Conrad GR-4 Dual – Professional Metal Detector with Dual Sensor Technology and 3D Ground Scan

The Conrad GR-4 Dual (GR-4 Double) represents one of the most advanced solutions on the market for underground detection, combining two cutting-edge technologies: 3D ground scanning and pulse induction (PI). This multifunctional device is designed to meet the needs of professional treasure hunters, archaeologists, geologists, and underground explorers who demand precision, depth, and reliability.

✅ Advanced Features of the Conrad GR-4 Dual:

• MFS-2 Dual Sensor Technology for optimized detection of metals and cavities.

• 6 integrated scan modes: 3D ground scan, fast scan, pinpointing, direct scan, advanced mode, and PI detector mode.

• Integrated Pulse Induction (PI) Technology: excellent performance in mineralized, saline, or difficult soils.

• Detection depth up to 15 meters with the 3D system – up to 3 meters with the PI system.

• Integrated color screen + G-Portal 3D/4D application on Android & iOS for detailed real-time graphical analysis.

• Multilingual operation: device in 11 languages, mobile application in 25 languages.

• Rechargeable lithium battery, Bluetooth 4.2 connection, compact and modular design.

⚙️ A 2-in-1 Solution for All Terrains

The GR-4 Dual is both:

• A high-performance 3D ground scanner for locating anomalies, cavities, chambers, or tunnels.

• A powerful PI metal detector, capable of locating deep metallic objects, even in complex soils.

Its modular design allows you to easily switch from 3D mode to PI mode, without changing devices. Ideal for those who wish to optimize their efficiency in the field.
