Groundtech GR-4 Dual Ground Scanner

Advanced 3D Ground Scanner with Dual Sensor Technology
 
The GR-4 Dual is designed to be extremely simple and compact, making it accessible to everyone. The 3D Ground Scanning System enables the detection, measurement, and location of buried metals, magnetic objects, graves, rooms, and cavities such as tunnels underground. The specially prepared Groundtech Portal - 3D Analysis software graphically shows magnetic (iron or steel) and non-magnetic (gold, silver, or copper) metals. Depending on the target's size (diameter) and soil structure, depths of up to 15 meters* can be reached.

The GR-4 Dual model in the series is equipped with an integrated Pulse Induction (PI) detector system in addition to its 3D ground scanning capabilities.

This technology delivers superior performance, particularly in areas where standard detectors struggle, such as soils with high mineral content, saline soils, and coastal regions. The PI system can detect targets deep underground without being affected by mineral density or soil composition. This allows large metal masses, buried precious metals, or deep cavities to be detected with much clearer and more stable signals.


The GR-4 Dual allows for easy conversion by simply mounting the PI search coil onto the section where the magnetic sensor is attached, thanks to its modular design. This enables both 3D ground scanning and professional PI detector searches with a single device. This feature offers users two powerful technologies simultaneously, without the need to carry two separate devices. As a result, the GR- 4 Dual offers a complete, standalone solution for multi - purpose field work, deep searches, and challenging terrain conditions.
 
3D Graphics
While scanning with the GR-4 Dual Model, settings and results are displayed to the user on the integrated screen of the device. It also provides real-time detailed and 3D analysis through the G-Portal (Groundtech Portal) application, specifically developed for Android and iOS devices.
 
Next-Generation Ground Scanning
The GR-4 Dual Model is an advanced ground scanning detector that allows you to detect underground anomalies and perform 3D analysis. Designed as a practical and versatile metal detector and 3D ground scanner, the GR-4 Dual Model offers integrated and multi-functional solutions for professional treasure hunters, archaeological treasure seekers, and the discovery of underground structures. The device is equipped with six different scanning modes.
 
Perfect MFS-2 Dual Sensor Technology by Groundtech
High-sensitivity MFS-2 Dual Sensor technology allows you to carry out more sensitive and deeper scanning. This advanced sensor technology, which minimizes the margin of error, ensures you get perfect scanning results. Combined with a faster processor, the GR-4 Dual model provides an enhanced and precise exploration experience.
