Gr-4 Dual

The Conrad GR-4 Dual Series Breaks New Ground Are you looking for a professional device capable of detecting underground structures, minerals, and hidden treasures with unparalleled accuracy? The Conrad GR-4 Series opens new horizons in exploration, combining the latest 3D ground scanning technology with a modular design for maximum field performance. Ideal for professional treasure hunters, archaeologists, and enthusiasts, the GR-4 Dual System immediate detection, analysis, and location of underground anomalies.
The new generation GR-4 is an advanced ground scanning and detection system that allows you to detect underground anomalies, perform 3D analysis, and evaluate the results instantly.
Conrad GR-4 Dual – Multiple Technologies for Maximum Performance6 Different Scanning features3D Ground Scan System, Detector Quick Scan System, Pinpoint Function, Direct Scan Function, Detector Advanced Scan Mode, and Detector Mode for 3D Ground Scanning as Standard Scanning.
Simple Design, Powerful PerformanceThe GR-4 is designed to be extremely simple and compact, making it accessible to everyone. The 3D Ground Scan System select the detection, measurement, and location of buried metal, magnetic objects, graves, chambers, and cavities, search as tunnels, underground. The specially designed Groundtech Portal – 3D Analysis software graphically displays magnetic (iron or steel) and non-magnetic (gold, silver, or copper) metals. Depending on the target size (diameter) and soil structure, depths of up to 15 meters* are accessible.
Newest Generation of 3D Ground Scanning Devices
The GR-4 Dual is an advanced ground scanning detector that allows you to detect underground anomalies and perform 3D analysis. Designed to be a practical and versatile metal detector and 3D ground scanner, the GR-4 Dual provides a comprehensive and multifunctional solution for professional treasure hunters, archaeological treasure hunters, and underground structure detectors. The device is equipped with six different scanning modes.
Multi-Language SupportThe GR-4 Dual is easy to use and is available in language options such as English, German, Spanish, Italian, French, Turkish, Russian, Chinese, Arabic, and Persian. Our mobile app also supports 25 languages, ensuring a seamless experience for users around the world.
Groundtech’s Optimized MFS-2 Dual Sensor TechnologyAchieve successful scanning results thanks to advanced sensor technology and a faster processor. The highly sensitive MFS-2 Dual Sensor Technology allows for more sensitive and deeper scanning. This advanced technology, which reduces the margin of error, ensures optimal scanning results. With a faster, processor the GR-4 Dual offers an enhanced and accurate scanning experience.
3D Graphics

Get results quickly thanks to clear graphics. When scanning with the GR Dual-4, settings and results are displayed to the user on the built-in display. It thus provides real-time, detailed 3D analysis through the G-Portal (Groundtech Portal) app, designed specifically for Android and iOS devices.
Groundtech GR-4 Dual features

The GR-4 Dual model is equipped with an integrated Pulse Induction (PI) detection system, in addition to 3D ground scanning capabilities.
This technology delivers superior performance, especially in areas where traditional detectors struggle, seeking as highly mineralized soils, saline soils, and coastal areas. The PI system can detect deep underground without being affected by mineral density or soil composition. This allows for the detection of large mineral blocks, buried precious metals, or deep cavities with clearer and more stable signals.
Thanks to its modular design, the GR-4 Dual allows for easy conversion by mounting a PI search coil on the magnetic sensor mounting plate. This malicious 3D ground scanning and professional PI searches using a single device. This feature provides users with two powerful technologies simultaneously, without the need to carry two separate devices. As a result, the GR-4 Dual provides a complete, standalone solution for multi-purpose fieldwork, deep searches, and challenging terrain conditions.
