Application: Electrical Resistivity Tomography (ERT) is a geophysical method widely used for applications such as groundwater exploration, landslide investigations, environmental studies, and infrastructure assessment. The technique helps in identifying subsurface structures, variations in soil and rock properties, and detecting potential hazards. Spectations: Model: SYSCAL Junior / R1Plus  Depth of Investigation: Up to 50 m Electrode Spacing: 5 m Types of Survey:  2D and 3D Resistivity Imaging
