Q: why can't we reach the depth of the instrument sometimes? A: the detection depth of all metal detection instruments is closely related to the area, shape and weight of the metal to be detected. Generally speaking, the larger the area, the more the quantity, the greater the corresponding detection depth; On the contrary, the smaller the area is, the less the quantity is, and the smaller the corresponding depth is.
The depth marked by the instrument is as deep as it can be in good condition according to the industrial standard of the product. The detection depth will be different under different soil conditions. For example, the signal strength of the detected metal will be weakened in the case of wet soil or high density, so as to reduce the detection depth of the instrument. In addition, when the power is low and the transmitting power is insufficient, the detection depth will be attenuated. In this case, please replace the battery in time.
Q: how to get good detection results? A: the detection effect will be made when the soil is dry or the metal is buried in a long time. The farther the metal is buried, the deeper the detection depth is. Because the metal buried in the ground for a long time will gradually oxidize, resulting in the diffusion of metal rust around, reacting with the surrounding soil, producing a strong magnetic field, increasing the area of the metal and increasing the intensity of the signal. The longer the time, the greater the signal strength and the deeper the detection depth! Q: what should be paid attention to in the maintenance of the instrument? A: don't detect in rainy days, because the instrument itself has no waterproof function. If the circuit board is flooded, it may cause short circuit or other faults.Remove the battery when not in use, because if the battery is placed in the instrument for a long time, it may corrode the circuit board due to liquid leakage. Keep in a dry place when not in use for a long time. Q: how deep can underground metal detectors probe? A: the detection depth of the underground metal detector is related to the metal material and shape of the object to be detected and the soil quality of the detection site. 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, the detection depth of the underground metal detector can not be detected in the air (that is, suspended), Only when the metal detector and the earth have a magnetic induction balance, can the detection effect be better. Hanging in the air can not achieve the magnetic induction balance! For example, if a silver coin can be detected at a height of 20 cm, if the silver coin is buried underground, the detection depth will be greatly increased, and the longer it is buried, the easier it will be detected, because the metal will gradually oxidize when it is buried underground for a long time, causing metal rust to diffuse around, react with the surrounding soil, and generate a strong magnetic field, Increase the area of the metal, but also increase the strength of the signal.
