Electromagnetic (EM) Surveys
DGI uses Schonstedt instruments to locate and trace buried ferrous metal objects (e.g. asphalt covered manhole covers, pipes and drums). In addition, we use GPR and Split Box technology to locate these objects. We are looking toward purchasing an EM61 for more broad-scale magnetic anomaly surveys.
