 Groundtech GR-4 Dual

The Groundtech GR-4 Dual is the next-generation professional 3D ground scanning and metal detection system designed for treasure hunters, archaeologists, and geophysical researchers.
This dual-technology device combines MFS-2 Dual Sensor 3D scanning with an integrated Pulse Induction (PI) detector, allowing for precise detection of metals, cavities, tunnels, and other underground structures up to a depth of 15 meters.

Its compact design, advanced processing unit, and interactive touchscreen display provide real-time 3D visualization and accurate analysis of subsurface targets. The GR-4 Dual delivers unmatched accuracy, speed, and ease of use in all soil conditions, including highly mineralized or saline grounds.
