Magnet​‍​‌‍​‍‌ fishing has become a very popular hobby. Fans basically mix components of a treasure hunt, a cleanup of the environment, and an outdoor adventure in one activity. But as the popularity rises so do the questions regarding the legality of magnet fishing: Is magnet fishing legal in your area?

The simple answer to this is: it varies, and depends on several things.

The regulations are quite different at each level of federal, state, and local government, and they may also be affected by the laws concerning the environment, archaeology, salvage, and trespassing. ​‍​‌‍​‍‌

In this article, we will talk about the following things:

• What is magnet fishing?
• Is magnet fishing legal?
• State-by-state laws related to magnet fishing.
• Common legal risks associated with magnet fishing.

Therefore, if these are a few things that you want to know about, keep on reading this article till the end…

What Is Magnet Fishing And Why Laws Apply

Just​‍​‌‍​‍‌ like anglers cannot do without specialized gear – from fly tying hackle to custom lures – magnet fishers use powerful neodymium magnets to retrieve metal objects from rivers, lakes, and canals. The procedure, although seemingly easy, is subject to a surprising number of laws and regulations.

• Environmental protection: Disturburbing sediments, taking objects from water streams, or hauling up hazardous materials (e.g., weapons, unexploded ordnance, toxic scrap) can lead to the involvement of environmental laws.
• Archaeological/historic preservation: A large number of waterways are the home of the archaeological/ historic objects that have been submerged. As per Magnet Fishing Is Fun, it is often the case that laws prohibit the taking of artifacts without proper authorization. 
• Trespass and property rights: These may be the limitations of private property access, or restrictions of state/federal land. Most of the time getting the permission from the property-owner or agency is necessary.
• Federal vs. state jurisdiction: Even though there is no single federal ban on magnet fishing, there are federal statutes (e.g., the Archaeological Resources Protection Act (ARPA), the Clean Water Act) that may come into play while state/local law help pinpoint the details.

Apart from South Carolina, which is the only state that bans magnet fishing, experts mention that in other states magnet fishing is permitted, but there are different rules regarding the artifacts ​‍​‌‍​‍‌found.

Federal Vs. State Oversight

From​‍​‌‍​‍‌ a federal vantage point, there is no single nationwide law which prohibits magnet fishing in all situations. Nevertheless, a few federal laws may be relevant in certain areas:

• ARPA is a law that protects archaeological resources on lands that are federal or belong to Native Americans. 
• The Clean Water Act forbids unauthorized discharges or disturbances of navigable waterways.
• Some federal properties (military installations, national parks) may disallow magnet detecting/fishing based on their recreation/use policies. For example, the United States Army stated that magnet detection was considered illegal at Fort Stewart according to the installation’s recreation policy.

As states and localities control the access to waters, removal of artifacts, rights of trespassing, and property rights, a hobbyist has to look up state law + local regulations (city/county too) even if federal law is silent on magnet ​‍​‌‍​‍‌fishing.

State-By-State Magnet Fishing Laws

Below is a summary of how states approach magnet fishing, structured into four categories for easier scanning. Because statutes shift and local rules vary, this should be used as a reference point—not legal advice.

A. States Where Magnet Fishing Is Generally Legal (With Caveats)

In many states, magnet fishing is legal and permitted, provided you have permission for the land/water access and avoid protected archaeological sites. Examples:

• Texas
• Florida
• California

B. States Requiring Permits Or Permissions

Some states allow magnet fishing but impose extra requirements (permits, fishing licenses, or restrictions on artifact removal).

• Michigan
• Illinois
• Pennsylvania

C. States With Significant Restrictions Or Ambiguities

In this group, states do not outright ban magnet fishing, but the laws are unclear or heavily regulated.

• New York
• Ohio
• North Carolina

D. States Where Magnet Fishing Is Prohibited Or Highly Restricted

There is at least one state that explicitly bans the activity in certain contexts.

• South​‍​‌‍​‍‌ Carolina: Magnet fishing is not legal here. It is a part of an activity that is not allowed by the Underwater Antiquities Act. In general, one cannot remove (by use of any device from the surface) artifacts from state waters in an indiscriminate way. ​‍​‌‍​‍‌

Common Legal Risks & How To Stay Compliant

In​‍​‌‍​‍‌ any case, pattern legal risks accompany magnet fishing across states. Knowing them makes you keep your fingers on the safer side:

• Trespassing: Performing magnet fishing on private lands or waterways without the consent of the owner may result in you being held liable in a civil or criminal case. Be sure to get the owner’s consent or make use of public access areas.
• Artifact/heritage protection: Discovery of an item can lead to a number of legal obligations if the item is of historical/archchaeological significance (reporting, forfeiture). In some places, it is a crime to take an item without a permit.
• Unexploded ordnance / dangerous objects: Magnet fishing can be the cause of the detachment of weapons, bombs, ammunition, or other toxic materials. These may be under the jurisdiction of law enforcement or military authorities, as stated by Green Matters.
• Environmental disturbance: Changing the sediments, aquatic habitats, or taking away huge metal pieces may be considered breaking environmental laws (such as the Clean Water Act) that protect the water and other natural resources.
• Unknown ownership / salvage rights: Getting hold of things from underwater lands or public waters can be a matter of salvage law or abandoned property law – just because you are the one who retrieved something does not always mean you can keep it. ​‍​‌‍​‍‌

Practical Tips For Responsible Magnet Fishing

To maintain the hobby in a responsible, legally safe and environmentally respectful way, consider the following:

• Research first: Before heading out, check state environmental agency websites, local park rules and water-use statutes.
• Pick non­sensitive sites: Avoid historical battlefields, known archaeological areas, or waterways with restricted access.
• Respect the ecosystem: Retrieve your finds, carry away scrap metal or other debris, leave no trace. Some magnet fishers frame the activity as “clean-up with a magnet”.
• Report large or dangerous finds: If you pull up unexploded ordnance, firearms, or items with serial numbers, alert the police or local authority.
• Keep records: Log your location, date, permission status and finds — if challenged later you have a record of your precautions.
• Stay updated: Laws and rules change. What was allowed last year may now be restricted.

Is Magnet Fishing Legal? Know Before You Throw

As​‍​‌‍​‍‌ a rule, magnet fishing can be a great, green-loving pastime with a little bit of treasure hunting thrown in the mix. However, it’s not a “free for all.” The question of its legality is largely dependent on your location, the manner in which you get to the water, and what you haul out.

It is true that a considerable number have U.S. states permit magnet fishing in some capacity, but you are still required to take into consideration property rights, environmental conservation, laws relating to the historical artifacts, and local ​‍​‌‍​‍‌regulations. Disclaimer: This article offers a survey of the key issues and a state-by-state snapshot (as of now). But it is not legal advice. If you plan to magnet fish, especially in a location with public or historic significance or with a potential commercial motive, you should consult the relevant state agency or seek legal counsel.
