Ruggtdized multifunction V6 system was introduced by Institute of Geology and Geophysics, Chinese Academy of Sciences from Canada Phoenix Geophysics Limited in 2000. It is one of the most powerful instruments for controlled source audio-frequency magneto-telluric exploration. It has 62 frequency series, Strong transmittal power and strong ability of anti-noise (anti-interference). It also has fast 512kHz 16-bit ADC plus minimum 8 gain bits for controlled source. The transmitter and recever are synchronized with GPS. These feature makes it has advantage of monitoring much weak effective with high vertical and horizontal resolution and high ratio of signal noise. Hence it can be used to make high precise exploration. Case studies in standart geological profile near Niulanshan water power station and in Laiwu iron mine shandon province with V6 system show that V6 system can carectly determin the depth of objective layer and the distribution and structures of water bearing stratum.
