OKM is a German manufacturer of professional 3D ground scanners and deep-seeking metal detectors, built for treasure hunters, archaeologists, and surveyors who need to locate and image targets far below the reach of a conventional detector. Serious Detecting is an authorized US dealer for the full OKM range — from the eXp and Fusion 3D-imaging scanners to the Rover series, the Gepard ground-penetrating radar, and the GeoSeeker water and cavity detector.

About OKM Ground Scanners
OKM (based in Germany) builds some of the most capable subsurface-detection equipment available to civilians. Rather than swinging a coil for shallow targets, OKM detectors scan a measured grid and render the results as a three-dimensional image — letting you estimate a target's depth, size, and shape before you dig. The lineup spans entry-level scanners through professional multi-sensor systems and true ground-penetrating radar, all aimed at depth and pre-excavation imaging that ordinary metal detectors can't deliver. For deep caches, buried structures, archaeology, and groundwater, OKM is one of the most recognized names in the field.
The OKM Range
OKM organizes its lineup into clear categories, and matching the right one to your goal is the whole game:
3D Ground Scanners — Entry-Level: Fusion Light, Evolution NTX, Rover UC, and Rover C4 — portable 3D imaging scanners that locate and map buried targets to roughly 65–82 feet, ideal for hunters moving into deep-seeking detection.
3D Ground Scanners — Advanced: Fusion Pro, Fusion Pro Plus, eXp 5500 Pro, and the new eXp 7000 Pro Plus — multi-sensor flagship systems that add scan modes, larger sensors, and the deepest, most detailed 3D imaging OKM makes.
Ground Radar: the Gepard GPR 3D uses true ground-penetrating radar to profile large targets and voids at extreme depth.
Water Detectors: the GeoSeeker and GeoSeeker Mini are geoelectric instruments that locate groundwater, cavities, and tunnels by soil resistivity — not metal.
Metal Detectors: OKM also makes conventional detectors — the Pulse Nova and Fortuna Xela — for gold and general detecting. Tell us your target and terrain and we'll point you to the right OKM category.
OKM FAQs
Are OKM detectors any good?
OKM is a long-established German manufacturer and one of the most recognized names in 3D ground scanning and deep-seeking detection. Their systems are built for depth and subsurface imaging well beyond a standard metal detector — the right tool when your targets are deep caches, structures, voids, or water rather than surface coins and relics.
What is the best OKM detector?
It depends on your goal. For top-end 3D imaging, the eXp series is the flagship; for portable 3D scanning, the Rover line; for extreme-depth radar imaging, the Gepard GPR; and for water and cavities, the GeoSeeker. Tell us your application and we'll recommend the right model rather than simply the most expensive.
How deep do OKM ground scanners go?
It varies by model and target size — the Rover scanners reach roughly 65–82 feet on suitable targets, and the Gepard GPR reaches even greater depth on larger objects and voids. Actual reach always depends on target size, ground conditions, and technique.
