GR-4 DUAL Ground Scanning Detector
The new generation GR-4 is an advanced ground scanning and detector system that allows you to detect underground anomalies, perform 3D analysis, and instantly evaluate the results. COMING SOON!
GROUNDTECH GR-4 DUAL
NEW GENERATION | Standalone 3D Scanner & PI Detector
“Operates independently without needing a phone or tablet”
Advanced Standalone Technology
The new generation Groundtech GR-4 Dual allows you to detect anomalies underground, perform 3D analysis, and evaluate results instantly. Unlike previous models, the GR-4 Dual features a built-in color screen, allowing for completely independent operation without the need for a phone or tablet.
Equipped with both a Dual-Sensor 3D System and an integrated Pulse Induction (PI) Detector, this device provides superior performance in highly mineralized soils, saline areas, and coastal regions. It effortlessly detects large metal masses, buried precious metals, and deep void structures such as tombs and tunnels.
Comparison: GR-4 vs. GR-4 Dual
| Feature | Standard GR-4 | GR-4 Dual (Advanced) |
|---|---|---|
| System Type | 3D Earth Scanner | 3D Scanner + PI Metal Detector |
| Pulse Induction | Not Included | Integrated (1 kHz) |
| Mineralized Soil | Standard Performance | Superior (PI Tech) |
| Battery Life | 10 Hours | 6 Hours (PI) / 10 Hours (3D) |
5 Advanced Operating Modes
- 1. 3D Ground Scanning
Detects anomalies underground (metals, magnetic objects, void structures) and allows for 3D analysis directly on the device screen. - 2. Live Scanning
Provides real-time visual feedback of what is currently beneath the sensor. - 3. Pinpointer
Helps in precisely locating the exact center of the detected target. - 4. Detector Quick Scanning
Uses the PI system for fast detection of ferrous and non-ferrous metals. - 5. Detector Advanced Scanning
A deeper, more detailed Pulse Induction mode for challenging terrains and deep targets.

Frequently Asked Questions
Q: Does it work without a phone?
A: Yes! The new GR-4 Dual has a built-in color screen that displays all scanning results instantly. You can operate it completely independently.
Q: What is the Pulse Induction (PI) system for?
A: The PI system allows for deep metal detection in difficult soils (salty/mineralized) where standard detectors fail. It is integrated into the GR-4 Dual.
Q: How deep can it go?
A: The 3D Ground Scanning system can reach up to 15 meters, while the Pulse Induction detector system works effectively up to 3 meters depth.
Q: Can I still use my phone?
A: Yes. You can save data and perform detailed 3D/4D analysis using the G-Portal mobile application on Android or iOS.
