Combined system 16SG Series

What makes this system really unique is its extreme versatility. Our design philosophy for this realization was in fact characterized by the need to create a system which would not only guarantee important performances and make it easy to use, but which would really be of multipurpose type. The possibility to manage the two different investigation methods – refraction/reflection seismics as well as electrical imaging – through a high-level softwa-re and a hardware characterized by extraordinary performance features, has allowed the realization of a combined modular instrument, which may grow in successive steps, finally offering the opportunity to complete your system base as to your real needs
