Fusion Light is an easy-to-use ground scanner for treasure hunters who wish to seek buried artifacts and hidden treasures in cavities such as tombs, tunnels, and subterranean caches. The treasure detector is a special edition combining favorite application properties of the powerful Fusion Professional with the flexibility and usability of the Rover UC.
Operating modes of Fusion Light
3D Ground Scan allows treasure hunters to detect gold treasures and underground anomalies and visualize the scan data immediately on their smartphone via the Android App.
With its integrated Magnetometer, the Fusion Light can locate ferrous metals like militaria and iron boxes filled, e.g., with silver and gold coins, valuables, and precious artifacts.
Discover a new dimension of treasure hunting
Fusion Light, the compact treasure detector for beginners and treasure hunters with a small budget, convinces through its simple handling and easy transport – perfect to quickly achieve first successes in treasure hunting.
This device has it all: Fusion Light, the most lightweight device among our metal detectors and ground scanners, consists of a compact control unit with integrated sensors and is controlled via the Android App. The operating modes Magnetometer and 3D Ground Scan are essential for successful treasure hunts. The measurement results are visualized graphically with the Android App directly on the Smartphone (or Tablet) and can be further analyzed via the Visualizer 3D software on the Windows notebook.
Detect and analyze anomalies with a 3D ground scan
The 3D Ground Scan operating mode helps treasure hunters, military seekers, and historians track underground cavities and artifacts. Potential finds and discoveries can be displayed on the Android smartphone via the OKM Fusion Light App and saved for further analysis. Treasure hunters get a more accurate 3D image by transferring the scan data to the notebook PC and analyzing them with the software Visualizer 3D program.
Experience a Detailed 3D Visual Representation of What's Below
The state-of-the-art Visualizer 3D software allows the measurement data of the 3D Ground Scan to be displayed in a high-definition 3D graphic on the notebook. Following a quick and simple transfer of the stored scan data to the PC, you can understand the potential buried treasures' position, size, and depth even more accurately.
The Magnetometer Scans Objects of all Different Sizes
With the scan function, the magnetic field of the earth can be measured. Irregularities in the magnetic field show potential targets. In this process, artifacts hidden for a long time such as treasure chests, antique ammunition, and other ferrous objects can be identified. Experienced treasure hunters use the Magnetometer preceding the Ground Scan in succession to free the scan field of smaller objects nearby to the surface.

The laptop is included (1 license for Visualizer 3D Studio).Fusion Professional is more powerful and detects objects up to 20 m depth. It offers the SRIS search coil for scanning objects on the surface. The laptop is included (4 licenses for Visualizer 3D Studio). -
Does it detect if the item is worth the digging ( as if it’s a real treasure, and gives you the accurate dimensions to find the right spot to start digging job ?
Yes the OKM Fusion Light uses a 3D ground scan that can visualize what is underground by connecting the data to a smartphone or tablet using an android app. With its integrated Magnetometer, the Fusion Light is able to find ferrous metals like militaria and iron boxes filled e.g. with silver and gold coins, valuables, and other precious artifacts.
