Groundtech GR4 Dual: Discover What Lies Beneath with Cotyora Detector
The Groundtech GR4 Dual is a revolutionary technology for treasure hunters, archaeologists, and engineers, setting a new standard in the world of underground imaging. Offered with the assurance of Cotyora Detector, this device combines advanced 3D imaging technology with a powerful Pulse Induction (PI) detector system in a single, sleek body.
Designed for professionals seeking maximum efficiency in all terrain conditions, the GR4 Dual provides high-precision detection of buried metals, chamber tombs, tunnels, and underground voids.
Professional 3D Underground Imaging & Gradiometer Technology
At the heart of the Groundtech GR4 Dual lies the MFS-2 dual-sensor gradiometer system (±2000 µT). This cutting-edge technology analyzes magnetic field variations beneath the surface with millimetric precision, providing you with the most accurate data possible.
Built-in Scanning Modes:
3D Ground Scan: Create high-resolution three-dimensional maps of the subsurface.
Live Scan: View real-time data streams while on the move.
Pinpointer: Precisely locate the exact center of your target.
Quick & Advanced Detector Scan: Specialized modes for metal discrimination and depth analysis.
Feel the Power of Depth with Pulse Induction (PI) Technology
Unlike conventional detectors, the GR4 Dual features an integrated Pulse Induction (PI) system operating at a 1 kHz frequency. This system allows for interference-free operation even in soils with high mineral content.
Feature
Detection Depth
Detector System (PI)
Up to 3 Meters
3D Scanning System
Up to 15 Meters
As Cotyora Detector, we highly recommend this device for its exceptional stability in salty soils, highly mineralized ground, and coastal regions. Large metal masses and void structures that standard detectors often miss are clear and reachable targets for the GR4 Dual.
Built-in Display & Standalone Operation
Unlike many underground imaging devices that require an external tablet or phone, the Groundtech GR4 Dual can operate independently. The high-resolution color display integrated into the device allows you to view all data instantly.
Processing Power: 240 MHz CPU for rapid data processing.
Connectivity: Bluetooth 4.2 BLE and Type-C fast charging support.
Battery Life: 3.7V Li-ion battery providing 10 hours in 3D mode and 6 hours in PI mode.
4D Analysis with the G-PORTAL Mobile App
The GR4 Dual, available through Cotyora Detector, does more than just collect data; it transforms it into insights. With the Android and iOS compatible G-PORTAL application, you can:
Analyze data in 3D and 4D detail.
Generate reports with 25-language support.
Archive past scans and plan your excavation strategy from your office.
