    Experience more balanced detector design, improved multilevel lighting and simplified wireless data transfer - for your convenient and comprehensive treasure hunt.


    Intuitive control via touchscreen and hardware buttons facilitate the use of the compact detector. Individual settings such as Language and Brightness further improve the easy handling.


    The treasure hunters' favorite OKM detector Rover C4 supports the Operating Modes Magnetometer, 3D Ground Scan, Pinpointer and Mineral Scan. This provides all necessary steps for a comprehensive exploration of the subsurface.


    Both the easy-to-use Standard Probe and the high-resolution Super Sensor are equipped with the innovative LED Orbit. This exclusive feature indicates target objects such as ferromagnetic metal objects as well as voids in real-time by different colors.


    Visualizer 3D Studio displays your Pinpointer scans in real-time and ground measurements in 3D. This allows you to determine the size, position and depth of target objects more precisely before excavation.

    Simple Operation via Touchscreen

    The Rover C4 is controlled via color touchscreen with multilingual user interface. This allows easy operation and configuration of the metal detector. The detector can also be operated using alternative buttons and the brightness of the screen can be individually adjusted.

    Immediate Feedback via LED Orbit

    The detector is also equipped with an innovative LED orbit, that indicates underground targets visually. While scanning the ground this LED sphere emits colored light to visualize detected metals and cavities immediately.

    Operating Modes of Rover C4

    3D Ground Scan allows to create 3D images of the underground and find buried coins, rings, jewelry, and similar treasure objects and artifacts.

    Mineral Scan is used to locate natural gold deposits.

    Ground Scanning with Metal Detector Rover C4

    One of the most versatile operating modes in our 3D metal detectors is Ground Scan. This function is used to scan a rectangular area to obtain measuring data from underground structures and objects.

    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, statues, general 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.

    By walking over the field in a certain manner (Parallel or Zig-Zag) the treasure hunter scans the area of interest. With all recorded data the Visualizer 3D Software creates a 3D image that represents all detected underground objects. Thus, you know where and how deep the located treasures are in the ground.

    3D Data Analysis with Visualizer 3D Software

    All data that has been recorded with the Rover C4 metal detector during a ground scan or mineral scan can be transferred to the Visualizer 3D Software to process a detailed three-dimensional analysis.

    During Analysis

    • Identify potential objects and hidden treasures
      You will see the targets 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 depth
      The 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 dimensions
      Besides depth information Visualizer 3D can also calculate the dimensions of hidden targets and buried items.
