The GROUNDTECH Conrad GR3 Plus Deep Seeking 3D Metal Detector (Dual Sensor) is a highly advanced ground scanning device that can detect and analyze differences beneath the surface. With its 3D analysis capability, it can accurately locate and measure buried metalsmagnetic objects, and cavities such as tombs, rooms, and tunnels. Depth: 15 meters/49 ft depending on the size of the buried objective. The specially designed software provides visual representation of both magnetic (iron or steel) and non-magnetic (gold, silver, or copper) metals for precise detection.

GROUNDTECH GR-3 PLUS Deep Seeking 3D Metal Detector
Detection Depth: Up to 15 meters, depending on the size and type of the buried object.

The GR-3 PLUS is a compact, lightweight 3D ground scanner designed for treasure hunters of all levels. With its user-friendly design and advanced technology, it allows for precise detection of deeply buried objects and provides visual data through an intuitive 3D analysis app, compatible with both Android and iOS devices.

Shaped like a sleek handheld probe, the GR-3 PLUS conducts detailed ground scans and transmits the data wirelessly to your mobile device. The analysis app transforms this data into high-resolution 3D visuals, enabling users to accurately assess target characteristics such as metal type, size, and depth.

Despite its affordable price, the GR-3 PLUS offers professional-grade performance, making it a valuable tool for beginners, hobbyists, and seasoned treasure hunters alike.

Advanced 3D Ground Scanning Technology


Equipped with dual high-precision CN-D sensors, the GR-3 PLUS provides exceptional depth penetration and detailed 3D visualizations for accurate analysis.

Detection Modes

  • 3D Ground Scan Mode
    The most widely used mode, it allows for scanning in automatic or manual operation. Data is processed and displayed in 3D via the analysis app.
  • Live Scan Mode
    Provides real-time scanning with a 2D color visualization that changes dynamically based on the material detected.
  • Pinpointer Mode
    Helps accurately locate metal objects during excavation after an initial scan.

3D Analysis App
Visualize scan data in 3D directly on your smartphone or tablet using the dedicated GR-3 PLUS app. The app offers a suite of analysis tools to determine the target's position, metal type, and depth with precision.

Wireless Connectivity
Bluetooth 4.2 BLE technology enables seamless wireless transmission of scan data up to a 50-meter range.

Rechargeable Battery
Powered by a built-in 3.7V lithium-ion battery, the device can be recharged via Micro-USB or portable power sources like power banks.
