CONRAD GR3
3D Ground Scanner | Compact & Lightweight | 7M Depth
Portable 3D Subsurface Imaging
The Groundtech GR3 (Conrad GR3) is a revolutionary compact 3D ground scanner designed for treasure hunters and surveyors who need power without the bulk. Weighing less than 600g, this telescopic sensor stick can easily be carried into difficult terrain where larger devices fail.
Using advanced CN-S Sensor Technology, the GR3 detects differences in the soil to locate buried anomalies such as caves, tunnels, graves, and metallic objects (gold, silver, copper, iron). It connects wirelessly to your own Android or iOS smartphone/tablet, instantly converting scan data into high-resolution 3D graphics.
With a detection capability of up to (7 meters in case we have a big target), the GR3 offers professional-grade analysis in a “Grab & Go” package. It requires no cables, no heavy battery packs, and no complex setup—just turn it on, connect via Bluetooth, and start scanning.
Functions & Technology
- 1. 3D Ground Scan
Allows you to measure and detect the position, depth, and dimensions of underground objects (rooms, tunnels, graves, metals) in full 3D graphics on your mobile device. - 2. Live Scan Mode
Provides a real-time 2D stream of what is beneath the sensor as you walk. This is perfect for quickly identifying targets without waiting for a full render. - 3. Pinpointer Function
Helps you locate the exact center of a potential target. This focused mode is essential for narrowing down the dig site after a general scan. - 4. Multi-OS Support
Unlike older devices locked to a specific specific PDA, the GR3 app works on both **Android** and **iOS** devices. Use the phone or tablet you already own. - 5. Telescopic Design
The device is hidden inside a compact, telescopic hiking stick. It extends for use and collapses for easy transport, making it highly discreet.
