GDP-32II geophysical data processor is actually a million used,
multi-channel receiver, designed to collect any type of
electromagnetic field or data, the bandwidth of DC (DC) -8 kHz.
GDP-32II the design, accumulated from the previous GDP-12, GDP-16,
GDP-32 has 25 development experience. The design emphasized the
flexibility of software, the best data quality and poor field
conditions of the solid.
