How deep would you like to go?

0M

Solve the mystery of every buried object with a high sensitivity of detection.

You can carry out scanning up to a 0 meter depth depending on the soil structure and the size of objects. Get results far beyond those achievable by standard detectors.

** Variable depending on the soil structure and the size of buried objects as well as the scanning function.

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. It offers integrated, multi- functional solutions for professional treasure hunters, archaeological researchers, and anyone who wants to work with high accuracy in underground structures.

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, using its dual-sensor 3D ground scanning system. Thanks to its high- resolution color display, 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. Thanks to its built -in color screen, you can view all scanning modes, settings, and results directly on the device itself.This allows you to use it independently without needing a phone or tablet.

If desired, you can save 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.
