1. What are the types of underground detectors at present?

At present, there are many kinds of underground detectors, such as home-made ones, imported ones, probing disc ones, wide-range searching and scanning ones, visual imaging ones, pulse ones and so on.

2. What is the price of the underground detector?

Due to the advantages of different types of underground detectors, the price (from several hundred yuan to several hundred thousand yuan) and performance of different types of underground detectors also vary greatly. Customers all want to buy the best underground detector, even if it costs hundreds of thousands of dollars, but I think it is not desirable, the most important thing is to choose a function and price most suitable for their own use, so that it will be the best.

Three, how to choose suitable for their own underground metal detector?

Many customers are so cheap that they buy underground detectors that don't meet their requirements, which is a waste of money. There are also a lot of people pursue high-performance machines, amateur use of a lot of functions can not be used, they feel no interest, this is also a waste of money. The following is some practical experience, I hope to have a general understanding of how customers choose suitable underground detectors for their own use. Such as:

(1) Purchase of economical and practical underground detector (1000-2000 yuan)

If you just use it to detect scrap metal in waste sites and demolition sites, then you only need to buy an underground detector that costs about 1,000 yuan. Under normal circumstances, you can choose to buy a maximum detection depth of 1.5 to 5 meters of underground detectors, the first is cheap, the second is the depth is sufficient. In general, the metal on the waste site will not be buried very deep, and the use of these machines can be easily detected out of the waste metal. Newspapers and the Internet also often reported that many people use these underground detectors to detect scrap metal in the demolition site. Generally, the metal detected by one person can be sold for more than 100 yuan a day under good conditions. In this case, you only need to use it for half a month or so to earn back the money of the machine. It's cheap, so if you're primarily detecting scrap metal, these underground detectors are a good option.

(2) Purchase of practical underground detector for treasure exploration (1000-5000 yuan)

If you're looking for ancestral gold, antiquities, copper coins, silver dollars and other treasures, you should buy a better, deeper underground detector. If you are not sure how big the object is or the approximate volume and depth of the burial, you need to make a maximum depth estimate and buy an underground detector that is deep enough. For example, your target is 20 x 20 cm in size, and is probably buried in 2 to 3 meters and has been buried for a certain number of years. In this case to buy 5 ~ 10 meters of underground detector to meet the requirements, and the current price is more affordable.

(3) Purchase of high-performance underground detector (more than 5000 yuan)

If all the above does not meet your requirements, then it is recommended that you buy some high performance products. Have can estimate the object size and depth of underground detector (products such as the United States imported GTI2500 model), a wide range of search type underground detector (the United States imported VR series product and so on), visual imaging of underground detector (the USA imager, Turkish gold king imager), but the prices of these products are expensive, start at tens of thousands of, many hundreds of thousands of, Buy this kind of instrument is the basic dry industry to make money, the general amateur look for the house before and after the grandparents buried things do not need to buy such a situation.

IV. Suggestions:

Buy a suitable for their own use of hitting a treasure instrument can help you better detect valuable items, for the moment whether detection scrap metal or grandparents relic, is a very good detection tools, and the buried items whether it is a wooden box or pottery jar containers do not affect detection performance, scattered items is easy to detect more than one place alone.
