How to use
Fieldcraft Heritage

Help, Day mode and the bottom bar

1. Tap the gold ? ball at the top right of any screen for help with that screen. Pop-up forms have their own small gold ?.
2. Tap ☀️ Day to switch to a high-contrast look for bright sunshine. Tap it again to switch back.
3. Use the bottom bar to move around: Home, Session, Finds, Intel, Settings and Gallery. Session only works while a dig is running.

What needs signal

1. Logging finds, hazards, marks, notes and your walk works with no signal at all.
2. Maps, weather, place search, the welcome pictures and the Field Memory write-up after five sessions need signal or wi-fi.

Before heading somewhere with poor signal, tap Cache Map on the Home screen while you still have signal.

Edit, delete or switch permission

1. Go to Settings, find the permission under Permissions and tap Edit or Delete.
2. With two or more permissions, the Home screen shows a row of permission names. Tap a name to switch to it, ✎ to edit it or ✕ to delete it.

Deleting a permission doesn't delete the finds and sessions you recorded there.

Log your detector settings

1. When you start a session you're asked for your settings. Fill in what you use, then tap ▶ Start Session, or tap Skip — start without settings.
2. Changed something on the detector mid-dig? Tap ⚙ Log Settings on the session screen, update it and save. Every find after that is tagged with the new settings.
3. For discrimination, open ⊞ Discrimination Grid and tap squares: gold means accept, dark means reject.

Intel → Kit compares your keepers against the frequency and sensitivity you used, so it's worth filling those in. A change logged mid-session counts from the moment you log it.

Pre-Trip Plan

1. On the Home permission card tap Pre-Trip Plan. During a dig, tap 📋 View Plan to open it.
2. Switch the map with SAT, STREET, OS (Ordnance Survey 1888) and LIDAR (Environment Agency hillshade, England only). Bumps, banks and old ditches show up well on LIDAR.
3. Your previous walks are drawn in colour, with the newest in yellow.
4. To mark spots to try: tap 📍 Drop Pin, type a note in Pin note… first if you want one, then tap the map. Drag a pin to move it, or tap it and choose ✕ Delete. Tap ✕ Stop when you're done.
5. Under 🗺 Historic Maps, open older maps for this exact spot, including the OS Old Series from 1798.
6. Type anything you want to remember under Planning Notes and tap Save Plan.
7. Tap Close when finished.

Deleting a pin doesn't ask you to confirm.

Save the map for offline use

1. While you still have signal, tap Cache Map on the Home permission card.
2. Wait for Map cached — ready offline.

Quick Dig: club digs and one-off sites

1. On Home tap → Quick Dig or or Attending a Dig →.
2. Type a Dig Name.
3. Optionally set a Location with Search or 📍 Use Current GPS Location, and drop planning pins.
4. Tap → Start Session.

A Quick Dig isn't saved as a permission, but every find is kept in your Finds.

Before you dig card

1. At the top of the session, tap the ground you're on today: Ploughed, Cultivated / drilled, Stubble or Grass / pasture.
2. Tap 📷 Field photo to take a GPS-stamped picture of the field.
3. Tap Done ✓, or Later to hide the card.

Recording the ground each time is how Field Memory learns which ground is best.

Log a find

1. Tap the big Log Find button the moment you dig something.
2. Wait for GPS Locked. If it says GPS unavailable, step into open ground and tap ↺ Retry GPS.
3. Optionally enter the signal: the VDI number, plus Stability and Tone.
4. Tap Photograph Your Find. Add more photos with Back / more or Library (up to six).
5. Enter the Depth (cm) and choose Coin, Relic or Unknown.
6. Add notes, or tap 🎤 Dictate and speak.
7. If it's a good find, tap ☆ Mark as Keeper. If it's rubbish, tap Mark as Scrap.
8. Tap 📍 Save Find.

📍 Save Find only works once GPS has locked and a type is chosen.

Material, period, weight and size are added later in Enrich (see Your finds).

Typing the VDI lets the app tell you what that number has turned out to be on this ground before.

Only finds you star as ⭐ Keepers count as good finds in your rates and in Intel. You can star them later too: tap ☆ on a find in Finds → All finds. Scrap is left out of your finds rates. If most finds in a spot are scrap, the app says so and marks it as a 🗑 junk patch on your maps.

Flag a hazard

1. Tap ⚠ Hazard.
2. Pick the type, for example Ditch, Elec. Fence or Bull.
3. Drag the pin or tap the map to put it in the right place.
4. Add notes or a 🎙 Voice Note if useful, then tap ⚠ Save Hazard.

Hazards stay on this permission's maps for every future visit.

Mark a spot (including Come Back)

1. Tap ⭐ Mark.
2. Pick a type: Promising, Iron Patch, Boundary, Hot Spot, Come Back, Water or Note.
3. Place the pin, add a note and tap ⭐ Save Marker.

Come Back spots show as blue ↺ pins on later visits. Tap one and choose ✓ Dug — found something to log a find right there, or ✓ Dug — nothing there to clear it.

Field notes

1. Tap 📋 Notes.
2. Type how the detector and ground are behaving, or tap 🎙 Dictate to record your voice. Tap it again to stop.
3. Tap Save Field Note.

In Field Notes, 🎙 Dictate saves a voice recording. It doesn't turn speech into text.

Using the session map

1. 📍 Centre jumps the map to where you are.
2. 🥾 Trail On/Off shows or hides the line of today's walk.
3. ⛶ makes the map full screen.
4. SAT, STREET, OS and LIDAR change the map, the same as in Pre-Trip.
5. Tap a find pin to see it, then tap its photo to view it full screen. Hazard and mark pins can be dragged to correct them.
6. 📍 Re-ping GPS gets a fresh position fix if your position dot looks wrong.

Pocket mode: accurate walk tracking

1. Tap 🌙 Pocket before putting the phone in your pocket.
2. The screen goes black, ignores taps and keeps recording your walk.
3. To get back, swipe up firmly on the screen.

If the screen switches itself off, many phones stop sending GPS and your walk line gets gaps. Pocket mode keeps the screen awake but black, so the line stays accurate.

End the session

1. Tap End, then End Session. Tap Keep Detecting if you change your mind.
2. The Session Complete screen opens (see After the dig).

Everything is saved as you go, so ending never loses anything.

Report to your FLO

1. On Session Complete tap ✉ Contact FLO.
2. Tick the finds to report, then tap Continue.
3. Choose your county under Select Your FLO, or type their email.
4. Check Your Name is correct.
5. Tap ⤴ Share with photos to send through your email app with photos attached, or Open in Mail App → for text only.

FLO reports include the permission name and each find's position, because the FLO needs them to record the find properly.

Share with your dig leader

1. On Session Complete tap ✉ Share with Dig Leader.
2. Untick anything you don't want to include.
3. Enter the dig leader's email and your name.
4. Tap ⤴ Share with photos or Open in Mail App →.

This report has no location and no permission name.

4. Tap ⤴ Share and pick the app to post with.

No farm name, location, map links or notes are included, and the GPS data is removed from the photos.

2. Add field photos and Cleaned photos (front, back, side…) with 📷 Another or 🖼 Library, up to six of each.
3. Fill in Name / Description, Material, Period, Weight (g), Length / Ø (mm) and Width (mm).
4. Tap Save Record.

Tapping outside the form closes it without saving, so always tap Save Record.

A cleaned photo makes a big difference to an FLO.

Zoom, scale and measure photos

1. Tap any photo to open it full screen.
2. Pinch, double-tap or use － ＋ to zoom, and drag to look around. Swipe to the next photo.
3. To add a size scale (from Enrich Find): tap 📏 Scale, tap both edges of a coin in the photo, then pick that coin (1p, 2p, 5p, 10p, 20p, 50p, £1 or £2).
4. With a scale set, tap 📐 Measure, tap both ends of the find, then tap Set as length or Set as width.

2. Pick the permission, then tap the map where it was found.
3. Fill in What is it? and Year found, plus anything else you know.
4. Tap Save past find, or Save & add another.

Past finds show on your maps but don't count towards session statistics.

What each tab shows

1. Summary: your keepers against scrap and finds not yet starred, what's working, what to watch out for (including trashy ground) and your personal bests.
2. Places: finds per hour and per km, every session as keepers, not starred and scrap, your fields, the Finds map and Hazards and marks.
3. Conditions: what each permission has taught the app about ground and weather, and how often its calls were right.
4. Kit: coils, frequencies and sensitivity compared, as keepers an hour and time used. Tag the coil on each session in Finds → Sessions; frequency and sensitivity come from the settings you set at the start of a session or with ⚙ Log Settings.
5. Finds: good finds by material and by depth, and your highlights. Any good find without a material is listed under By material: pick it there and the page updates.

Most comparisons need at least two finished sessions. The more you log, the better it gets.

Draw your fields

1. In Intel, open Places and tap ✏️ Draw your fields on the Fields card.
2. Tap ＋ Draw a field, then tap round the edge of the field. Your old walks show faintly to help.

Importing a plan never touches your finds, sessions or walks.
