With the continuous development of science and technology, the reaction to the metal detector research and development and production, so that it has a very high detection capability, Underground Metal Detector has now been able to seize a small metal objects, expanding its application areas.
1, the world's first metal detection equipment was born in 1960. In the past 50 years the metal detection equipment has experienced several generations of detection technology changes, from the initial analog signal technology to continuous wave technology. Until now, the use of balance coil technology, metal detector`s simple magnetic field cutting principle adopt a variety of scientific and technological achievements. In terms of sensitivity, resolution, detection accuracy or performance have a qualitative leap.
2, the most widely used field of metal detectors is to explore buried in the underground valuable metal objects, the use of the environment is generally in the wilderness or indoors, through metal detectors continue to scan the ground to find valuable metal targets, such as hidden In the underground gold and silver treasures, historical monuments, and other scrap metal materials. And the treasure hunter is also gradually being recognized and accepted, and more and more applications in all areas of social life.
3, domestic and foreign treasure hunters have formed a professional industry. With the advancement of electronic technology, treasure detectors made a rapid development from the tubes, transistors and even integrated circuits. This area also assembled a large number of advanced technology research and development staff, so that treasure hunters continue to introduce new technology.
