Description
Groundtech GR-4 Series
A New Dimension of Discovery
The next-generation GR-4 is an advanced ground scanning and detection system that allows you to detect underground anomalies, perform 3D analysis, and instantly evaluate results.
It offers integrated, multi-functional solutions for professional treasure hunters, archaeological researchers, and anyone seeking high-accuracy exploration of underground structures.
With its dual-sensor 3D ground scanning system, the GR-4 detects, measures, and pinpoints all targets — from buried metals and magnetic objects to graves, chambers, and tunnels.
Thanks to its high-resolution color display, you can instantly view, analyze, and precisely locate your results 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 display allows you to view all scanning modes, settings, and results directly on the device itself, ensuring fast and convenient standalone operation.
If desired, you can also save your scanning data with the G-PORTAL mobile application, perform detailed 3D and 4D analyses, and generate comprehensive reports.
This means the device provides both quick and practical standalone use and advanced analysis capabilities via the mobile app.
Its foldable modular body design, adjustable grip angle, and detachable sensor module make the GR-4 a pioneer in portability and field adaptability.
