Conrad GR-4 – Multiple Technologies for Maximum Performance

6 Different Scanning Features

3D Ground Scanning System, Detector Quick Scan, Pinpoint Function, Direct Scan Function, Detector Advanced Scan Mode, and Detector Mode for 3D Ground Scanning as Standard Scanning.

Simple Design, Powerful Performance

The GR-4 is designed to be extremely simple and compact, making it accessible to everyone. The 3D Ground Scanning System enables the detection, measurement, and identification of buried metals, magnetic objects, graves, chambers, and cavities, such as tunnels, underground. The specially designed Groundtech Portal – 3D Analysis software graphically displays magnetic (iron or steel) and non-magnetic (gold, silver, or copper) metals. Depending on the target size (diameter) and soil structure, depths of up to 15 meters* are accessible.

The Newest Generation of 3D Ground Scanning Devices

The GR-4 is an advanced ground scanning detector that enables you to detect underground anomalies and perform 3D analysis. Designed to be a practical and versatile metal detector and 3D ground scanner, the GR-4 provides a comprehensive and multi-functional solution for professional treasure hunters, archaeological treasure hunters, and underground structure detectors. The device is equipped with six different scanning modes.

Multi-Language Support

The GR-4 is easy to use and is available in language options such as English, German, Spanish, Italian, French, Turkish, Russian, Chinese, Arabic, and Persian. Our mobile app also supports 25 languages, ensuring a seamless experience for users around the world.

Groundtech’s Optimized MFS-2 Dual Sensor Technology

Achieve successful scanning results thanks to advanced sensor technology and a faster processor. The highly sensitive MFS-2 dual sensor technology allows for more sensitive and deeper scanning. This advanced technology, which reduces the margin of error, ensures optimal scanning results. With a faster processor, the GR-4 delivers an enhanced and accurate scanning experience.

3D Graphics

Get results quickly thanks to clear graphics. When scanning with the GR-4, settings and results are displayed to the user on the built-in display. It also provides real-time, detailed 3D analysis through the G-Portal (Groundtech Portal) app, specially designed for Android and iOS devices.

GROUNDTECH GR-4 Features

The new generation GR-4 is an advanced ground scanning and detection system that enables you to detect any underground anomalies, perform 3D analysis, and evaluate the results immediately. It offers integrated, multi-functional solutions for professional treasure hunters, archaeologists, and anyone who wants to work with high precision in underground structures.

The GR-4 detects, measures, and locates all targets, from buried metals to magnetic objects, as well as empty structures such as graves, rooms, and tunnels, using its dual-sensor 3D ground scanning system. Thanks to its high-resolution color display, you can clearly view, analyze, and identify your targets in live, cursor, and 3D ground scanning modes. The device operates independently without the need for a phone or tablet. Thanks to its built-in color display, you can view all scan modes, settings, and results directly on the device itself, allowing you to use it independently without a phone or tablet.

If desired, you can save scan data using the G-PORTAL mobile app, examine 3D and 4D analyses in greater detail, and generate comprehensive reports. This allows the device to offer quick and convenient standalone use and advanced analysis capabilities with the mobile app. Thanks to its modular, foldable body structure, adjustable grip angle, and removable sensor module, the GR-4 is a leader in its class in terms of portability and field adaptability.
