Geovizer – Compact multifunctional electromagnetic profiler (EM-I)

The Geovizer is a compact multifunctional electromagnetic profiler (EM-I), designed for fast, accurate, contactless subsurface detection. Based on the multi-frequency electromagnetic induction method, this geophysical equipment analyzes the apparent resistivity of soils and locates anomalies down to 3 meters depth.

Thanks to its high performance, the Geovizer provides detailed spatial mapping of the soil’s secondary signal, facilitating the identification of high electromagnetic contrast targets such as:

• metallic objects and structures,

• underground cavities and voids,

• areas saturated with highly mineralized water,

• pipelines, tunnels and bunkers with wet walls.

It is particularly effective for detecting high conductivity objects in low soil conductivity environments, making it a reference tool for engineering, environmental and security applications.

Technology and key features

The Geovizer tri-frequency EM-I profiler operates on three selectable fixed frequencies in the 12.5 to 111 kHz range, enabling optimal adaptation to field conditions and survey objectives.
Each measurement point is automatically georeferenced through GPS coordinate integration.
