Metal Detecting Code of Conduct: The Rules That Keep Sites Open
Quick answer
A detecting code of conduct is a short list of behaviours that keep sites open: get permission in writing, stay off protected land, fill every hole and replace the turf, carry out every piece of metal trash you dig, report qualifying finds under your local scheme, and leave gates and livestock exactly as you found them.
A code of conduct is not a moral lecture. It is the set of habits that decides whether the field you hunted this season is still available next season, and whether the municipality two towns over writes detecting out of its park ordinance. Sites close one at a time, and they close because somebody left a hole, took a call badly, or argued with a warden. Nothing in this hobby is as expensive as losing access to good ground.
The version below is the common core of the codes published by the national associations and by most clubs. It does not replace the law, which varies by country, state, province, county, municipality and parcel, and which is covered in the laws and permission guide. Where the code and the law disagree, the law wins. Where the code is stricter than the law, follow the code anyway, because the code is what the landowner actually judges you on.

What does the code actually say?
Read the right-hand column, because it is the part people skip. Every line of a code of conduct exists because somebody did the opposite and a site closed.
Every published code shares the same six obligations: permission first, protected land never, fill every hole, remove every piece of trash, report qualifying finds, and leave no trace of your visit.
| Obligation | What it means in practice | Why it exists |
|---|---|---|
| Permission first | Written permission for any ground you do not own, naming the parcel and the dates | Trespass complaints are the fastest route to a local detecting ban |
| Protected land never | No national parks, scheduled monuments, protected archaeology or historic battlefields | These carry criminal penalties in most jurisdictions and destroy the hobby reputation |
| Fill every hole | Cut a plug, replace it, tread it down, leave no scar visible from standing height | A single visible hole on a sports field ends detecting there permanently |
| Carry out the trash | Every nail, cap, pull tab and can slaw you dig leaves with you | Livestock injury from dug metal is the reason many farmers refuse detectorists |
| Report qualifying finds | Report under whatever treasure or antiquities scheme applies where you live | Unreported finds lose their context and, in many places, break the law |
| Respect the working land | Gates as you found them, no crops, no livestock disturbance, park where told | Farmers talk to each other, and so do wardens |
| Respect other people | Stay well clear of other detectorists, do not crowd a signal, do not argue in public | A public argument on a beach reaches the parks department faster than anything else |
| Know the ground | Contact the utility location service before disturbing ground on unfamiliar sites | A struck service is a safety incident and a liability claim at the same time |
Wording differs between the national associations and between clubs. The obligations do not.
Why does the trash rule matter more than it sounds?
Because a dug nail left on the surface of a pasture is a foreign body waiting to go into a hoof or a tyre, and a farmer who loses an animal to something you dug up will not ask whether you meant it. This is the rule that decides whether a working farm ever lets a detectorist back. Carry a second compartment for trash and empty it into a bin at the end of the day, not into the hedge.
It is also the rule that quietly improves your hunting. A site you have cleared of shallow iron and aluminium is a site where the next pass hears the deeper targets that were masked before, which is the same effect a small coil buys you and is discussed in the coil size chart. A pouch such as the CKG Finds and Digger Pouch has a separate compartment for exactly this, and the Garrett All Terrain Dig Pouch is the larger version for a full day on trashy ground. Serious Detecting Gloves (large) are what make handling rusted metal and buried glass sensible.
How should you behave when somebody challenges you?
Stop swinging. Put the machine down. Produce your permission if you have one, and if you are on public ground, produce the rule you are relying on. Answer questions plainly, do not argue about jurisdiction with somebody who is not going to be persuaded, and leave if you are asked to leave even when you believe you are entitled to stay. You can sort out a misunderstanding later by telephone with the parks office. You cannot undo a scene witnessed by twenty people in a public park.
Carry the things that make you look like what you are: a tidy pouch, a proper digger, gloves, and a machine that is not screaming at full volume. Wireless headphones such as the Minelab ML105 Wireless Headphones for Minelab machines or the Garrett MS-3 Z-Lynk Wireless Headphones for Garrett ones keep your audio to yourself, which matters more in a busy park than most people realise. The signal guide covers why you probably want headphones anyway.
What about finds, and what about telling people where you found them?
Report what your local scheme requires you to report, and do it within whatever period it specifies. Beyond the legal duty, the working convention is that you tell the landowner what came off their land, that you agree a split in advance rather than afterwards, and that you do not publish precise locations of productive historic sites. That last convention exists because published locations attract people who do not ask permission, which is how sites get stripped and how landowners stop saying yes.
Photograph a find in the ground before you lift it if it looks significant, note the depth, and then stop. Context is most of the information an old object carries, and it is destroyed the moment the object moves. The same instinct applies to cleaning, which is why the cleaning guide opens by telling you not to.
Does joining a club actually help?
More than most newcomers expect. Clubs carry public liability insurance, which almost no individual detectorist arranges and which is increasingly what a landowner or a parks department asks for before saying yes. They hold a current picture of which local authorities permit detecting, which is the information that dates fastest. They run organised permissions on land that no individual would get access to. And they will look at your finds, which is worth a great deal when you are trying to work out whether something is a button or a coin.
The trade is that a club expects the code to be followed exactly, and will say so. That is the point. If you are still assembling gear before your first outing, the beginner setup lists a complete kit, and the beginner guide covers the first season in order.

Frequently asked questions
Is a code of conduct legally binding?
Not in itself, but large parts of it restate duties that are legally binding, including permission, protected land and reporting. The rest is the standard a landowner, warden or club will actually judge you by. Breaking the code will not usually put you in court, but it will lose you the permission, and in a club it will lose you the membership. Follow the law first and the code on top of it.
Do I really have to carry out every piece of trash?
Yes, especially on farmland. Dug metal left on the surface can injure livestock and damage machinery, and a farmer who loses an animal will never allow another detectorist on the land. It also improves your own hunting, because clearing shallow iron and aluminium unmasks the deeper targets underneath. Use a pouch with a separate trash compartment and empty it into a bin, not a hedge.
What should I do if I find human remains?
Stop immediately, do not disturb anything further, and contact the police. If the remains appear to be archaeological rather than recent, the police will involve the heritage authority, but that judgement is not yours to make in the field. Do not photograph and publish, do not continue detecting in that area, and do not remove anything. This is covered further in the safety and utilities guide on this site.
Can I detect somewhere that looks abandoned?
No. Abandoned looking land still has an owner, and derelict buildings and overgrown lots are among the easiest ways to end up trespassing while also standing on broken glass and unstable ground. Find the owner through the land record and ask. An abandoned appearance sometimes also means a site that has a heritage designation nobody maintains, which makes it worse rather than better.
Should I tell people where I found something good?
Tell the landowner, and report the find if your scheme requires it. Beyond that, the convention is to keep precise locations of productive historic sites private. Published locations attract people who do not ask permission, sites get stripped, and landowners stop granting access to anybody. Share the find and the story, keep the grid reference between you, the owner and the recording scheme.
