Deviation information is valuable in mine planning and subsurface mapping. The gyroscopic device is used for measuring deviation through steel drilling rods or casings and in open holes where magnetic rocks occur. The digital solid state design uses a continuous reading gyroscope (modified Goodrich, or WellNav), with information recorded at operator selectable sample intervals. It is not necessary to stop to take station data. Natural Gamma and Magnetic Azimuth are optional. All software to process survey data (including drift corrections) is included in the Log and Display programs which is included with the System VI logging system.
