Ywhere, including lawns, beach, mountains and so on. The detector is versatile and easy to use, you also can share this product with your friends or familys. Come on and try it.100% Brand new and high quality. Come on and try it, it will not let you down. You can use it for deeper underground. For three different metal categroies, which can give you a better using experience. For you to choose: the stereo.
And mono headphone, the output vol-ume of the loud speaker or headphone can be adjusted. Height of metal detector can be. So it suitable for people of different heights to use. The detector can be set to not respond to certain objects during the detection process.Whether he's just beginning to dig for gold detection or has mastered the metal detector, this gift is sure to make him happy. 6F22 9V alkaline battery (NOT included). 290 185mm / 11.42 7.28in.

E 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 detected metal.
Generally speaking, the larger the area, the greater the number, and the greater the corresponding detection depth; conversely, the larger the area. The smaller the number, the smaller the corresponding depth. The depth marked by the instrument is the maximum depth that can be achieved under good conditions according to the industrial standard of the product.The depth of detection will be different under different soil conditions. For example, if the soil is wet or dense, it will be weaker for gold detection. Therefore, it reduces the detection depth of the instrument. In addition, the detection depth will be attenuated when the battery is low and the transmission power is insufficient. In this case, please replace the battery in time. Get a good detection effect?
The detection effect will be achieved 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, causing metal rust to spread around and react with the surrounding soil, generating a stronger magnetic field, increasing the area of the metal and increasing the strength of the signal.
The longer the time, the greater the signal strength, and the deeper the detection depth. Q: What aspects should be paid attention to in the maintenance of the instrument? Do not detect in rainy days, because the instrument itself does not have a waterproof function.
If water enters the circuit board, it may cause a short circuit or other failures. Remove the battery when not in use, because the battery may corrode the circuit board due to liquid leakage if it is placed in the instrument for a long time.
Please keep it in a dry place when not in use for a long time. An underground metal detectors 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 geological characteristics. Therefore, the detection depth of underground metal detectors cannot be detected in the air (that is, suspended in the air). The best detection effect can be. Chieved when the metal detector and the earth have a magnetic induction balance. Hanging in the air cannot achieve the magnetic induction balance!
For example, if a silver dollar can be detected at a position of 20 cm in the air, if the silver dollar is buried underground, the detection depth will be greatly increased, and the older the buried, the easier it is to detect, because the metal is buried for a long time The underground will gradually oxidize, resulting in metal rust spreading around and reacting with the surrounding soil, generating a stronger magnetic field, increasing the area of the metal and increasing the strength of the signal.
