where a larger recreation property contains a protected sub-area, that protected portion remains closed even if detecting is authorized elsewhere.

Current site-specific IDNR pages expressly prohibit metal detecting at the listed property or complex.
Important exceptions: Site-specific prohibitions override the general permit pathway.

These conservation properties may contain Nature Preserve or other protected parcels. Public access or hunting does not establish detector-recovery permission.
Important exceptions: Any State Nature Preserve portion is expressly closed by the current IDNR metal-detecting permit.

Shawnee Forest Plan guidance restricts visitor metal-detector use to developed recreation sites not associated with heritage-resource sites.
Important exceptions: Historic, prehistoric, archaeological, wilderness, natural-area and other sensitive-resource locations remain protected; treasure/heritage searches can require federal authorization.

Midewin is a restored federal prairie on the former Joliet Army Ammunition Plant landscape. Ordinary public access is not treated as blanket excavation or detector-recovery permission.
Important exceptions: Confirm current Forest Service rules, closures, former-munitions restrictions and heritage-resource protections before detecting.

National historic trails cross multiple ownerships; the NPS detector prohibition applies on NPS-controlled land, while non-NPS parcels follow the actual owner rules.
Important exceptions: Do not infer NPS ownership from the trail corridor alone.

USACE recreation access does not establish blanket detecting permission; current project rules and 36 CFR Part 327 control detector use and resource protection.
Important exceptions: Historic and archaeological resources remain protected and local project orders can be stricter.

Local public access does not itself establish permission to use a detector or disturb turf, beaches or protected resources.
Important exceptions: Check the current ordinance, park rules and exact ownership before detecting.

National Park Service park areas — 36 CFR §2.1
36 CFR §2.1 prohibits possessing or using metal detectors and related detecting devices in National Park Service park areas. The same section also prohibits digging, disturbing, removing or damaging protected natural, cultural and archaeological resources. current data uses this federal rule only for public visitor/reference points inside identified Florida NPS units; no search-target coordinates are exposed.
Important exceptions: The detector prohibition does not apply when a device is broken down and packed to prevent use, to navigation/safe-operation equipment for boats or aircraft, or to detectors used for authorized scientific, mining or administrative activities. These are not ordinary recreational detecting permissions. Park-specific closures and superintendent rules may be stricter.

U.S. Fish & Wildlife Service National Wildlife Refuge System — 50 CFR Part 27 search/resource restrictions
Federal Refuge System rules provide an A-grade negative decision for antiquity, buried-treasure/treasure-trove, specified mineral-object and prospecting searches and for unauthorized property disturbance/removal. They do not expressly answer every ordinary modern lost-item detector-use scenario. current decision therefore publishes the resolved restrictions while preserving the unresolved narrower detector-use dimension.
Important exceptions: Refuge-specific rules, closures, special-use permits and compatibility determinations may be stricter, including explicit detector prohibitions. Authorized activities may exist under applicable federal regulations. No permission is inferred from public access, beaches, waterways or absence of a refuge-specific detector sentence.
