Fugro Airborne Surveys has been a leader in helicopter-borne electromagnetic surveying for over 30 years. They are committed to extensive research and development to continuously improve their DIGHEM V system, which is the most advanced electromagnetic survey tool. The DIGHEM V system offers unique characteristics like separation between transmitting and receiving coils, the widest range of frequencies, and an integrated magnetometer. This provides benefits like higher resolution data and a complete geophysical survey from the air. The system has applications in mapping saltwater intrusion, geothermal zones, aquifers, coastal bathymetry, and locating minerals.
