Understand your permission before you arrive.

A slope. An old route. A water source. A pattern of finds. Our engines bring those clues and more together, using archaeological methods to help you interpret your permission and decide what deserves a closer look.

  • Shows its workingSee what supports an interpretation, what weighs against it and how confident it is.
  • Clues considered togetherMultiple landscape and historic signals are considered together to help focus investigation.
  • Protected landscape awarenessScheduled monument boundaries are visible before you are standing on them.

FieldGuide highlights potential and helps focus your search. It does not guarantee finds.

Every permission has a story.

A plain field becomes more useful when landscape evidence and your own records are viewed together.

Read the shape of the land

Terrain and water context help explain how people may have moved through and used a landscape.

Put clues in context

Historic routes, mapping and recorded archaeology give individual signals a wider setting. See what supports an interpretation and where information is limited.

Build on your own visits

Recorded finds, observations and trails add local context for your next visit. A recorded trail shows where you travelled; it does not prove the ground was fully searched.

Suggestions guide investigation; they are not a probability of finding an object. Missing evidence remains a limitation, not proof that nothing is there.

Your own recorded finds become evidence in FieldGuide.

Use FindSpot, record what happened, build local context and return with better information. Your private find records stay on your device unless you choose to export or share them.

FindSpot supports responsible handling when a discovery needs more than a normal find record.

Protect what may remain

Record the position and preserve context before further disturbance.

Map Scatter

Preserve the pattern

Log separate points before the relationship between them is lost.

Notable Find

Capture what matters

Keep photos, location, context and follow-up details together.

Supports responsible recording. Does not constitute legal or reporting advice.

Common questions

Does it work on iPhone and Android?

Yes. FindSpot is a Progressive Web App, so it works in a modern phone browser. On iPhone, open it in Safari and use Add to Home Screen. On Android, your browser will usually offer to install it.

Do I need to create an account?

No. There is no account, login or email required. You can start using FindSpot immediately.

Does it use mobile data in the field?

Find recording and permission management work offline. Load your maps and FieldGuide information while connected, then check what is available before heading out. New landscape data needs a connection. Browser and phone settings can interrupt GPS trail recording, especially when the screen is locked.

What if I lose or replace my phone?

FindSpot supports explicit, user-controlled backups and reminds you when changing records need protection. Save the backup somewhere safe, then use FindSpot's validated restore tools on your replacement device. Recovery is not automatic cloud sync.

Is it really free?

Yes. FindSpot is free to use in full, with no adverts, subscription, locked tier or account requirement.

What is FieldGuide?

FieldGuide analyses terrain, water features, historic routes and recorded archaeology — including Portable Antiquities Scheme data and your own locally recorded finds — and shows the evidence behind its interpretations. It helps focus a search, but it does not guarantee finds.

What if I find something important?

FindSpot includes guided workflows for Stop & Secure, Map Scatter and Notable Find records. They help preserve context and support responsible recording, but they do not replace professional or legal advice.

Don't just detect the land. Understand it.
