Special Features Of Rover C4

  • Supported operating modes: Ground Scan, Pinpointer, Mineral Scan, Magnetometer
  • Graphical user interface in many different languages
  • Operational touchscreen with alternative hardware buttons
  • Improved multilevel LED lighting for usage of the detector in darkness
  • Integrated battery
  • Simplified wireless data transfer

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.

Scan Functions Of Rover C4

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.

Buried objects are indicated by different colors in a graphical 3D representation.
