The Groundtech A2 Geo combines 3D ground scanning, pulse-induction metal detection and geo-electric resistivity in one system. Use the functions for different survey questions and interpret readings in light of site geology and the selected mode.
Key Highlights: • 3D ground scanning and metal detector functions for different underground targets. • Automatic and manual resistivity modes for groundwater detection surveys. • Groundtech app support for reviewing survey data on a compatible device. • Rechargeable field unit; confirm the supplied accessories and software package before ordering.Groundtech A2 Geo 3D Ground Scanner, Metal Detector and Groundwater Locator
The Groundtech A2 Geo combines 3D ground scanning, metal detection and groundwater survey functions. Each system measures different features, so match the method and interpretation to the survey question.
The Groundtech A2 Geo pairs magnetic survey data with geo-electric resistivity. Use the ground scanner for subsurface anomalies and the groundwater function to examine differences in soil resistance.
A2 Geo Ground Scanning and Groundwater Detection Applications
The Groundtech A2 Geo 3D Ground Scanner, Metal Detector and Groundwater Locator adds geo-electric resistivity to the A2 scanning platform. Its metal detector and 3D ground scanner functions cover buried metal and magnetic anomalies, while groundwater detection requires a separate resistivity survey and careful interpretation.
By integrating two of the most powerful detection methods—3D Magnetic Ground Scanning and Geo-Electric Resistivity—into a single, robust device, it becomes the ultimate tool for deep archaeological mapping, precise water detection, and locating large subterranean voids or non-magnetic precious metal caches.
A2 Geo Ground Scanner and Groundwater Locator Technologies
A2 Geo MFS-3 3D Ground Scanner
The Groundtech A2 Geo MFS-3 dual sensor supports 3D surveys of magnetic and other subsurface anomalies. The manufacturer states up to 20 metres depending on soil and target size; app images alone cannot prove a target’s identity.
A2 Geo Geo-Electric Groundwater Detection
The Groundtech A2 Geo geo-electric system measures resistivity across a four-line survey. Interpret groundwater indications against geology and field evidence; a reading cannot guarantee a productive well or identify every void.
A2 Geo Ground Scanner and Metal Detector Modes
- 3D Ground Scanning
Systematically map the underground terrain. The device records data point-by-point, translating variations in the magnetic field into a 3D model that reveals target shape, exact depth, and dimensions up to 20m. - Automatic Resistivity
Designed for ease of use. Hammer the 4 probes into the ground, and the ground scanner’s processor automatically calculates the complex resistance formulas, instantly indicating the presence of water or voids on the screen. - Manual Resistivity
Built for experienced geologists and engineers. This mode allows the operator to manually select the active probes and customize the scanning parameters for highly specific localized measurements. - Live Scan & Pinpointer
Need a quick check before excavating? The Live Scan mode provides real-time, instantaneous feedback of what is directly beneath the MFS-3 sensor, perfect for rapid area surveying.
A2 Geo 3D Ground Scanning Analysis Software
The hardware is only half the equation. The 3D ground scanner transmits all gathered data via high-speed Bluetooth 4.2 directly to the included tablet or your smartphone. Utilizing the proprietary Conrad 3D Analysis App (G-Portal compatible), users can rotate, zoom, and dissect the scanned data in full 3D color. The software automatically applies color-coding filters (e.g., Red for dense metals, Blue for cavities/water, Green for neutral soil) making interpretation intuitive and precise.
