GR-4

Groundtech GR-4 Series

The New Dimension of Discovery

The new-generation GR-4 is an advanced ground scanning and detector system that allows you to detect underground anomalies  , perform 3D analysis, and instantly evaluate results . It offers integrated, multifunctional solutions for professional treasure hunters, archaeological researchers, and anyone who wants to work with high accuracy in underground structures .

The GR-4’s dual-sensor 3D ground scanning system detects, measures, and locates all types of targets, from buried metal and magnetic objects to cavernous structures like tombs, chambers, and tunnels.  Its high-resolution color display lets you instantly view and analyze your results in Live Scan, Pointer, and 3D ground scanning modes, allowing you to clearly identify your targets.

The device can operate independently without needing a phone or tablet . Its built-in color display allows you to view all scanning modes, settings, and results directly on the device . This allows you to use it independently without needing a phone or tablet .

If you prefer, you can save your scan data with the G-PORTAL mobile app , analyze 3D and 4D data in more detail, and generate comprehensive reports. This allows the device to offer both fast and practical standalone operation and advanced analysis capabilities with the mobile app .

Thanks to its foldable modular body, adjustable grip angle, and removable sensor module, the GR-4 leads its class in terms of ease of transport and field compatibility. The

GR- 4 Dual model in the series , in addition to its 3D ground scanning capabilities , is equipped with an integrated Pulse Induction (PI) detector system . This technology provides superior performance , particularly in areas where standard detectors struggle, such as highly mineralized ground, salty soils, and coastal areas .

The PI system can detect deep targets without being affected by mineral density or soil structure . This allows for the detection of large metal masses, buried precious metals, or deep void structures with much clearer and more stable signals.

Thanks to its modular design, the GR-4 Dual easily integrates a PI search coil into the magnetic sensor compartment , enabling conversion. This allows users to perform both 3D ground scanning and professional PI detector search with a single device . This feature offers users two powerful technologies simultaneously, without having to carry two separate devices.

As a result, the GR-4 Dual offers a complete solution for multi-purpose field work , deep exploration and difficult terrain conditions .
