More Details
The ground scanner Rover C4 is an easy-to-use multi-purpose treasure and void detector. The detector supports treasure hunters and archaeologists in finding long-time buried treasures such as relict, coins, vessels and jewelry as well as underground structures like tunnels, caves, chambers and graves. The measured data can be viewed and analyzed in the Visualizer 3D Studio Software.

- Including detection software Visualizer 3D Studio Standard Edition
Simple Operation via Touchscreen

The Rover C4 is controlled via color touchscreen with multilingual user interface. This allows a fast and easy operation and configuration of the metal detector. The detector can also be operated by using the alternative buttons.After selecting your preferred language, it will be indicated in the toolbar icon with the 2-letter-code according to ISO-639-1. The Rover C4 provides the following languages:
- عربي (AR)
- Deutsch (DE)
- Ελληνικά (EL)

Treasure Hunting in the Dark thanks to LED Lighting

The embedded LEDs in the bottom side of the Control Unit are gradually adjustable based on your environment. This can be particularly useful when scanning in narrow and dark tunnels or at night.
Interchangeable Probes
After connecting the desired probe to the Rover C4 Control Unit, the detector is ready to scan.
The Standard Probe can be used for the operating modes 3D Ground Scan and Magnetometer. It is attached directly to the unit and thus very easy to carry.
The Super Sensor is used for all operating modes including Mineral Scan and Pinpointer. Moreover, it provides 3D ground scan images in higher resolution. It is connected via cable and carried separately.
Immediate Feedback via LED Orbit
The Super Sensor and Standard Probe are equipped with an innovative LED Orbit that indicates underground targets immediately during the scan. This basic target discrimination visualizes detected metals and voids in different colors.
Treasure Detector Operating Modes

One of the most versatile operating modes in our 3D metal detectors is 3D Ground Scan. This function is used to scan a rectangular area to obtain measuring data from underground structures and objects.
However, in order to perform extensive ground measurements and achieve the maximum detection performance, we recommend using the operating modes Magnetometer, 3D Ground Scan and Pinpointer. The Mineral Scan mode is a Rover C4 add-on for gold prospectors.
Magnetometer: Use Magnetometer to clear the scan field of small metal items like nails, cans, screws and wires near the surface.
3D Ground Scan
3D Ground Scan provides a graphical measurement of any area for further analysis in the detection software Visualizer 3D Studio.
Pinpointer: With Pinpointer detectorists locate buried coins, rings, jewelry and similar treasure objects and artifacts more precisely.
Mineral Scan: Mineral Scan is used to locate natural gold deposits.
The fewer metal items near the surface, the better your 3D Ground Scan results. After clearing your scan field with Magnetometer, you can also find larger metal targets which are located deeper underground. Analyze your 3D Ground Scan images in Visualizer 3D Studio and locate the detected objects more precisely with the Pinpointer mode.
Ground Scanning with Metal Detector Rover C4

Detectable items that can be found with the 3D ground scanner Rover C4 are:
- Lost treasures and hidden precious metals
treasure chests, gold coins, jewelry, silverware, relics, artifacts, valuables, buttons, medals etc. - Underground voids and cavities
tunnels, graves, chambers, cellars, sepulchers, dugouts, shelters, bunkers etc. - Natural gold minerals
gold ore, gold deposits, gold veins etc.
Scan Analysis with Visualizer 3D Software

After transferring your 3D Ground Scans and Mineral Scans to the notebook with Visualizer 3D Software, the scan data are ready for further analyses in order to:
- Identify Potential Objects and Hidden TreasuresThe detected targets are represented by different colors. The color information will tell you if it is a ferrous metal (iron, steel), precious metal (gold, silver, bronze, copper) or a void structure (cave, tunnel, grave, chamber).
- Determine Position and DepthThe software shows the position of the detected anomalies and – according to the chosen soil – how deep the target is buried in the ground.
- Calculate Object DimensionsBesides depth information, Visualizer 3D Studio can also calculate the dimensions of hidden targets and buried items.
