On state park land
Allowed in some places
On designated swimming beaches operated by the Maryland Park Service, excluding Point Lookout and Calvert Cliffs, with permission from the Service. Barred 9 a.m. to dusk from 30 May to Labor Day, AND at other times at the park manager's discretion.
Those three narrowings are individually unremarkable and together they close most of when you would want to go.
1. The rule, in full
Maryland – COMAR 08.07.06.18
Read from the official Code of Maryland Regulations published by the Division of State Documents (dsd.maryland.gov), regulation 08.07.06.18 in full. Re-read 3 Oct 2026, and it corrected two things set out below.
Corrected 3 Oct 2026. The previous version named the wrong body for the permission and omitted one of the two exception windows. Recorded in SOURCING-AUDIT.md.
Operative text, 08.07.06.18 "Relics, Treasures, and Metal Detectors":
A. "The policy of the Service is to safeguard the archeological resources under its care."
B. "Without a permit from the Office of Archeology, Maryland Historical Trust, Department of Housing and Community Development, and the Department, an individual may not dig in search of buried relics or treasures, remove prehistoric or historic artifacts, or use metal detectors, except as provided in D."
D. "Metal Detector Exception.
(1) An exception to the permit requirements of this regulation is for the use of a metal detector in the search for modern coins, jewelry, and other items on designated swimming beaches operated by the Service, with the exceptions of Point Lookout and Calvert Cliffs.
(2) An individual shall obtain permission to use a metal detector as set forth in this regulation from the Service.
(3) A metal detector may be used during normal park hours with the following exceptions:
(a) 9 a.m. through dusk from May 30 through Labor Day; and
(b) Other times at the discretion of the park manager."
The two corrections, because both change what a reader should do.
Permission comes from the Service, not the park manager. D(2) says "from the Service" – the Maryland Park Service. The previous entry sent readers to the Park Manager. The park manager appears in this regulation only in D(3)(b), and for a different purpose.
The published window is not the whole answer. D(3) gives two exceptions to normal park hours, and the entry carried only the first. Besides the 9 a.m. to dusk closure from 30 May to Labor Day, D(3)(b) allows closure at "other times at the discretion of the park manager". So a reader who checks the calendar and the clock can still be turned away, and the page now says so rather than implying the season and the hours settle it.
Two smaller fixes inside the quotation marks: the rule says "designated swimming beaches", not "all designated swimming beaches", and "9 a.m.", not "9:00 a.m.".
A second regulation, same title, different agency: COMAR 34.04.08.25
Added 8 Oct 2026. Found by chasing a reference URL on the Maryland post, which stated this rule's substance without its number.
COMAR 34.04.08.25, "Relics, Treasures, and Metal Detectors" – note the title is identical to 08.07.06.18's:
A. "A person may not dig in search of buried relics or treasure, remove any prehistoric or historic artifacts, or use a metal detector within the boundaries of a State museum unless the person first obtains a permit from the Maryland Historical Trust, and express permission from the museum director."
B. "The museum director may grant permission under SectionA of this regulation only to archaeologists and other qualified persons or institutions experienced in scientific research, who present a plan for scientific investigations, as provided by State Finance and Procurement Article, Title 5A, Subtitle 3, Part IV, Annotated Code of Maryland."
Two permissions, not one. A Trust permit is not enough inside a State museum; the museum director must also agree. And (B) states the test the director applies, which no other Maryland instrument spells out: archaeologists and qualified researchers with a scientific plan.

MHT's own page, and the reporting question
Read from the Maryland Historical Trust at mht.maryland.gov, identify-document/report-artifact-discovery/metal-detecting-maryland, 8 Oct 2026. Agency policy, dated separately from the regulations above.
The Trust confirms the regulatory picture and settles one thing no regulation addresses:
"If you find something that appears to be more than 50 years old, like evidence of an old historic site or other historic activity, please report it to MHT. Your report helps us document significant places in the Maryland Inventory of Historic Properties (Archaeology)."
That is a request, and the page must not restate it as a duty. Secondary guides routinely turn it into "items over 50 years old must be reported", including on private land. No provision of COMAR 08.07.06.18, COMAR 34.04.08.25, 5A-340 or 5A-342 imposes a reporting obligation on a finder, and MHT itself says that on private land items "generally belong to" the landowner.
Also from the same page, and useful:
"Metal detecting on state-owned land requires an archaeology permit from MHT, which is usually reserved only for professional archaeologists." "MHT does not issue permits for metal detecting on private, federal, or local land."
Note the two permissions a reader will otherwise conflate: the MHT archaeology permit is what you do NOT need at a designated swimming beach; the Service's permission under D(2) is what you DO need.
Scope. COMAR 08.07.06 is "Use of State Parks". DNR's own page states the prohibition runs to "lands, beaches, or under waters controlled by the Maryland Park Service".
Determination: Maryland Park Service land only. Does NOT reach municipal parks.
The statute was checked separately, because Maryland's archaeological statutes do use the phrase "political subdivision" and that is exactly the shape that caught Kansas. It does not reach here:
Md. Code, State Fin. & Proc. 5A-342(a): "Without a permit, a person may not excavate, remove, destroy, injure, deface, or disturb a terrestrial archaeological site on land that the State owns or controls."
Md. Code, State Fin. & Proc. 5A-340(a): "Submerged archaeological historic property on or taken from underwater land over which the State has sovereign control is the property of the State."
"[L]and that the State owns or controls" does not reach a city park. The "political subdivision" definition in Part IV governs who may be a party to Trust agreements, not whose land the permit requirement covers. Recorded so the next person does not have to re-check it.
Exception worth carrying to the page verbatim: the designated-swimming-beach carve-out is one of the few genuinely permissive state-park provisions found so far, and it is narrowed three ways – modern coins and jewellery only, two named parks excluded, and a seasonal daytime blackout.

What was read for the land-class sweep, and what was not. Read: COMAR 08.03.02.18 and the definitions at 08.03.02.01. Not read: the remainder of COMAR 08.03, which was reached by search rather than read. The finding above therefore covers what was read and nothing beyond it – see sweep/README.md, "A KNOWN LIMIT OF THIS SWEEP", on why a chapter set aside on its title is an unread chapter.
The rulemaking statute, which is wider than the regulation and carries a condition
COMAR 08.07.06.18 is a State Park Service regulation. The statute it was made under says which land the Department may regulate, and the list is longer than "state parks":
Md. Code, Natural Resources 5-209(a): "The Department may make rules and regulations for the maintenance of order, safety, sanitation, traffic control, or for the protection of trees and other property and the preservation of the natural beauty within the State parks and forests, State reserves, scenic preserves, parkways, historical monuments, recreational areas, and any other lands under its control. The rules and regulations shall be posted in conspicuous places upon the lands and enforced by the forest and park officers."
Two things in that sentence matter to a detectorist. The authority covers state forests, reserves, scenic preserves, parkways and historical monuments as well as parks, so a Maryland reader cannot narrow the question to a park boundary. And the rules "shall be posted in conspicuous places upon the lands" – a posting requirement written into the statute itself, which is unusual in this directory and is worth a reader's attention, because it means the regulation's own enabling act contemplates the visitor being told on site.
The penalty was looked for and not found, and that is recorded rather than filled in
No penalty appears in any Maryland source this project holds. The word "penalt" occurs zero times across every archived Maryland document: COMAR 08.03.02.01, COMAR 08.03.02.18, COMAR 08.07.06.18, COMAR 34.04.08.25, the Maryland Historical Trust metal-detecting page, and Natural Resources 5-209, 5-210, 5-212 and 1-704 as read on 18 Oct 2026. "Misdemeanor" occurs zero times in the four statute sections read.
So this entry states the prohibition and the permit requirement and does not state a consequence, because none has been located in an official Maryland source. A reader should not read that silence as meaning there is none – it means the grading section has not been found. The section list of Natural Resources Title 5 has not been walked end to end, which is the obvious next step and is recorded in manual-capture.md under "Maryland" with the URL pattern that works.
A retrieval note, because this one cost time. mgaleg.maryland.gov's Laws/StatuteText?article=gnr§ion=<n> route returns the site's navigation chrome with "Bill number does not exist" for every section tried, whatever the section. The route that works is the statute PDF:
https://mgaleg.maryland.gov/2026RS/Statute_Web/gnr/5-209.pdf
Substituting the section number in that path returns the section as published. Anyone extending this entry should start there rather than with the HTML route.
Deepened 18 Oct 2026. Md. Code, Natural Resources 5-209, 5-210, 5-212 and 1-704 read that day from mgaleg.maryland.gov, the Maryland General Assembly's own statute service, and archived with their sha256.

Baltimore
Permission needed
A Metal Detector Permit is required for individuals who wish to use metal detectors in Baltimore City Parks. … Applicants must be at least 16 years old and present a government-issued photo ID. Completion of a training session from a recognized metal detecting club is mandatory. A $25 fee (payable via Money Order or Credit/Debit Card) is required for issuance and yearly renewal. … Digging deeper than 8 inches is prohibited, and all holes must be properly restored. Certain locations, including Carroll Park, Federal Hill Park, and the Inner Harbor, are off-limits. Metal detecting is prohibited in July and August each year.

3. County rules
County rules exist in Maryland, and they govern county land only. 3 county rules surfaced while checking cities in this state. Each was read and then set aside, because a county park rule does not answer whether a city park allows detecting, and it is not the state rule either. They are listed because their existence is the useful fact: if you are in a county park, a separate rule probably applies to you.
| Surfaced while checking | What the county rule does | County or source |
|---|---|---|
| Aberdeen | Prohibited | harfordcountymd.gov source, county not named |
| Bel Air | Prohibited | harfordcountymd.gov source, county not named |
| Havre de Grace | Prohibited | harfordcountymd.gov source, county not named |
4. Cities checked - no published rule
23 cities in Maryland were checked and have no published rule on this page. Of those, 20 returned no rule, and 3 did return something that has not been published – mostly rules that turned out to govern county land, which are in the county section above. A city here is not a city where detecting is allowed. It is a city whose own published material did not answer the question.

6. Land this page does not cover
This page answers for Maryland state land, and for city and county land where the state rule reaches it. Several other kinds of ground are not covered here, and naming them is more honest than letting a reader assume the page is complete.
Tribal land. This directory does not cover it, and will not.
There are 574 federally recognised tribal nations. Each is a sovereign jurisdiction with its own law, its own permitting, its own enforcement and its own cultural-resource provisions, and none of them is answered by a state's code or by any federal rule quoted on these pages. A one-line instruction to "get tribal permission" would be worse than this paragraph, because it implies one process and one authority where there are 574. If you are on or near tribal land, the governing law is that nation's, and the place to ask is that nation's own offices. Nothing on this page applies there.
BLM land is covered, partly, in its own place. The Bureau of Land Management holds about 245 million acres and the federal rule names metal detectors and permits them, which is the opposite of the national park rule. See BLM land: the detector is named, and permitted. That page covers the base regulation; it does not yet cover the supplementary rules individual BLM State Directors issue for particular field offices.
Named and not examined. These are recorded so their absence is visible rather than silent. No claim is made about any of them:
- Military withdrawn land, including ranges and training areas.
- Bureau of Reclamation land, which surrounds a great many reservoirs.
- Water district and irrigation district land.
- Wilderness, Wilderness Study Areas and National Conservation Areas, which carry designations of their own. And one general point about signs. The commonest piece of reasoning in this subject is "there was no sign, so it was allowed." Arizona's State Land Department answers it in writing, in condition 2 of its own Recreational Permit terms:
"You will comply with all laws, rules, regulations and ordinances. Posting is not required for these provisions to be enforceable."
That is Arizona's sentence about Arizona's provisions and this directory does not present it as the law of any other state. But the proposition it states is the one to carry: nothing read for this project makes a published rule's enforceability depend on a sign at the boundary. Where posting does matter, a specific provision says so, and that provision is quoted on the page where it occurs.
