485 NEW HISTORIC PLAT MAPS JUST ADDED TO SUBTERRIX

We just expanded our historic plat map collection from 879 to 1,364 maps - a 55% increase.

Coverage also grew from 25 to 31 states, with plat maps now available for the first time in:

Florida • Minnesota • Texas • Maryland • Michigan • North Carolina
And these aren’t just scanned historic maps.

They’ve been georeferenced so they align directly over the modern map — giving you a precise historical overlay of old roads, property lines, structures, landowners and features against today’s landscape.

The biggest expansion came in Massachusetts, where coverage jumped from 39 to 501 maps, including hundreds of historic town and city atlases from the Boston Public Library.

We also added new material for Wisconsin, Pennsylvania, Ohio, Illinois, Indiana, New York, Virginia, Washington and more.

Every map in this release came from trusted public collections, including the Boston Public Library, Library of Congress, University of Minnesota, Cleveland Public Library and Northfield Historical Society.

485 new maps. 31 states. Perfectly aligned historic intelligence, directly over today’s terrain.

We're just getting warmed up. Tens of thousands more in the works.

Did you know that metal detecting clubs can earn money from Subterrix? We already have hundreds of clubs making money.

The Subterrix Clubs Program is designed to help metal detecting clubs give their members access to powerful modern research tools at an affordable price.

Members benefit when their metal detecting club join. Instead of paying 19.99 per month for 300 credits, they pay $8.99 per month for 300 credits. The club does not pay anything to join Subterrix. And they earn 20% of every Elite Membership per club member. The club organizer (the person who signs up the club) gets 100 free credits per month. Subterrix combines historical research, mapping, terrain analysis, LiDAR, site intelligence, and millions of historical data points to help detectorists locate promising places to hunt and better understand the ground beneath their feet.

Clubs can bring these tools directly to their members while becoming part of a growing community focused on research, education, and responsible metal detecting.

Joining the Subterrix Clubs Program is free for the club, and participating clubs can unlock special discounted Subterrix Elite pricing for their members. Whether your club has ten members or hundreds, the program is an easy way to add value to membership, introduce detectorists to advanced research technology, and help members spend less time guessing and more time finding productive sites.

Visit Subterrix.com/clubs to learn more and get your club involved.

COMING 10/15: OMNIMAP - THE NEXUS INTERFACE

For current users, OmniMap means less jumping between tools and more doing: pick a place once, then research, analyze, plan and hunt from one connected experience.

One place. One interface. The power of Subterrix brought together.

OmniMap is not another tool.
It’s the new way Subterrix works.

Launching October 15.

5,000.

Yesterday, Subterrix crossed 5,000 registered members. Here's what that climb looked like:

December 2025: 2
January 2026: 22
February: 77
March: 180
April: 248
May: 1,041
June: 1,759
July: 2,756
August: 3,865
September: 5,122

It took us five months to reach our first 248 members. It took five more to add nearly 4,900. September was our biggest month ever, with 1,257 new members, and as of this morning we're at 5,124.

From two accounts to more than five thousand in about nine months. As far as we know, no research platform in metal detecting has grown this fast.

None of this happened through ads. It happened because detectorists told other detectorists. Every share, every referral, every "you have to see this" at a club meeting or in a comment thread built this. Our ambassadors, our BaseCamp veterans, our Elite members, Founders, and everyone who signed up just to see what we were about: thank you.

We built Subterrix on a simple idea: research responsibly, detect with purpose, and with the right preparation, luck becomes optional. Five thousand of you are proving it.

On to 10,000.

🗺️ IT'S LIVE. HISTORIC PLAT MAPS ARE NOW IN SUBTERRIX EXPLORER. 🗺️

Every detectorist knows the feeling. You're standing in a field wondering who lived here. Where the farmhouse stood. Where the old road ran before it vanished. Where the schoolhouse, the mill, the blacksmith shop used to be.

Now you don't have to wonder. Now you can SEE it.

Open Explorer. Flip on Historic Plat Maps. And watch the 1800s slide right over today's map, lined up with the ground you're standing on.

🏚️ Old homesteads and farmhouses that are long gone
📜 Landowner names written right on their parcels
🛤️ Roads that don't exist anymore
🏫 Schoolhouses, churches, mills, blacksmith shops, taverns
🎚️ Fade the old map in and out to see exactly where then meets now

We're launching with nearly 2,600 historic maps, including almost 900 hand-drawn county and town plat pages from the 1860s, 1870s and beyond, with deep coverage across New York, New England, Ohio, Pennsylvania, California and more.

A quick word on numbers, because this hobby deserves straight talk.

Anyone (Yes, I'm calling them out) can inflate a map count by throwing in world maps, ocean charts and maps of places you'll never set foot. We didn't.

Every map in Explorer covers U.S. ground, every one was published in 1929 or earlier, and we sorted them honestly: 879 true plat and town pages you can actually use in the field, plus 1,700+ more historic maps, from old town and harbor maps to colonial-era regional maps for the bigger picture. No padding. No fluff. Just maps that matter when you're standing on the ground.

AND WE DIDN'T STOP THERE.

🕰️ Historic Regional Maps is a second new layer with a time slider that takes you decade by decade from the 1670s to the 1920s. Watch colonial trails, early settlements, forts and frontier roads appear and disappear across the land, century by century.

These maps come from the legendary David Rumsey Map Collection at Stanford University, one of the greatest historic map archives on Earth, now working for you, right inside Explorer.

This is how a hunch becomes a plan. This is how you knock on a landowner's door already knowing the history of their land. This is the research edge no one else in this hobby is giving you.

And we're just getting started. More maps are already on the way. 🔥

👉 Log in to Subterrix, open Explorer, and hit Map Layers → Historic Plat Maps.

Go find where history happened. Then go dig it up. 🪙
