Electromagnetic induction locator

2012_8Mapping of buried utilities and electrical line in order to avoid the occurrence of accidents and damages during the execution drilling research. Since the investigated land was located in an industrial site, the presence of numerous metalic elements made it impossible to use electromagnetic equipment in time domain and vertical magnetic gradient method. Georadar (GPR) method was also impossible to use because of the land deformation, boulders layer and gravel surface; all these prevent coherent  and interpretable signal reception. Under these condition we used only electromagnetic induction locator with different frequencies signal. The result  were very good and penetration of passive and active cables or pipelines were avoided.
