Groundtech GR-3 3D Ground Scanner

Uncover the secrets of the deep without being weighed down. The Groundtech GR-3 is an ultra-compact, wireless 3D ground scanner designed for treasure hunters, relic seekers, and archaeologists who demand deep-seeking technology in a highly portable format. Say goodbye to heavy batteries and tangled cables—the GR-3 packs advanced subsurface imaging into a sleek, handheld design that weighs just 600 grams (1.3 lbs).

By measuring natural electromagnetic variances in the soil, the GR-3 effortlessly maps out buried treasures, magnetic metals, and hidden cavity structures like tunnels, graves, and chambers. Your scan data is transmitted 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

• Ultra-Lightweight & Cordless: Weighing only 600 grams, this compact stick-style scanner eliminates bulky battery packs and cables, making it exceptionally easy to transport and operate during long days in the field.
• Impressive 7-Meter Depth: Penetrate deep into the earth to find hidden targets. The GR-3 can reach scanning depths of up to 7 meters (approx. 23 feet) depending on soil composition and target size.
• Real-Time 3D Visualization: Sync smoothly via Bluetooth to the custom 3D analysis app for Android and iOS. Instantly analyze target depth, size, and shape with intuitive color-coded graphics that separate magnetic metals (like iron) from non-magnetic treasures (like gold, silver, and copper).
• 4 Advanced Scanning Modes: Fully adaptable to any search scenario with Automatic Ground Scanning, Manual Ground Scanning, Live Scan (for quick unbound target tracking), and a precise Pinpointer function.
• Multi-Terrain Performance: Engineered to deliver stable, high-resolution data across various challenging ground conditions, whether you are scanning sandy beaches, rocky hillsides, or dense clay soil.
