GR-4 DUAL
advanced ground scanning and detection system
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.
6 different scanning features
For an engaging and thorough exploration experience.
Simplified Design, Powerful Performance
Compact and accessible to everyone
Next-Generation Ground Scanning
Advanced Ground Scanning Detector with 3D Analysis
GR-4 DUAL GROUND SCANNER Features
- 3D Ground Scanning System, Detector Quick Scan System, Pinpointer Function, Live Scanning Function, Detector Advanced Scan Mode, and 3D Ground Scanning Detector Mode as standard scanning.
- 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 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.
- The GR-4 Dual model is easy to use with language options such as English, German, Spanish, Italian, French, Turkish, Russian, Chinese, Arabic, and Persian. Additionally, our mobile application supports 25 languages, ensuring a seamless experience for users worldwide.
GR 4 DUAL 3D Graphics
Get the results quickly with the understandable 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.
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.
Quick and Easy Underground Scanning: On the Trail of Valuable Metals
Pinpointer Function The Pinpointer Function helps you find the pinpoint location of objects. Thanks to its specially developed software and hardware sensors, it can detect from significant depths.
Live Scanning Function With the Live Scanning Function, you can quickly and graphically detect underground objects. It allows for easy and quick detection of objects without being bound to a specific search pattern.
Detector Advanced Scan Mode The Detector Advanced Scan Mode allows users to make detailed settings, detect from deeper depths, distinguish between ferrous and non-ferrous metals, and detect valuable or non-valuable metals.
3D Ground Scanning Detector Mode The 3D Ground Scanning Detector Mode allows users to detect soil and metals using the detector function and analyze the results in 3D on the Groundtech Portal application.
