1. Why sometimes the depth indicated by the instrument cannot be reached in the actual detection?
The detection depth of all metal detection instruments has a great relationship with the area, shape and weight of the metal to be detected. The larger the area and the more quantity, the greater the corresponding detection depth; On the other hand, the smaller the number, the smaller the corresponding depth will be. The depth indicated by the instrument is the maximum depth that can be achieved under optimal conditions according to the industry standard of the product. The detection depth will be different under different soil conditions. For example, if the soil is wet or dense, the signal strength of the metal to be detected will be weakened and the detection depth of the instrument will be reduced. In addition, the detection depth will also be attenuated when the battery is low and the transmit power is insufficient. In this case, please replace the battery in time.
2. How to get the best detection effect?
The detection effect will be improved when the soil is dry, or the metal is buried in a long time. The older the metal is buried, the deeper the detection depth. Because the metal is buried in the ground for a long time, it will gradually oxidize, and the metal rust will spread to the surrounding and react with the surrounding soil, resulting in a strong magnetic field, which increases the area of the metal and increases the strength of the signal. The longer the metal buried under ground, the stronger
the signal strength, and the deeper the detection depth will be!
3. What aspects should be paid attention to in the maintenance of the instrument?
Do not detect in rainy days, because the instrument itself has no waterproof function, and if the circuit board enters water, it may cause short circuit or other failures. Remove the battery when not in use, as the battery may leak and corrode the circuit
board if left in the instrument for a long time. Please store in a dry place when not in use for a long time.
4. How deep can an underground metal detector go?
The detection depth of the underground metal detector is related to the metal material, shape and soil quality of the detected object. The detection depth of the same detector in different regions is completely different, because the underground metal detector is designed according to the geological characteristics. Therefore, in the air (that is, in the air), the detection depth of the underground metal detector cannot be detected. The best detection effect is achieved when the metal detector and the earth have a magnetic induction balance. The magnetic induction balance cannot be achieved in the air! For example: A silver dollar can be detected at 20 cm in the air, if the silver dollar is buried underground, the detection depth will be greatly
increased, and the longer the burial age, the easier it will be to detect, because the metal is buried for a long time. The underground will gradually oxidize, and the metal rust will spread to the surrounding and react with the surrounding soil, generating a strong magnetic field, increasing the area of the metal and increasing the strength of the signal.
