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, 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.

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.

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.

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.
