The periodic magnetic field generated by the underground treasure detector generates an eddy current electric field in space. If the eddy current electric field encounters metal, eddy currents are formed and can be detected. The eddy currents react to the magnetic field, changing the voltage and impedance of the coil.

The periodic magnetic field generated by the underground treasure detector generates an eddy current electric field in space. If the eddy current electric field encounters metal, eddy currents are formed and can be detected. The eddy currents react to the magnetic field, changing the voltage and impedance of the coil. The current in the transmitting coil generates an electromagnetic field, just as an electric motor also generates an electromagnetic field. The polarity of the magnetic field is perpendicular to the plane of the coil. Whenever the current changes direction, the polarity of the magnetic field changes. This means that if the coil is parallel to the ground, the direction of the magnetic field will alternate, one moment perpendicular to the ground downward, the other moment perpendicular to the ground upward.

As the direction of the subsurface magnetic field changes repeatedly, it will interact with any conductor target it encounters, causing the target itself to produce a weak magnetic field. The polarity of the target magnetic field is exactly opposite to the polarity of the transmitting coil. If the magnetic field generated by the transmitting coil is perpendicular to the ground downward, the target magnetic field is perpendicular to the ground upward.

The frequency of this current oscillation is the same as the frequency of the target magnetic field. The receiving coil amplifies the frequency and transmits it to the console of the underground treasure detector, which then analyzes the signal.

Most professional treasure detectors are new products made with advanced technology and foreign components. Compared with other types of products, the treasure detector has the characteristics of wide detection depth, accurate positioning, strong resolution, energy saving and environmental protection, and long service life. It is mainly used to detect buried metal artifacts and gold and silver treasures. Since the gold detector entered various fields, there have been treasure hunters to detect ancient coins, gold and silver, thus embarking on the road to wealth. The treasure detector is a professional product. In the eyes of Aibao people, they are more willing to pay a price that the layman cannot accept for a good yellow treasure detector. In the process of purchasing the yellow treasure hunter, many laymen or novice treasure hunters often consult and question the function and efficacy of the yellow treasure hunter. They don't want to spend too much money to buy a suitable treasure detector. On the contrary, in order to save money, they bought some low-end and inferior products. In the end, we often spend more money, but fail to achieve satisfactory test results, and finally get nothing.

A good treasure detector must have its value. If the gold detector you buy does not meet your needs well, or you are not satisfied during use, you may miss the opportunity to explore the treasure and reduce the possibility of the treasure being discovered.
