Profile: Advanced Geosciences, Inc. manufactures high-resolution geophysical instruments for resistivity and IP imaging. We manufacture the SuperSting R8/IP, SuperSting R1/IP & MiniSting earth resistivity imaging systems, and the EarthImager 2D & 3D inversion software for processing of recorded data. The SuperSting R8/IP multi-channel resistivity imaging system is an 8-channel instrument for simultaneous data acquisition. It reduces the number of reading cycles by 8. The SuperSting R1/IP single channel resistivity instrument can be used for automatic resistivity and IP imaging. It has a set of stored command files for different electrode arrays, and can be programmed to perform any type of resistivity/IP survey automatically.
