Countries Terraquest Has Surveyed In Better Data Better Results Our Structural Multi-View Airborne Geophysical Surveying System combines Magnetics, Radiometrics and our advanced, proprietary XDS VLF-EM technology in a low level helicopter platform to map detailed geological structure. The system is unique in that it is an all inclusive mapping tool housed in one lightweight, portable package. The system is designed to attach directly to the undercarriage of the helicopter via standard attachment points and operates from existing aircraft power. The radiometric crystal pack fits into the luggage compartment while the data acquisition system fits on a passenger seat in a portable case easily accessible to the operator. The potential field sensors are housed in the tip of the stinger itself, providing a 16' separation from the aircraft. The portable system is ideal for surveying of property sized projects in rugged terrain, in remote areas, typically at 30-50 meters terrain clearance. more... See more text
