More Details

The GR-3 device is designed as a compact, stick-shaped ground scanner probe. It performs ground scanning by capturing subsurface data, which is then transmitted and visualized as detailed 3D graphics using a dedicated analysis app. This provides prospectors with powerful tools to interpret findings—such as the type, size, and depth of buried objects—through an intuitive, visual interface.

Despite its advanced features, GR-3 is offered at an accessible price point, making it ideal for beginners and hobbyists. At the same time, it delivers the reliability and performance that professional treasure hunters require.

Key Features of the GR-3

Multi-Purpose Functionality
The GR-3 is a versatile 3D ground scanning metal detector suitable for detecting:

• Precious metals: Gold artifacts, ancient coins, gold jewelry, and hidden treasures.
• Non-ferrous metals: Items made of silver, bronze, or copper.
• Ferrous metals: Iron, steel, and iron-based alloys.
• Subsurface voids: Cavities, tunnels, bunkers, and chambers.

3D Ground Scan Technology

At the core of the GR-3 is its integrated dual CN-D Sensor system, which provides high-resolution data by penetrating deep into the ground. This advanced sensor setup ensures precise results and detailed 3D visualization of underground structures.

Detection Modes

• 3D Ground Scan Mode
  The primary scanning mode, allowing users to perform automatic or manual ground scans and view results via the mobile app.
• Live Scan Mode
  Provides real-time 2D visualization of the ground, displaying changing color patterns based on detected materials as the probe passes over them.
• Pinpointer Mode
  Ideal for precisely locating objects during excavation, typically after identifying a target area with a full ground scan.

3D Analysis Application

The GR-3 is compatible with both Android and iOS devices. The companion analysis app renders scanned data in 3D, showing the underground landscape and highlighting potential targets such as tunnels or metallic objects. Users can analyze key details like:

• Target location
• Estimated depth
• Metal type

Wireless Connectivity

The device transmits data via Bluetooth 4.2 BLE, offering a wireless range of up to 50 meters. This allows seamless connection between the scanner and the mobile device for efficient data processing and analysis.

Rechargeable Power

Powered by a built-in 3.7V lithium-ion battery, the GR-3 can be recharged using any 5V Micro-USB source or portable power bank, making it convenient for extended field use.

Note: Maximum detection depth depends on soil composition and the size of the buried object. All depth values are approximate.
