Underwater recorders and multi-hydrophone buoys for oil and gas exploration

RTsys helps oil & gas companies to make their prospecting campaigns. The use of airgun is common for oil & gas prospection. This is pretty heavy and we provide these companies tools to determine how the noise generated can affect the marine wildlife.
