Washington 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 Washington 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.
Washington metal detecting law questions
Is metal detecting legal on all public land in Washington?
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 Washington?
15 current rule layers are represented on this page. Each rule entry identifies its managing authority, status, official source, verification grade and verification date.
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.

Natural areas are managed primarily to protect ecosystems and sensitive resources, so the ordinary DNR metal-detecting allowance is not treated as blanket permission in these conservation systems.
Important exceptions: Check the exact natural-area rules, posted closures and manager direction before any soil-disturbing activity.
