Underground metal detectors, as a necessary part of treasure hunters, have increasingly entered people's lives. Treasure hunting has become a profession and hobby that people increasingly yearn for. The presence of detectors does not mean that treasures can be found. There are many skills in using underground metal detectors. These skills will help you save a lot of trouble, increase the operability of the instrument, and enable you to buy detectors too quickly. Having some experience in metal detection can have a very good auxiliary role in metal detection, and increase the accuracy of metal detection by metal detectors. In daily detection, the most common problem is the judgment of true and false signals. Next, I will give you a brief introduction of a good way to distinguish the true detector from the false detector.
Firstly, the signals emitted by metal detectors are divided into two kinds: true signal and false signal. True signal refers to the signal sound caused by the detection of metal, while "false" signal refers to the signal caused by minerals, etc. False signal will interfere with our judgment, so we need to shield the false signal by adjusting metal detectors. Today's metal detectors basically have the function of adjusting the balance, which is to remove false signals, so as to better eliminate interference (this is the ability to resist mineralization). The detector with good performance has stronger prospecting and mineralization ability.
Secondly, before the exploration area starts to work, we must fully understand some geological conditions in the area, such as geology, geomorphology, electronic interference and so on, to understand that these can remove certain false signals.
Then for the detected object, repetitive detection is needed, so that the result can be more accurate.
Finally, in the process of detecting underground metals, all kinds of underground conditions are very complex and changeable. We should proceed from reality, repeatedly verify and analyze, without perfect instruments, all instruments should be people-oriented, so different people will use the same instruments to produce different effects. It is necessary to respect the scientificity of the instrument and make multi-directional judgment and analysis based on geological composition, exploration experience and other data.
