The Groundtech GR-4 Dual is the ultimate hybrid detection system, merging two professional-grade technologies into one advanced platform — the MFS-2 Dual Sensor for 3D imaging and an integrated Pulse Induction (PI) module for deep metal detection.
With this combination, users can locate treasures, gold deposits, voids, and hidden structures up to 15 meters deep in 3D mode, while the PI system enables metal detection down to 3 meters, even in mineralized or rocky soils where traditional detectors struggle.
The GR-4 Dual supports several scan modes — 3D Ground Scan, Live Scan, Pinpointer, and Detector Quick Scan — ensuring flexibility for all exploration conditions. Thanks to its 240 MHz processor, Bluetooth connectivity, and multilingual software, the GR-4 Dual delivers high-speed data analysis with crystal-clear visual results via the Groundtech app.
Powered by a 3.7 V Li-ion rechargeable battery, the device runs for up to 10 hours in 3D mode and 6 hours in PI mode. Built for professional treasure hunters and geophysical researchers, the GR-4 Dual is a true all-in-one detection solution that redefines performance, depth, and reliability.
