Can I detect here? Start with these three checks
- Municipality: Check the current General Local By-law (APV) and any additional prohibited areas.
- Landowner: Obtain permission from the owner or other authorised person, and check the land manager's rules.
- Archaeology: Find out whether the land is a protected archaeological monument or the site of an archaeological excavation.
If you are unsure, contact the municipality before searching. Official local rules are available through lokaleregelgeving.overheid.nl.
The six most important metal detecting rules
A municipality may prohibit detecting throughout its territory or in particular areas.
Ask the landowner or another authorised person before you start detecting.
The legal exemption for archaeological detecting applies to ground disturbance up to 30 centimetres.
The exemption does not apply to protected archaeological monuments or ongoing excavations.
Archaeological excavation from underwater sediments is not covered by this exemption.
Report archaeological discoveries and keep them available for scientific research for at least six months.
Is metal detecting legal in the Netherlands?
Yes. Recreational metal detecting is legal in the Netherlands under certain conditions. Since July 2016, a legal exemption from the general archaeological excavation prohibition has applied to qualifying metal detecting activities.
The Dutch Heritage Act (Erfgoedwet) regulates archaeological excavation. Article 2.2 of the Besluit Erfgoedwet archeologie provides an exemption for searching for and excavating archaeological finds with a metal detector, provided the ground is disturbed to a maximum depth of 30 centimetres and all other requirements are met.
This exemption does not grant permission to search everywhere. Protected archaeological monuments, ongoing excavations, underwater sediments and local restrictions can prevent detecting at a particular location.
Current issue: reporting archaeological finds
In February 2026, the Dutch Heritage and Government Information Inspectorate raised concerns about insufficient registration of archaeological discoveries. Correctly reporting finds is therefore particularly important.
How deep are you allowed to dig?
For archaeological excavation with a metal detector, the legal exemption applies to a maximum ground disturbance depth of 30 centimetres.
A signal from a deeper object does not automatically allow you to dig further.
The exemption may apply if all other conditions are satisfied.
Deeper than 30 centimetresArchaeological excavation at this depth falls outside the exemption for amateur detectorists.
Why does this limit exist?
The upper soil layers on farmland are often disturbed by agricultural activities. Deeper layers may contain intact archaeological features such as ancient ditches, postholes and settlement remains.
Disturbing these layers without proper archaeological investigation may destroy valuable historical information.
Practical advice
- Mark the 30 cm limit on your digging tool.
- Use a pinpointer to locate targets accurately.
- Do not continue digging when a target lies below the legal limit.
- Carefully refill every hole.
- Stop and seek specialist advice if you encounter potentially significant archaeological features.
Where can you go metal detecting?
Whether detecting is allowed depends on the location, permission from the relevant landowner or authorised person, archaeological protection and municipal restrictions.
The table below is a practical guide, not blanket permission to search these locations.
| Location | Possibility | Important considerations |
|---|---|---|
| Farmland | Often possible | Ask the owner and, where relevant, tenant. Respect crops and local rules. |
| Pastures | With permission | Take care around livestock, fences and grass. |
| Woodland | Often restricted | Check land manager and municipal restrictions. |
| Nature reserves | Frequently prohibited | Nature protection and management rules may limit detecting or digging. |
| Beaches | Location-dependent | Check municipal, management, dune and water restrictions. |
| Parks | Municipality-dependent | Public access does not automatically mean digging is permitted. |
| Your own garden | Usually possible | Local and archaeological restrictions can still apply. |
| Riverbanks and floodplains | Depends on the site | Check whether the ground is land or underwater sediment and respect environmental restrictions. |
| Underwater sediments | Exemption does not apply | Archaeological excavation from underwater sediments falls outside the exemption. |
Remember: a landowner's permission does not replace legal or municipal requirements.
Where is metal detecting prohibited?
The legal exemption does not apply everywhere. Pay particular attention to:
- Protected archaeological monuments.
- Locations where archaeological excavations are taking place.
- Sites covered by relevant heritage protection procedures.
- Municipalities and locations with metal detecting bans.
- Archaeological excavation from underwater sediments.
- Land where the owner or authorised person refuses permission.
How do you check municipal restrictions?
- Visit lokaleregelgeving.overheid.nl.
- Search for the relevant municipality.
- Find the current APV and search for the Dutch terms “metaaldetector” and “metaaldetectie”.
- Check heritage regulations, the environmental plan and any specific designation decisions.
- Contact the municipality if you are unsure about a particular location.
Do you need a permit for metal detecting?
There is no general nationwide metal detecting permit for ordinary recreational use that falls within the statutory exemption.
However, you must still comply with local restrictions and obtain permission from the owner or authorised person.
Some municipalities may offer exemptions from local detecting bans. The arrangements vary between municipalities.
How do you ask a farmer for permission?
Ask before entering the land. It is sensible to keep agreements in writing, particularly if you intend to return regularly.
Hello, I enjoy metal detecting as a hobby and am interested in finding historical objects. Would you allow me to search your field? I will respect the legal 30-centimetre digging limit, carefully refill all holes, avoid damaging crops and remove any litter. I will report archaeological finds as legally required and check local rules beforehand.
Any agreement concerning finds must comply with the legal reporting requirements.
Do you have to report archaeological finds?
Yes. Archaeological discoveries must be reported under Dutch law. Reporting helps archaeologists understand the history of the Netherlands and protect historically important sites.
Finds can be reported through Portable Antiquities of the Netherlands (PAN) or the Cultural Heritage Agency of the Netherlands (RCE).
Which finds should be reported?
Examples include historical coins, jewellery, buckles, brooches, older everyday objects and other artefacts that provide information about the past.
Modern litter such as drink cans and aluminium foil does not normally constitute an archaeological find. If you are uncertain, contact PAN or an archaeological specialist.
How to report a discovery
- Record the location: Document the findspot as accurately as possible, for example with GPS.
- Take photographs: Photograph the object from different angles, preferably alongside a scale.
- Protect the find: Store objects from different locations separately.
- Report the discovery: Use PAN or the official RCE reporting route.
- Keep it available: Archaeological finds must remain available for possible scientific research for at least six months.
Do not aggressively clean unusual or fragile discoveries. Cleaning may destroy valuable historical details.
Who owns an object found with a metal detector?
Ownership depends on the circumstances and the relevant provisions of the Dutch Civil Code.
Reporting an archaeological find does not automatically mean you must surrender it. Equally, finding an old coin does not automatically make you its legal owner.
Finding a treasure
Where a discovery legally qualifies as treasure, the finder and the owner of the property in which the treasure was found generally become equal co-owners. Whether a discovery meets this legal definition depends on the circumstances.
Recently lost property
Items such as recently lost jewellery or watches may be subject to the legal rules on lost property. The original owner may retain rights. Follow the appropriate municipal reporting procedure.
Important: ownership and archaeological reporting are separate matters. Keep accurate records and seek specialist advice for unusual or valuable discoveries.
What should you do if you find ammunition or an explosive?
Metal detecting in the Netherlands can occasionally uncover ammunition and unexploded ordnance, including objects from the Second World War. These items may remain extremely dangerous after many decades.
- Stop digging immediately.
- Do not touch or move the suspicious object.
- Never take it home.
- Keep your distance and prevent others from approaching.
- In the Netherlands, call 112 and follow the emergency services' instructions.
Never try to determine for yourself whether old ammunition is safe. If you discover possible human remains, stop detecting and contact the police.
