Built for the hobby

Everything detectorists actually want.
All in one app.

Searchable library

Every find. Searchable forever.

Photo, location, category, notes — plus an AI identification when you snap something and aren't sure what you pulled. You get a best-guess ID, era, and confidence so you don't have to dig through forums to find out what's in your hand. All of it kept in one place that survives phone upgrades, app updates, and the years between digs. Filter by category, spot, or date — find the silver dime you dug three summers ago in two taps.

Hunts + Map

Every dig, tracked and mapped.

Start a hunt when you walk into the field — every find you log auto-attaches with a GPS pin. End the hunt to see duration, steps taken, and distance walked, measured by your iPhone at zero battery cost. Pro members get route maps: your GPS trail drawn over satellite, private to you, so you know exactly what ground you've covered — and what you haven't.

LiDAR terrain — Pro

See what the trees are hiding.

Dtecto Pro overlays USGS LiDAR directly on your hunt map — hillshade, slope, and elevation-tint modes that strip away vegetation and reveal what's really on the ground: old foundations, mounds, earthworks, forgotten roads. The research tool serious detectorists use, in your pocket, standing in the field.

Historical overlays — Pro

Every old site, on one map.

Layer the map with the places worth detecting. Public lands color-coded by managing agency, with detecting rules a tap away. Rivers, streams, and lakes. Historic places from the National Register and OpenStreetMap, with photos and Wikipedia summaries. Civil War, Revolutionary War, and 1812 battlefield boundaries. USGS abandoned mines across the West and Midwest. Density bubbles show the productive country from any zoom, and map search flies you to any address or coordinates.

Community feed

Detectorists who get it.

Post your finds, follow other detectorists, give a coil bump on a recovery that hits. Every find has its own visibility toggle — private finds never appear in the feed or on the community map, and you control whether a public find shares its location. Real people, real digs, no algorithm.

And the rest

Every feature a serious detectorist needs.

28 brass achievements

Medallions across find counts, hunt counts, categories, and monthly streaks. Auto-unlock the moment you qualify. Aspirational ones stay visible so you know what's next.

Saved spots

Long-press the map to drop a pin on a permission, a hot field, or a spot you want to come back to. Orange star pins, separate from your find pins.

Private by default

Every find has its own visibility toggle. Private stays private — not on the map, not in the feed, never shared. You control whether a public find shares its location.

Layers for days

Map or satellite base, plus stackable overlays. Public lands, waterways, and map search are free; LiDAR and the historical overlays are Pro.

Achievements

Earn brass for every milestone.

28 hand-designed medallions across find counts, hunt counts, categories, and monthly streaks. Earn them by playing — they unlock automatically the moment you qualify.
