Know before you go

Know whose ground you're standing on

Every promising site sits on somebody's ground, and the difference between a good day and a bad one is knowing whose. Detector Maps shows parcel lines with owner details from zoom 14 up, plus Surface Management Agency and protected-area layers, so you know whether the next step is a knock on a door, a walk onto public land, or a hard pass.

Parcel & owner

Know whose door to knock on

Zoom past level 14 and every parcel draws its boundary, with owner details a tap away. Build your permission list from the couch — names, lot lines, and the neighboring parcels, all in one view.

Public or private

See who manages the surface

Surface Management Agency areas color the map by managing agency — BLM, Forest Service, state, and more. One glance separates open public ground from somebody's back forty, before you burn a tank of gas.

Protected areas, drawn before you drive

Military lands, wilderness, national monuments, wildlife refuges, and critical habitat all render as protected areas on the map. Layer in BLM recreation and admin boundaries and the picture of where you can and can't be gets sharp, fast.

Check the line under your boots

Everything on web works on mobile, and it all comes with you offline in the field. Stand at a parcel corner or the edge of a wilderness boundary and see exactly where the line runs.

Put it to work

Four ways detectorists use it

Knock with a name, not a guess

Tap the parcel over that old farmstead and the owner's details are right there on the map. A permission ask that opens with the right name lands a lot better than a cold "do you happen to know who owns this?"

Public or private, right at the fence

Surface Management Agency coloring shows who manages the ground — federal, state, or private — before you step over. When a creek bank or two-track crosses off public land onto a parcel, you see the line on screen instead of hearing about it from an unhappy landowner.

Steer clear of protected ground

Military land, wilderness, national monuments, wildlife refuges, and critical habitat are all layered on the map. These are reference layers for planning — protected sites are off-limits, and knowing exactly where they start keeps your hunt legal.

Plan the route in before you leave

BLM recreation and administrative layers show the access around public ground, so you can pick a legal way in from your desk instead of guessing at the gate. Pair them with the parcel layer to make sure the two-track you're eyeing doesn't cut across private land on the way.

FAQ

The questions we get most

Why can't I see owner names when I zoom out?

Owner and parcel details load from zoom 14 and closer — parcel data is dense, and drawing it at wider views would bury the map. Zoom in on the spot you're researching and the boundaries and owner details appear.

Is this in Explorer or Pro?

Property boundaries and the land-access layers are part of Pro, at $11.99/month or $99.99/year. If you hunt mostly on permissions, the owner details alone tend to justify the step up, and yearly plans come with a 3-day free trial so you can check coverage in your own county first.

How current is the owner data?

Parcel records come from county sources and are refreshed on a rolling basis, but county data always lags real-world sales a little. If a property changed hands recently you might see the previous owner, so treat the name as a strong starting point and confirm at the door.

Can I trust the lines right at the fence?

Boundaries come from county GIS mapping, not a licensed survey, so they can be off by a few yards in places — plenty accurate for research and permission asks, but not for settling exactly where a fence should sit. If you're working tight to a line, give it a respectful buffer or clear it with the neighbor too.
