GROUNDTECH GR4 Deep Seeking 3D Metal Detector

Depth: 15 meters depending on the size of the buried objective.

The new generation GR-4 is an advanced ground scanning and detection system that allows you to detect underground anomalies, perform 3D analysis, and evaluate the results instantly.

The next-generation ground scanning detector

6 different scanning features

For an engaging and thorough exploration experience.
3D Ground Scanning System, Detector Quick Scan System, Pinpointer Function, Live Scanning Function, Detector Advanced Scan Mode, and 3D Ground Scanning Detector Mode as standard scanning.

Simplified Design, Powerful Performance

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

Next-Generation Ground Scanning

Advanced Ground Scanning Detector with 3D Analysis
The GR-4 Dual Model is an advanced ground scanning detector that allows you to detect underground anomalies and perform 3D analysis. Designed as a practical and versatile metal detector and 3D ground scanner, the GR-4 Dual Model offers integrated and multi-functional solutions for professional treasure hunters, archaeological treasure seekers, and the discovery of underground structures. The device is equipped with six different scanning modes.

Multi-language support

Easy to use with multi-language options.
The GR-4 Dual model is easy to use with language options such as English, German, Spanish, Italian, French, Turkish, Russian, Chinese, Arabic, and Persian. Additionally, our mobile application supports 25 languages, ensuring a seamless experience for users worldwide.

Perfect MFS-2 Dual Sensor Technology by Groundtech

Get successful scanning results with advanced sensor technology and a faster processor.
High-sensitivity MFS-2 Dual Sensor technology allows you to carry out more sensitive and deeper scanning. This advanced sensor technology, which minimizes the margin of error, ensures you get perfect scanning results. Combined with a faster processor, the GR-4 Dual model provides an enhanced and precise exploration experience.

3D Graphics

Get the results quickly with the understandable graphics.

While scanning with the GR-4 Dual Model, settings and results are displayed to the user on the integrated screen of the device. It also provides real-time detailed and 3D analysis through the G-Portal (Groundtech Portal) application, specifically developed for Android and iOS devices.

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

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

If desired, you can save your scan data with the G - PORTAL mobile app, examine 3D and 4D analyses in more detail, and generate comprehensive reports. This allows the device to offer both fast and practical standalone use and advanced analysis capabilities with the mobile app.With its foldable modular 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.

Professional metal detectors locate metals buried for many years by detecting subtle environmental changes caused by these metals.

These detectors use bio-energy interaction, ionization technology, electromagnetic field detection, advanced microprocessor analysis, long-term soil disturbance detection, and sensor fusion. The longer the burial time, the easier it is to detect these metals due to more pronounced ion fields and electromagnetic signatures.

Practical Testing Methods:

  • Field Testing in Historic Sites: Test in areas with known buried metal objects, like historical battlefields or archaeological sites (with permission).
  • Using Known Buried Objects: Test in places where long-buried metals are documented, such as old farm fields or construction sites.
  • Avoid Air Testing: Do not test with unburied or freshly buried metals. These detectors work by detecting ionization fields around long-buried metals, unlike hobby detectors.
  • Avoid testing inside houses, buildings, or other structures: numerous cables, electrical systems, and other factors can interfere with the long-range detector's performance.

INTERNATIONAL CUSTOMERS

Import Duties, Taxes, and charges are not included in the item price or shipping charges. These charges are the buyer responsibility.

Please check with your country’s custom office to determine what these additional costs will be prior to buying.

** DetectorsPro is not responsible and does not accept returns for the incorrect handling of the equipment sold and can not guarantee the customer the discovery of valuable treasures or metals if in the place of search there is really nothing. Detectors Pro guarantees that the devices detect efficiently as they are constantly evaluated by detectorists and manufacturers to provide the best results. We suggest our clients before making any purchase that analyzes the equipment well since they are high-end and very modern equipment that can not be returned.
