Zonge International was the first to recognize the potential of micro-processor controlled receivers and was the first to commercialize it in 1977 with the GDP-12. Continuous development of the receiver and transmitter systems have resulted in adaptation of these tools to numerous applications. Zonge receivers and transmitters are the most versatile electrical and EM receivers available in the world today. Zonge also manufactures a complete line of supporting instruments and ancillary equipment required in systems used for the acquisition of most electrical resistivity and electromagnetic survey data.

These tools are summarized in our Equipment Brochure. [Specs PDF:6768k]
