Magnetic anomalies
Magnetic anomalies in the ground indicate the presence of hidden metallic objects such as ferrous debris, infrastructure components, or unexploded ordnance. FOERSTER detection systems identify these anomalies with high precision using active electromagnetic induction or passive magnetometer technology.
Subsurface metallic objects distort the Earth’s magnetic field in measurable ways. FOERSTER systems detect and analyze these magnetic variations to locate buried structures or objects safely and efficiently. Active electromagnetic induction (EMI) methods are ideal for near-surface targets, while passive fluxgate magnetometers enable detection at greater depths. Depending on the survey type and terrain, FOERSTER technologies can be used in handheld mode, integrated into mobile carrier systems, or deployed on multi-probe platforms for large-area scanning. Combined with powerful data evaluation software, these systems deliver precise georeferenced maps of magnetic anomalies – providing valuable information for clearance operations, environmental surveys, and archaeological research.
