Groundtech GR-4 Dual

Groundtech GR-4 Dual | 3D Ground Scanner

The Groundtech GR-4 Dual is a state-of-the-art 3D ground scanner and metal detector designed for professional prospectors, treasure hunters, and archaeological teams.
It combines the advanced MFS-2 Dual Sensor Technology with an optional Pulse Induction (PI) detection system, offering a unique dual capability: deep 3D scanning with instant data visualization, and conventional metal detection for quick verification.

Key Highlights:

• MFS-2 Dual Sensor for multi-field scanning and enhanced target discrimination.

• 3D Ground Scanning up to 15 meters (depending on soil conditions).

• Integrated PI (Pulse Induction) system for metallic confirmation up to ~3 meters.

• Six powerful scanning modes (3D, Live, Pinpointer, Quick Scan, Advanced Detector, Hybrid 3D+Detector).

• Full compatibility with Android/iOS applications for 3D visualization, saving, and sharing results.

• Long-lasting rechargeable Li-ion battery, ~10 hours of operation in 3D mode.

• Multi-language support is available both on the device and in the app.

• Official 2-year manufacturer warranty.

Why choose GR-4 Dual?

• Combines geological scanning and conventional detection in a single compact unit.

• Designed for serious applications: archaeological surveys, cavity and tunnel detection, treasure hunting, and verification in highly mineralized soils.

• The easy-to-use app interface reduces the time required to interpret data and make field decisions.

2) Quick Field Guide

1. Charge fully: Charge both the main unit and tablet before field use.

2. Assembly: Mount the MFS-2 sensor or PI coil, fix the shaft and tablet.

3. Power & Pair: Switch on the system, open the app, and connect via Bluetooth 4.2 BLE.

4. Select mode: Use 3D Ground Scan for detailed surveys, Live/Quick Scan for fast checks, PI mode for confirmation.

5. Grid setup: Walk the scan area in steady lines (forward & backward passes) to build a complete 3D map.

6. Instant analysis: View anomalies directly in the app, use Pinpointer for exact target localization.

7. Save & Share: Store scans for later review or share with your analysis team.

8. Document findings: Record soil conditions, depth, and settings for reference.

Pro tips:

• Walk slowly and consistently during scans to improve 3D accuracy.

• In highly mineralized soil, switch to PI mode for reliable confirmation.

• Keep a clear Bluetooth line-of-sight between the device and the tablet.

3) Scanning Modes :

1. 3D Ground Scanning

• Full 3D survey of the target area.

• Best for detailed ground analysis and identifying anomalies.

2. Detector Quick Scan

• Fast metal detection mode.

• Use for initial area check before detailed scanning.

3. Pinpointer

• Precise target localization.

• Use after locating a target on the 3D map for the exact digging spot.

4. Live Scanning

• Real-time data stream while moving.

• Best for quick exploration and rapid ground checks.

5. Detector Advanced Scan Mode

• Advanced detection with metal differentiation.

• Ideal for complex or mineralized environments.

6. 3D Ground Scanning Detector Mode (Hybrid)

• Combines 3D ground scanning with metal detection.

• Provides dual confirmation (map + metal signal).

4) Software & Data Management

• Intuitive mobile app interface (Android/iOS) with 25+ languages, including Arabic.

• Save and retrieve scanning sessions locally on the tablet.

• Built-in measuring tools: estimate coordinates, depth, and object size.

• Data sharing options for team collaboration.

• Frequent firmware/app updates ensure maximum accuracy.

 FAQ (Suggested)

Q: Does the GR-4 Dual require training?
A: Yes, for accurate results, a short training on scan grid setup and 3D data interpretation is recommended.

Q: How does it perform in mineralized soil?
A: The device uses a hybrid system (MFS-2 + PI mode) to handle high mineralization effectively, but results may still vary depending on soil type.

Q: What is the warranty period?
A: The official manufacturer’s warranty is 2 years.
