OKM Rover UC and Rover C4: Your Advance into the Unknown
Your treasure hunt demands more. OKM’s best-selling 3D ground scanner series, built for the toughest demands in the field.
OKM Rover: 3D Ground Scanners for Explorers Who Want More
A hunch becomes a point on the map; a carefully planned search becomes a real mission. That is exactly what the OKM Rover series is built for: two models, ready for your next expedition.
Every search with an OKM Rover is built on 3D Ground Scan technology: depending on the model, treasures, artifacts and cavities can be located at depths of up to 25 metres and displayed as a colour-coded 3D visualisation.
The OKM Rover series extends this foundation with two powerful features that push the limits of what is possible in treasure hunting even further:
- Rover C4 – Mineral Scan: A dedicated operating mode for natural gold prospecting: it tracks down subsurface mineralisation that points to natural gold deposits.
- Rover UC – Discreet search: Disguised as a trekking pole and controlled by smartwatch: a search that draws no attention.
Everything a 3D ground scanner can do. And more.

Let’s talk about it.

3D ground scanner and gold detector
OKM Rover C4: The All-Rounder
Treasure, bunker or natural gold: with magnetic field sensors and four operating modes, the Rover C4 is equipped for every one of these trails.
OKM Rover C4
Gold Detector and Absolute Favorite for Treasure Hunting
Sound and light show the way
The LED orbit makes locating targets easier: the acoustic signal and the coloured light display immediately indicate where there is an anomaly in the magnetic field. A detected object is pinpointed in no time.

Two probes for a clear picture
The lightweight 0.4-kilogram standard probe handles the 3D Ground Scan of the survey area. The additional super probe enables more precise location through higher-resolution 3D scans – it is also the probe used to run the Rover C4 in Mineral Scan and Pinpointer mode.

Gold prospecting with the Rover C4
Fitted with the super probe, the Rover C4 becomes a gold prospecting tool. Mineral Scan detects mineralisation typical of natural gold deposits in quartz veins and bedrock. The OKM white paper on gold prospecting shows what the characteristic signal patterns look like.
Covert 3D ground scanner
OKM Rover UC: The Discreet One
Not every search welcomes an audience. Some places can only be explored below ground if you don’t stand out as a treasure hunter. That is where the Rover UC is at home.

On the move like a hiker
The telescopic probe doubles as a trekking pole: height-adjustable, light at around 0.5 kilograms and just 67 centimetres long when collapsed. Anyone passing by sees a hiker.

Analysis on your wrist
The smartwatch controls the scan and shows initial results right away. If needed, it switches to a fitness or compass view. The detailed analysis follows later on your laptop in Visualizer 3D Studio.

Signals for your ears only
Bluetooth headphones, vibration alerts and night mode keep your search quiet, even after dark.
OKM Rover UC
Metal Detector disguised as Trekking Pole with SmartwatchRover C4 vs. Rover UC
Both OKM Rover models are built around 3D Ground Scan technology with magnetic field sensors, and each has its own focus for specific field operations. Compare the Rover C4 and Rover UC on depth performance, operating modes, control, probes and special features – and decide which profile suits your project.
Whatever a data sheet can’t answer, we’ll clarify in a personal conversation, backed by more than 25 years of experience in detection technology. By phone, on a video call or in person at our manufactory in Altenburg, Germany: together, we’ll find the right model for your search.

From Survey Area to Dig Site
Four steps, one clear process:
Clear
Magnetometer
Surface junk causes interference. In Magnetometer mode it is quickly located and removed before the actual scan begins.
Scan
3D Ground Scan
The survey area is walked line by line. The smartwatch or touchscreen shows how many impulses and scan lines have been recorded.
Analyse
Visualizer 3D Studio
On the laptop, the measurement data becomes a colour-coded 3D visualisation showing the position and depth of detected objects underground. With the Rover UC, the smartwatch already gives you an initial assessment in the field.
Pinpoint
Pinpointer
Before you break ground, the Pinpointer determines the exact position of the target.
What Lies Hidden Below
Some treasures have lain in place for centuries: a coin hoard in a ploughed field, a forgotten chamber in a hillside, a gold vein in the rock. They are not waiting for chance – they are waiting for someone who searches with purpose.
A scan reveals where the ground behaves differently from its surroundings – and where it is worth digging. If you know the soil and your target in advance, the measurement data also gives you clues about the material of the detected object. With this technology, the big find at depths of up to 25 m comes within reach:
Treasures and precious metals
Coin hoards, jewellery and metal containers, ferrous or non-ferrous.
Cavities
Tunnels, chambers, bunkers and hidden rooms.
Indications of natural gold
Mineralisation in quartz veins and bedrock pointing to natural gold deposits.
Your Next Find Is Waiting
OKM Rover goes one step further than the classic 3D ground scanner: depending on the model, with a dedicated focus on covert searching or gold prospecting. There’s a reason the Rover is the best-selling series among OKM 3D ground scanners.

FAQ: OKM Rover Series
In 3D Ground Scan mode, the Rover UC achieves a depth performance of up to 20 metres, the Rover C4 up to 25 metres. How deep you can search in each case depends on the size of the object and the soil conditions. The Rover C4’s Mineral Scan does not provide a depth reading; instead, it shows zones of mineralisation.
The Rover UC is built for searches that can’t afford attention: disguised as a trekking pole and controlled by smartwatch. The Rover C4 is the all-rounder of the series and additionally offers Mineral Scan for gold prospecting. In a product consultation, we’ll work out together which model fits your project.
Yes – that’s what Mineral Scan with the super probe is for. It detects mineralisation in quartz veins and bedrock that points to natural gold deposits. The gold itself is detected indirectly via accompanying magnetic minerals.
A 3D ground scanner records anomalies in the Earth’s magnetic field and displays them in colour-coded form. From this, you can read position, depth and size and get indications of the material. This technology enables the impressive depth performance of up to 25 m and the detection of large finds.
The Rover models offer an excellent introduction to 3D Ground Scan technology without compromising on performance. Before you buy, we advise you personally; after your purchase, you receive training and support directly from the manufacturer.
