Groundtech GR-4 Dual 3D Ground Scanner and Metal Detector
Groundtech GR-4 Dual 3D Ground Scanner and Metal Detector combines a built-in display with pulse-induction search. Ground scanning and metal detection can be selected for different field tasks.
Ground scanning can be reviewed on the device’s own screen without a phone. The metal detector system adds a separate search option for conductive targets in difficult ground.
Groundtech GR-4 Dual 3D Ground Scanner and Metal Detector Technology
The Groundtech GR-4 Dual 3D Ground Scanner and Metal Detector can survey underground anomalies and display results on its built-in color screen. Its 3D ground scanning data may also be reviewed in the G-Portal app when a more detailed record is needed.
The dual-sensor ground scanner supports 3D analysis, while the pulse-induction metal detector is intended for buried metal targets. Choose ground scanning or metal detection according to the target and record the soil conditions before interpreting a result.
Ground Scanning Comparison: GR-4 3D Ground Scanner vs. GR-4 Dual 3D Ground Scanner and Metal Detector
| Feature | GR-4 3D Ground Scanner | GR-4 Dual 3D Ground Scanner and Metal Detector |
|---|---|---|
| System Type | 3D Earth Scanner | 3D Scanner + PI Metal Detector |

Ground Scanning and Metal Detection 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.

Ground Scanner and Metal Detector FAQs
Can the Groundtech GR-4 Dual 3D Ground Scanner and Metal Detector perform ground scanning without a phone?
Yes. This ground scanner has a built-in color display for field results, and the metal detector system can be used as a separate mode. A phone remains optional for G-Portal analysis.
What does pulse induction add to the Groundtech GR-4 Dual 3D Ground Scanner and Metal Detector during metal detection?
The pulse-induction metal detector mode is designed for buried metal targets in mineralized or saline ground. The 3D ground scanner mode serves a different survey purpose, so select the relevant mode for each location.
What depth settings does the Groundtech GR-4 Dual 3D Ground Scanner and Metal Detector specify for ground scanning and metal detection?
Groundtech states up to 15 meters for 3D ground scanning and up to 3 meters for the metal detector system, subject to target size and soil. Those ground scanner and metal detection figures are conditional specifications, not a guarantee of a find.
Can a phone be used with the Groundtech GR-4 Dual 3D Ground Scanner and Metal Detector for ground scanning analysis?
Yes. The ground scanner can send data to the G-Portal app on Android or iOS for further 3D/4D analysis. The metal detector and on-device display still allow standalone field use.
