Groundtech GR4 Dual Underground Imaging Device

Groundtech GR4 Dual Yer Altı Görüntüleme Cihazı – Discover What Lies Beneath

The Groundtech GR4 Dual Underground Imaging Device is an advanced system designed for professional treasure hunters, archaeologists, and engineers. Combining cutting-edge 3D underground imaging technology with an integrated Pulse Induction (PI) detector system, it delivers powerful performance in all types of terrain conditions.

For users seeking high-precision detection of buried metals, chambers, tunnels, and underground voids, the GR4 Dual offers maximum efficiency and reliability in the field.

Advanced 3D Underground Imaging & Gradiometer Technology

One of the strongest features of the Groundtech GR4 Dual is its MFS-2 dual-sensor gradiometer system (±2000 µT). This advanced gradiometer technology accurately analyzes magnetic field variations beneath the surface.

3D Scanning Modes:

• 3D Ground Scan

• Live Scan

• Pinpointer

• Detector Quick Scan

• Detector Advanced Scan

These modes allow users to monitor underground imaging data in real time directly on the device screen and precisely pinpoint targets.

Deep Detection Power with Pulse Induction (PI) Technology

Unlike conventional systems, the Groundtech GR4 Dual features an integrated Pulse Induction (PI) metal detector operating at 1 kHz frequency.

• Up to 3 meters detection depth (detector system)

• Up to 15 meters depth with 3D scanning system

It performs exceptionally well in:

• Salty soils

• Highly mineralized ground

• Coastal regions

• Challenging terrain conditions

Large metal masses and underground void structures that standard detectors struggle to identify can be detected clearly and powerfully with PI technology.

Built-in Display & Standalone Operation

Many underground imaging devices require external smartphones or tablets. The Groundtech GR4 Dual features a built-in color display, allowing it to operate independently.

• 240 MHz CPU

• 12-bit A/D converter

• Bluetooth 4.2 BLE connectivity

• Type-C fast charging

• 3.7V Li-ion rechargeable battery

Approximate operating times:

• 10 hours (3D scanning system)

• 6 hours (Pulse Induction system)

This ensures uninterrupted performance during extended field operations.

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

Scan data collected with the Groundtech GR4 Dual can be analyzed in detail via the G-PORTAL mobile application.

• Compatible with Android & iOS

• 3D and 4D analysis features

• 25 language support

• Data storage and archiving

This allows users to review, analyze, and plan excavation strategies with greater accuracy and confidence.

Modular & Portable Design

Its foldable modular structure ensures easy transportation. The adjustable grip angle provides ergonomic comfort during long operations.

• Operating temperature: 0°C to 70°C

• Storage conditions: -20°C to 60°C

This makes the GR4 Dual suitable for both individual users and professional organizations.
