The next-generation Groundtech GR4 Ground Imaging Device Gradiometer delivers high accuracy and reliable analysis in the field with its advanced 3D ground scanning system and dual-sensor gradiometer technology.

From gold prospecting to cavity detection, this model offers a wide range of applications and is available with professional support through altınordu'da ordu dedektör

What is the Groundtech GR4 Ground Imaging Device Gradiometer?

The Groundtech GR4 Ground Imaging Device Gradiometer is a professional gradiometer-based 3D ground imaging system capable of detecting:

• Buried metal objects

• Magnetic field variations

• Cavities such as rooms, graves, and tunnels

• Archaeological remains

With its MFS-2 Dual Sensor Technology (Gradiometer) ±2000 µT capacity, it precisely detects magnetic differences and presents detailed data for analysis.

Advanced 3D Ground Imaging Technology

The Groundtech GR4 Ground Imaging Device Gradiometer operates with three different scanning modes:

• 3D Ground Scan

• Live Scan

• Pinpointer

These modes allow users to view ground imaging data instantly on the device’s built-in color display. Thanks to its 240 MHz CPU and 12-bit A/D converter, collected data is processed quickly and accurately.

The 3D scanning system provides scanning capability up to 15 meters depth (according to manufacturer data).

Standalone Operation & Portable Design

The Groundtech GR4 Ground Imaging Device Gradiometer works independently without the need for a smartphone or tablet. All settings and analyses can be managed directly from the integrated screen.

With its foldable modular body structure and adjustable grip angle, it offers:

• Easy transportation

• Fast setup

• Ergonomic use during long operations

It ensures maximum practicality in fieldwork.

Advanced 3D / 4D Analysis with G-PORTAL Mobile Application

The device connects wirelessly via Bluetooth 4.2 BLE to the G-Portal Android & iOS application.

This enables:

• 3D and 4D analysis

• Advanced reporting

• Data storage

• Detailed office-based review

It combines fast field scanning with in-depth office analysis capabilities.

Difference Between GR-4 and GR-4 Dual

The standard Groundtech GR4 Ground Imaging Device Gradiometer model does not include a built-in metal detector system.

The GR-4 Dual model integrates Pulse Induction (PI) metal detector technology.

GR-4 Dual Features

• 1 kHz Pulse Induction technology

• Superior performance in highly mineralized soils

• Stable operation on salty ground and coastal areas

• Detection depth up to 3 meters (manufacturer data)

Thanks to its modular design, the PI search coil can be attached easily, converting the system into a dual-function device. This eliminates the need to carry two separate devices, offering both 3D ground imaging and professional PI metal detection in one system.
