Groundtech GR4 Underground Imaging Device: A New Dimension in Gradiometer Discovery

In treasure hunting, archaeological studies, and engineering projects, underground imaging technologies are becoming more critical every day. The new generation Groundtech GR4 Underground Imaging Gradiometer offers high accuracy and reliable field analysis with its advanced 3D ground scanning system and dual-sensor gradiometer technology.

From gold exploration to void detection, this model is preferred by professional users and is offered under the assurance of Cotyora Dedektör, providing expert support for high-end detection needs.

What is the Groundtech GR4 Underground Imaging Gradiometer?

The Groundtech GR4 is a professional gradiometer-based 3D underground imaging system capable of analyzing:

• Buried metal objects

• Magnetic field variations

• Void structures such as rooms, graves, and tunnels

• Archaeological remains with high resolution.

Thanks to the MFS-2 Dual Sensor Technology (Gradiometer) with a capacity of $\pm 2000 \mu T$, it precisely detects magnetic differences and presents detailed data for user analysis.

Advanced 3D Underground Imaging Technology

The Groundtech GR4 operates with three distinct scanning modes:

1. 3D Ground Scan

2. Live Scan

3. Pinpointer

These modes allow users to view underground imaging data instantly on the device's built-in color screen. Powered by a 240 MHz CPU and a 12-bit A/D converter, the captured data is processed rapidly and accurately. The 3D scanning system can reach depths of up to 15 meters (based on manufacturer data).

Standalone Operation and Portable Design

The Groundtech GR4 functions independently without the need for an external phone or tablet. All settings and analyses are controlled via the integrated display.

Its foldable modular body and adjustable grip angle provide:

• Easy transportation

• Quick setup

• Ergonomic use for long-term field operations.

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

The device establishes a wireless connection via Bluetooth 4.2 BLE with the G-Portal Android & iOS application. This enables:

• 3D and 4D data analysis

• Advanced reporting

• Data logging and storage

• In-depth office review.

This synergy offers the advantage of fast scanning in the field and detailed analysis in the office.

Difference Between GR-4 and GR-4 Dual

The standard Groundtech GR4 focuses on gradiometer imaging and does not include a metal detector system. However, the GR-4 Dual model integrates Pulse Induction (PI) metal detector technology.

GR-4 Dual Features:

• Pulse Induction technology (1 kHz frequency)

• Superior performance in highly mineralized soils

• Stable operation in salty ground and coastal areas

• Detector depth up to 3 meters (manufacturer data)

Thanks to its modular structure, the device can be transformed by attaching a PI search coil, allowing both 3D imaging and professional detector use in a single unit.
