Groundtech GR-3 PLUS 3D Ground Scanner

Double your depth and supercharge your treasure hunting with the Groundtech GR-3 PLUS. This advanced model takes the ultra-lightweight, completely wireless design of the standard GR-3 series and upgrades the internal sensor system to reach extreme depths. Weighing only 600 grams (1.3 lbs), the GR-3 PLUS packs professional-grade geophysical exploration power into a highly portable, cable-free wand.

By measuring electromagnetic variances in the soil, the GR-3 PLUS maps out deeply buried treasures, magnetic metals, and hidden cavity structures like tunnels, ancient graves, caves, and chambers. Your scan data transmits instantly via Bluetooth to your smartphone or tablet, providing real-time, color-coded 3D graphic visualizations right in the palm of your hand.

Key Features

• Upgraded 15-Meter Depth Capacity: Peer deeper into the earth than ever before. The GR-3 PLUS doubles the depth range of the base model, reaching depths of up to 15 meters (approx. 49 feet) depending on soil structure and target size.
• Ultra-Lightweight & Cordless: Weighing just 600 grams, this compact stick-style scanner completely eliminates bulky external battery packs and tangled cords for maximum agility in the field.
• Real-Time 3D Visualization: Syncs seamlessly via Bluetooth to the custom 3D analysis app for Android and iOS. Instantly analyze target depth, size, and structural shape with intuitive color graphics that differentiate magnetic metals (iron/steel) from non-magnetic treasures (gold, silver, copper).
• 4 Advanced Scanning Modes: Fully adaptable to any terrain scenario with Automatic Ground Scanning, Manual Ground Scanning, Live Scan (for quick unbound target tracking), and a precise Pinpointer function to lock onto exact locations.
• Multi-Terrain Adaptability: Engineered to deliver stable, high-resolution subsurface maps across a variety of challenging ground conditions, including sandy beaches, heavily mineralized rocky hillsides, and dense clay soils.
