Can I bring my magnet fishing equipment on a plane?

Usually not in the way people assume. Strong neodymium magnets are classified as UN2807 magnetized material, a Class 9 dangerous good, once the magnetic field exceeds 0.00525 gauss measured at 4.6 metres from the package. A typical magnet fishing magnet is well past that threshold, which puts it outside what passenger baggage normally permits unless it is shielded — with steel or soft iron sheeting — to bring the external field below the limit. Check with your specific airline well before you travel, and consider buying or renting at your destination instead.

Where in the UK can I legally magnet fish?

Scotland is the clearest answer. Most of the Scottish canal network is a scheduled monument, so you need Scheduled Monument Consent from Historic Environment Scotland plus permission from Scottish Canals — but a consented stretch of the Union Canal in Edinburgh is actively fished through Official Magnet Fishing Scotland. In England and Wales, Canal & River Trust waterways do not allow it at all, so anywhere else depends on the landowner's permission.

What should I do if I find something historically significant while magnet fishing abroad?

Report it. Most of the countries on this page require declaration of archaeological finds — Germany under state monument protection law, France under the Code du patrimoine, the Netherlands under the Erfgoedwet, and Canada where heritage items are treated as Crown property. Failing to declare can mean substantial fines, and in the more serious cases criminal charges.

Are there any countries where magnet fishing is completely unrestricted?

Very few, if any. Even where there is no national ban — the Netherlands and Australia are good examples — heritage law, park regulations, and municipal ordinances still apply. The realistic question is not whether rules exist but which layer of government sets them where you're going.

International Magnet Fishing Laws by Country (2026)

Updated September 2026

Short answer: magnet fishing abroad is far more restricted than it is in most of the United States. It is not allowed on the 2,000+ miles of canals and rivers run by the Canal & River Trust in England and Wales. It needs written State authorisation in France. Most German states require a permit and several ban it outright. Scotland is the one place in the UK with a formal, sanctioned agreement — and even there you need consent from two separate bodies first.

If you're looking for the U.S. rules instead, we cover those separately in our state-by-state guide to magnet fishing laws.

Heads up: This is a research summary, not legal advice. National rules, local ordinances, and park bylaws all stack on top of each other, and enforcement varies enormously. Always confirm with the waterway manager or local authority before you travel with a magnet.

What's changed

Scotland now has the UK's only sanctioned magnet fishing agreement. Scheduled Monument Consent has been granted for a defined stretch of the Union Canal, with more locations being pursued. Details below.
The Canal & River Trust position has hardened. It is a flat prohibition, not the permit system that older guides (including an earlier version of this page) described.
France's rules are being actively restated by prefectures, which have been publishing reminders that magnet fishing without authorisation is an offence under the Code du patrimoine.

Last verified: September 2026.

United Kingdom: three different answers

The UK is not one jurisdiction for this hobby. Treat England and Wales, Scotland, and Northern Ireland as separate problems.

England and Wales: not allowed on Trust waterways

The Canal & River Trust manages most of the canal network in England and Wales, and its position is unambiguous: "we don't allow magnet fishing as it can be extremely dangerous."

The Trust's stated reasoning is practical rather than archaeological:

Recovered items can be sharp or heavy enough to pull you into the water
People have brought up wartime bombs and dumped weapons
Piles of scrap left on towpaths are a hazard for families and children

This is a blanket prohibition across Trust water, not a permit scheme. The Trust points people toward its supervised Towpath Taskforce volunteering groups as the sanctioned way to help clear a canal instead.

Water outside the Trust's network — some rivers, private lakes, council-managed water — is governed by whoever owns or manages it. There is no general English law naming magnet fishing, so permission from the landowner or navigation authority is what matters.

Scotland: legal, but only with two consents

Scotland is the genuine exception, and it's the most useful thing on this page if you're planning a trip.

Most of Scotland's canal network is a scheduled monument — a 200-year-old working heritage structure protected under the Ancient Monuments and Archaeological Areas Act 1979. Magnet fishing counts as work on that monument, so it requires Scheduled Monument Consent (SMC) from Historic Environment Scotland, plus separate permission from Scottish Canals as the landowner.

Doing it without consent is unauthorised work on a scheduled monument, reportedly carrying fines of up to £50,000.

The workable route for visitors:

Official Magnet Fishing Scotland holds consent for the stretch between Leamington Lift Bridge and Hermiston Aqueduct on the Union Canal in Edinburgh, and is pursuing further consents in Glasgow and Inverness. Joining them is the fastest legal way to fish a Scottish canal.
Applying independently for SMC directly from Historic Environment Scotland is possible, but applications take up to two months.
Either way, you must contact Scottish Canals to declare where you intend to fish.

Northern Ireland

Waterways Ireland or the relevant landowner is the body to ask. There is no published open-access scheme comparable to Scotland's, so treat permission as required rather than assumed.

Germany: permit-first, with serious fines

Germany has no single national rule. Each of the 16 states (Bundesländer) sets its own, and the published summaries group them roughly like this:

Effectively banned: Bremen, Hamburg, Saxony-Anhalt (special permits occasionally possible), and Schleswig-Holstein in state waters
Permit required from the local authority: Bavaria, Berlin, Brandenburg, Hesse, Lower Saxony, North Rhine-Westphalia, Rhineland-Palatinate, Saarland, Saxony, and Thuringia
Fewer specific restrictions: Baden-Württemberg, with local rules still applying

Reporting is inconsistent for Hamburg and Mecklenburg-Vorpommern in particular — sources disagree on whether these are prohibitions, permit regimes, or largely unregulated. Confirm directly with the state authority before fishing either.

Two things drive the strictness. The first is monument protection law (Denkmalschutzgesetz): searching for objects of historical interest generally needs a research permit, and finds must be reported or surrendered. Penalties are severe — commonly cited ranges run from €50,000 to €250,000, rising to €500,000 in serious cases.

The second is ordnance. German waterways still hold unexploded WWII munitions. If you recover anything resembling a weapon or explosive, you are expected to contact the police immediately so the Kampfmittelräumdienst (bomb disposal service) can handle it. Keeping such an item carries its own penalty.

France: illegal without State authorisation

France is stricter than most people expect, and the rule is national rather than local.

Under Article L. 542-1 of the Code du patrimoine, using electromagnetic detection to search for metal objects of historical, prehistoric, artistic, or archaeological interest requires administrative authorisation granted by prefectural order. Prefectures have been publishing reminders that this covers magnet fishing.

Getting authorisation is not a formality. Applications are reviewed jointly with the regional cultural affairs directorate (DRAC) and must set out your identity, qualifications, experience, the exact search location, your scientific objectives, and how long you intend to prospect. The prefecture can withdraw the authorisation at any time.

On top of that:

Several departments have banned it outright by prefectural order — the Somme, the Ardennes, and the Alpes-Maritimes are the ones most often named. The WWI departments are heavily represented because their waterways still hold unexploded munitions.
Several cities have their own municipal bans, with Paris, Lyon, and Strasbourg commonly cited.
Nature reserves, classified archaeological sites, historic monuments, and navigable channels near dams, power stations, and ports are off-limits regardless.

Reported penalties are a fifth-class fine for operating without authorisation, and up to €7,500 for what French law treats as clandestine excavation. The department- and city-level lists above come from French detecting associations rather than a central government register, so verify with the prefecture for wherever you're going.

Netherlands: no national ban, but check your gemeente

The Dutch position is unusual: there is no national law that bans magnet fishing. The national knowledge centre for explosive war remnants states plainly that no legislation exists with which magnet fishing can be directly and effectively prohibited at a national level.

What authorities use instead are three blunter tools:

The Erfgoedwet (Heritage Act), which prohibits removing archaeological finds but is slow to enforce
Emergency ordinances, limited in area and duration
The APV — the municipal general local ordinance — which is the practical route, because police and municipal enforcement officers can act on it directly

A growing number of municipalities have restricted or banned magnet fishing through their APV, and the list changes year to year as councils amend them. Because it's genuinely municipality-by-municipality, the only reliable answer is to look up the current APV for the specific gemeente you're visiting. Explosive finds are handled by the EOD, the Dutch bomb disposal service.

Canada: fine federally, banned on historic canals

There is no federal Canadian law against magnet fishing and no national licence. The significant restriction is a specific one:

Magnet fishing is strictly forbidden in Parks Canada's historic canals — the Rideau, Trent–Severn, Chambly, Saint-Ours, Carillon and others — under section 11.2 of the Historic Canals Regulations. Parks Canada cites three reasons: disturbing canal beds stirs up contaminated sediment at sites with an industrial past, recovered objects can be dangerous, and canal infrastructure and archaeological remains can be damaged. Non-compliance is an offence and may result in fines.

Beyond that, national parks, provincial parks, and conservation areas each set their own rules, and many prohibit removing objects of any kind from the ground or water. Provincial heritage law also applies: anything of genuine historical or archaeological significance is generally treated as Crown property rather than yours to keep.

Australia: no named law, plenty of overlapping ones

No Commonwealth, state, or territory law names magnet fishing specifically. Several general frameworks catch it anyway:

State heritage law, such as the Heritage Act 1977 (NSW), makes removing items of historical significance unlawful
The Underwater Cultural Heritage Act 2018 protects wreck remains and associated articles that have been in Australian waters for at least 75 years
Park regulations in New South Wales, Queensland, South Australia, Tasmania, and the Northern Territory expressly prohibit metal detectors and, more broadly, digging, disturbing, or removing objects
Environmental law, such as the Environmental Protection Act 1994 (QLD), can restrict activities that disturb waterways

Many Australian waterways are managed by local councils or sit on private land, so permission is usually the deciding factor rather than any statute.

United States

Regulations vary dramatically by state, and the picture is much more permissive than most of the countries above — magnet fishing is legal in 49 of 50 states. We keep the full breakdown in our state-by-state guide to magnet fishing laws, including which states need permits and what you can legally keep.

If you find ordnance

This is the one section that matters everywhere, and it's why several of the countries above restrict the hobby at all. European waterways in particular still hold live WWI and WWII munitions.

If you pull up something that could be a shell, grenade, mortar, or any unidentified military object:

Do not move it, transport it, or put it in your vehicle. Do not attempt to clean it.
Put it down gently, away from the water's edge if it is already out, and move well back.
Note the location and call the local emergency number.
Wait for the bomb disposal service — Kampfmittelräumdienst in Germany, EOD in the Netherlands, the local prefecture's service in France, police elsewhere.

The same principle applies to firearms: report them rather than keeping or moving them. Our guide on what to do if you find a gun while magnet fishing covers the U.S. procedure in detail, and the report-don't-keep rule travels well.

Practical tips for magnet fishing abroad

Ask the waterway manager, not a forum. Canal and river networks almost always have a single managing body, and they will answer a direct question.
Get permission in writing where a permit scheme exists. It is the difference between a conversation and a fine.
Check the local ordinance layer. In the Netherlands and France especially, the national position and the municipal position are different things.
Join a local group. In Scotland it is the practical route to legal access; elsewhere it is the fastest way to learn what is actually enforced.
Plan your gear around the flight — see the FAQ below, because this catches people out.

The bottom line

The instinct to pack a magnet with your luggage is the thing to reconsider. In most of the countries covered here, the default is that you need permission and the burden is on you to get it before you arrive. Scotland has shown that a properly consented arrangement is possible, and that is the model worth watching — but it took formal agreements with two separate bodies to get there.

When in doubt, ask first. Authorities are generally reasonable with people who approach them respectfully and can show they understand the safety and heritage concerns behind the rules.
