How to Get Metal Detecting Permission: Asking Owners and Keeping Access
Quick answer
Find the legal owner through the land record rather than by assumption, approach them in person in daylight, ask for a specific piece of ground for a specific period, and put the agreement in writing with the finds split and the reporting duty spelled out. Expect most answers to be no, and keep the ones that say yes.
Permission is the actual bottleneck in this hobby. Machines are easy to buy and ground is not, and the difference between somebody who finds interesting things and somebody who grinds the same municipal park for a decade is almost always access rather than equipment. The good news is that asking is a learnable skill with a fairly predictable hit rate, and the people who are good at it are not charming, they are organised.
Everything on this page assumes you will operate inside the rules covered in the laws and permission guide. Getting permission from an owner does not override a heritage designation, a park ordinance or a reporting duty, and no amount of goodwill from a farmer makes a protected site available. Check the designation before you knock, not after.

How do you find out who owns a piece of ground?
Through the record, not through the village. County recorder and assessor databases in the United States, the land registry in the United Kingdom and equivalent registries elsewhere will give you an owner name for a parcel, usually online and usually free to search. Do that before you ask anybody anything, because the person you see on the tractor is frequently a tenant, a contractor or a neighbour, and a permission from the wrong person is worse than none: it feels like permission and is not.
On let land you may need both the owner and the occupier. The owner controls what is in the ground and the tenant controls what happens on the surface this season, including whether you can walk across a standing crop. Ask each of them the parts that are theirs to answer, and say clearly to both that you have spoken to the other.
What actually works when you ask?
The pattern below is what experienced club members consistently describe. The right-hand column is the reason, and the reasons matter more than the script.
Asking in person in daylight for one specific field, with written permission and an offer to share finds, converts far better than a letter, a phone call or a general request to search a whole holding.
| Approach | Typical result | Why |
|---|---|---|
| Knocking in person, daylight, tidy, no machine in hand | The best hit rate available | The owner is deciding whether to trust a person, not a hobby |
| A posted letter with a return contact | Low response, but occasionally opens large holdings | Easy to ignore, but it reaches owners who live elsewhere |
| A telephone call out of the blue | Usually a no | Nothing about a voice on the phone reduces the owner risk |
| Asking for one named field | Much better than asking for everything | A small yes is a small decision, and it can grow later |
| Asking to search the whole farm | Usually a no | It sounds like an open-ended commitment to a stranger |
| Offering written permission yourself | Improves the yes rate noticeably | It signals that you have done this before and take it seriously |
| Offering to show every find | Strongly positive | Owners are curious about their own land, and this is the part they enjoy |
| Turning up during harvest or lambing | A no, and a remembered one | Timing is most of courtesy on a working farm |
These are the patterns members of established clubs consistently report. They are not survey data and your local picture will differ.
What should the written agreement contain?
- The parcel, named precisely. Field name, lot number or address, with a sketch for a large holding. Ambiguity here is what causes disputes later.
- The people. Your name and contact details, the owner name, and the occupier name if the land is let.
- The period. A start and an end date. A season that both sides can renew is easier to agree than an open-ended arrangement.
- The finds split. Whatever you agree, written down before anything is found. Fifty fifty is common, and the number matters less than the fact it is settled.
- The reporting duty. A line saying that qualifying finds will be reported under the scheme that applies, and that the owner will be told about anything significant.
- The practical terms. Parking, gates, livestock, crops, hours, and your undertaking to fill every hole and remove all dug metal.
- Two signatures and two copies. One for each of you. Carry yours, digitally or on paper, whenever you are on the land.
How do you keep a permission once you have it?
By being the least trouble the owner has all year. Text before you come rather than appearing. Park where you were told. Leave gates as you found them. Fill every hole properly, which is a specific skill covered in its own guide, and carry out every piece of dug metal because a nail in a pasture is a vet bill waiting to happen. Show the owner what you found, even when it is a handful of buttons and a modern coin, because that is the part they were actually curious about.
Two more things buy a surprising amount of goodwill. The first is finding things the owner has lost: a ring, a hitch pin, a dropped key in a paddock. The second is turning up with a machine that behaves in their soil rather than falsing constantly, which is a ground balance question covered in the ground balance guide. A detectorist who spends an hour recovering a lost wedding ring from a lawn is welcome on that land for years.
How many permissions do you actually need?
Fewer than you think, if they are good ones. A single old pasture that has never been detected will out-produce a dozen hunted-out parks, and it will keep producing for years because you cannot clear a field of targets in one season. The realistic aim for the first year is two or three pieces of ground you can get to easily, rather than a list of twenty you will never visit twice.
Work out how long a site actually takes before you promise an owner anything. The coil coverage and sweep time calculator converts coil width and sweep speed into hours per acre, and the numbers surprise most people the first time they see them. The search grid planner then turns the field into lanes so it gets covered once properly rather than three times badly.

Frequently asked questions
How do I find the owner of a field?
Search the public land record rather than asking around. County recorder and assessor databases in the United States and the land registry in the United Kingdom will return an owner for a parcel, usually online. This matters because the person working the land is often a tenant or a contractor, and permission from somebody who does not own the ground is not permission at all, however genuinely it was offered.
Should I offer the landowner a share of what I find?
Offer, and settle the split in writing before you start. An even split is the common convention and the exact figure matters far less than agreeing it in advance. Also make clear in the same document that qualifying finds will be reported under whatever scheme applies where you are, because that duty is separate from any private agreement and does not go away because you shook hands.
How many people say yes?
Most say no, and that is normal rather than a reflection on you. Experienced club members generally describe knocking on many doors for each permission granted, with the rate improving sharply once you have a reference from a neighbouring owner. Ask for one specific field rather than a whole holding, bring a written permission form with you, and keep a record of who you have already asked.
Do I need insurance to detect on somebody else land?
You are rarely required to hold it as an individual, but more landowners and parks departments now ask for public liability cover before they agree. The usual route is club membership, which normally includes it, and which also gives you access to organised permissions on land no individual would get. Ask the owner directly whether they want to see cover, because some will.
Can I detect on a friend property without anything in writing?
You can, and it still pays to write two lines down. A short note naming the parcel, the dates and what happens to finds prevents the awkward conversation when something valuable appears, and it protects the friendship more than it protects you. It also gives you something to show if a neighbour or a warden asks what you are doing on that ground.
