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.
Quick and Easy Underground Scanning
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.

The GR-3 is designed to be extremely simple and compact, making it accessible to everyone.
It does not have any cables or heavy batteries. Thanks to its lightweight design, the user scans the ground and the data received during the scan is displayed on the screen of a mobile device such as a tablet or phone in real-time.
The results on the screen can be analyzed immediately after the scanning and measuring process is finished. The data received can be stored on your mobile device such as a tablet or phone and can be re-evaluated in detail when needed.
The depth and diameter (size) of the target (metal and/or cavity) can be quickly determined thanks to the software's options.
The GR-3 is a multi-purpose device that can be used in all types of terrain (sandy, rocky or clayey).
GR-3 is available in two different models;
GR-3 model has a
high precision single sensor system
The GR-3 Plus model has a
- Wireless data transfer
- 3D Analysis app specially developed for Android and IOS
- Automatic and Manual, 3D ground scanning function
- Live scan and Pinpointer function
- 5 volt micro usb charging (can be charged with portable power supplies)
