Our firm offers geophysical services and I am often asked if we complete ground geophysics in-house, which I find very curious. Perhaps explorers are under such pressure to get their surveys done ASAP, that requesting the firm that does the surveys in the field to interpret the data appears to be efficient. My worry is that going this route does not put in enough thought about how that survey is designed, who the best service provider is, if sufficient quality control was completed and how the data is interpreted.
