The New Dimension of Discovery
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.

While scanning with the GR-4 Dual Model, settings and results are displayed to the user on the integrated screen of the device. It also provides real-time detailed and 3D analysis through the G-Portal (Groundtech Portal) application, specifically developed for Android and iOS devices.

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.
This technology delivers superior performance, particularly in areas where standard detectors struggle, such as soils with high mineral content, saline soils, and coastal regions. The PI system can detect targets deep underground without being affected by mineral density or soil composition. This allows large metal masses, buried precious metals, or deep cavities to be detected with much clearer and more stable signals.
The GR-4 Dual allows for easy conversion by simply mounting the PI search coil onto the section where the magnetic sensor is attached, thanks to its modular design. 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.
Pinpointer Function 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.
Live Scanning Function With the Live Scanning Function, you can quickly and graphically detect underground objects. It allows for easy and quick detection of objects without being bound to a specific search pattern.
Detector Advanced Scan Mode The Detector Advanced Scan Mode allows users to make detailed settings, detect from deeper depths, distinguish between ferrous and non-ferrous metals, and detect valuable or non-valuable metals.
3D Ground Scanning Detector Mode The 3D Ground Scanning Detector Mode allows users to detect soil and metals using the detector function and analyze the results in 3D on the Groundtech Portal application.
