GT500A Geological Water Detector
The GT500A is an advanced multi-channel underground water detection instrument designed for borehole planning, groundwater exploration, geological mapping, and structural surveying. Using natural electric field frequency selection technology and simultaneous multi-frequency data acquisition, it delivers highly accurate results for locating water sources, geological faults, karst caves, mined-out areas, and subsurface anomalies. With real-time automatic mapping and intelligent anomaly analysis, it significantly improves exploration efficiency and decision-making accuracy in the field.
