SQ-5 Dual-frequency Portable Intensification-polarization Instrument

GEOSUN Best selling useful gold metal detector equipment

                                                                              ——Applicable to different terrain minerals, water resources rapid census

                                                                              ——35 years of technical precipitation and promotion


Dual-frequency electrochemical device and its technical methods have independent intellectual property rights, won the "National Science and Technology Progress Award", "National Invention Third Prize", "National Invention Exhibition (Beijing) Silver Award" and other awards. During 35 years, the instrument has been updated for 6 times, and has been widely used in the field  prospecting team all over the country, it has detected a big lot of  mineral sources including gold, silver, copper, lead, zinc, antimony, ect.  According to the authority of incomplete statistics in 2013, dual-frequency IP instrument helped the field prospecting team to find and achieve direct economic benefits of more than 40 billion yuan, and ascertain potential exploitable resources worth more than 200 billion yuan. The instruments have been also successfully applied in Indonesia, Cambodia, Malaysia, India, Iran, Saudi Arabia, Australia, Russia, Bolivia, Peru, Chile and other countries.
