Detector Maps is the field tool that keeps you on the gold - and on the relics. Built by geologists for prospectors, relic hunters and metal detectorists across the United States, Australia, New Zealand and Canada, it pairs geological data and historical maps with rock-solid GPS so you spend your time on high-potential ground, not guessing. Whether you are swinging a detector for gold nuggets, coin shooting an old homestead, hunting Civil War relics or panning a creek, it puts serious research intelligence in your pocket - and it works offline, where the finds actually are. COIN & RELIC HUNTING - NATIONWIDE Research old towns, ghost towns, homesteads, schoolhouses and long-forgotten gathering places - the ground where old coins, buttons, buckles and relics are still waiting. - Historical map overlays: hunt the buildings, roads and fields the modern map forgot - Historic USGS Topo maps, coast to coast - LiDAR that reveals cellar holes, old roads and house sites hiding under the trees - Plan permissions with confidence before you knock GOLD PROSPECTING - 15 STATES Serious geology for nugget hunting, from California to the Carolinas. Detect where gold has already been found, then find what the old-timers missed. - Historic gold mines, diggings and workings - proven gold ground - Surface geochemistry with pathfinder-element filtering - Current and expired mining claims, updated every weekday - 1-metre LiDAR hillshade that reveals old workings worth a closer swing DETECTOR ACADEMY A built-in crash course: 34 short video lessons, most under a minute - layers, LiDAR, waypoints, trails, offline maps and Pro tools. DETECTOR GRIDS Plan complete, methodical coverage of a site with adjustable search lanes you follow while recording your trail - never grid the same ground twice. BREADCRUMB TRAIL TRACKING (BACKGROUND GPS) Record your exact trail even with the app in the background or the screen off. See where you have walked and save paths for the next trip. WHY WE REQUEST "ALLOW ALL THE TIME" LOCATION ACCESS Detector Maps only uses background location when you switch breadcrumb tracking ON, keeping an unbroken log while your phone is idle. Disable it anytime in the app or device settings. WAYPOINT MARKING AND FIND LOGGING Drop waypoints on coins, relics, gold finds and old workings. Add names, notes and photos, then sync securely between your phone and the web app so your finds are never lost. REAL-TIME GPS NAVIGATION Watch boundaries, geology, historical maps and terrain update around you as you move - a GPS built for prospecting, coin shooting and relic hunting.

Verdict
The clearest difference is monetization model: Spartan Forge at free with in-app purchases against Detector Maps's subscription. Spartan Forge also leads on ads (none vs shown) and review sentiment (82% vs 73%). Detector Maps's advantage is update cadence (every 6 days vs every 5 weeks) and rating (4.6 vs 4.3). On price, ratings volume, in-app purchases and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Spartan Forge sells 7 in-app purchases, starting at $7.99 per month and Detector Maps sells 4 in-app purchases, starting at $7.99 per month. Whichever you choose, the download price is not the number that matters.
Detector Maps holds the better App Store score, 4.6 against 4.3. Both are backed by a comparable volume of ratings — 644 and 265 respectively. Written reviews complicate that: 82% of Spartan Forge's written reviews are positive against 73% of Detector Maps's, so the app with the better star average is not the one people write more warmly about.
Spartan Forge ships an update every 5 weeks, Detector Maps every 6 days. Both last shipped on October 30, 2026.
