Gr 4

Groundtech GR-4 Series

The New Dimension of Discovery

The next-generation GR-4 is an advanced ground scanning and detection system that enables you to detect subsurface anomalies, perform 3D analysis, and evaluate results instantly.
It offers integrated, multi-functional solutions for professional treasure hunters, archaeological researchers, and anyone who wants to work with high accuracy on underground structures.

With its dual-sensor 3D ground scanning system, the GR-4 detects, measures, and locates all targets, from buried metals to magnetic objects, as well as void structures such as graves, rooms, and tunnels.
Thanks to its high-resolution color screen, you can instantly view, analyze, and clearly identify your targets in Live Scan, Pointer, and 3D ground scanning modes.

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

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

With its foldable modular body structure, adjustable grip angle, and removable sensor module, the GR-4 is a leader in its class in terms of portability and field adaptability.

GR-4 DUAL
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 in areas where standard detectors struggle, such as soils with high mineral content, salty soils, and coastal areas.

The PI system can detect targets deep underground without being affected by mineral density and soil composition.
This allows large metal masses, buried precious metals, or deep void structures to be detected with much clearer and more stable signals.

Thanks to its modular design, the GR-4 Dual allows for easy conversion by simply mounting the PI search coil onto the section where the magnetic sensor is attached. 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.
