You came home with a pouch of green coins and a muddy boot. Where was the Roman one? Which field gave you the hammered silver last spring? This is the notebook that remembers for you.
Start with the board of sites you have permission for: field, beach, woodland. Note the landowner, the date permission was given, when it ends and keep a photo of the signed note. Every hunt and every find hangs off a site, so nothing floats around loose.
Log a hunt in a few taps: the detector, programme and sensitivity you ran, the coil, hours on the ground. Log a find with a photo, depth, target ID, category (coin, relic, jewellery, trash), era, weight and a GPS fix that keeps the accuracy your phone reported. Open any find or site in your own maps app with one tap.
Pro adds the numbers detectorists argue about in the club car park: finds per hour, best sites, best settings, plus permission expiry reminders. Export your finds as CSV, or build a tidy list with photos to take to your Finds Liaison Officer for a Portable Antiquities Scheme report (a working list, not an official form). Back up everything to a file, restore it on a new phone.
Free plan: 2 sites and 50 finds. Pro: unlimited sites and finds, stats, permissions vault, CSV and FLO export. Yearly plan starts with a 7-day free trial; lifetime is a one-time payment. This app does not map protected or scheduled sites and does not encourage detecting without permission. Always detect with the landowner's permission and follow local law.
Sites, permissions, hunts and finds in one log. See which spots really pay off.
