Scout maps the surface, Probe reads the shallow subsurface, Overlord fuses every pass into one interactive 3D volume. This is what lands in your inbox — a meter-scale map of what's under the ground, with every layer traceable to the sensor and physics behind it.
Drag to orbit, scroll to zoom, and toggle each layer — LiDAR surface, mineral bodies in the 0–10 m FDEM detection band, surface metal finds, and the depth-dependent probable-area footprint. The 10–30 m zone is shown as modeled, not detected.

Scout LiDAR builds the surface. The Probe's multi-frequency FDEM coil reads the shallow subsurface — in-phase (I) for magnetic material, quadrature (Q) for conductive metal, and a 16-frequency sweep to place it in depth. The deeper 10–30 m zone in the map is shown as modeled, not detected.
DEM · slope · obstacles · vegetation
Time-of-flight ranging builds a dense 3D point cloud — the base map every subsurface layer registers against.
Steel pipe · rebar · magnetite black sand
High magnetic permeability returns a strong in-phase secondary field. Magnetite is a classic placer-gold indicator.
Copper · aluminum · silver · gold
Eddy-current conductivity drives the quadrature return; the I/Q ratio at each frequency fingerprints which metal it is.
Disseminated ore · brine · alteration
Bulk conductivity contrast vs background; skin depth ∝ 1/√f turns the frequency sweep into 16 depth slices.
Cavities · paleochannels · bedrock
Detected as conductivity boundaries — or the absence of conductivity — against surrounding rock.
Lost jewelry · coin caches · relics
Surface geometry and optical cues plus a shallow eddy-current return recover valuables at or just below grade.
Depths and frequency bands are design targets from the FDEM board spec and the LiDAR platform docs — nominal figures at ~10 mS/m soil conductivity (dry or frozen ground reaches deeper; wet or saline ground shallower). This is the current sensor design scope; hardware integration is in progress.
A small number of free reference surveys in 2026 — landowners, ranchers, exploration juniors. You give us permission and ground truth; we tow the trailer out, fly the survey, and hand you the map.
