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.

For products in many industries and fields, the precision of metal detection has an important impact on quality assurance, but the precision of metal detector equipment is affected by many factors. How to conduct more accurate detection of metal detector?

In order to be able to detect metal impurities more accurately, the current metal detection equipment has a high sensitivity, but some users in the use of sensitivity error, metal detector in the use of the process of sensitivity is not up to the standard, what is the reason?

To detect whether there is metal around, we can use the metal detector to help us detect. Once the instrument detects the metal, it will start the alarm. When working, we need to pay attention to the following points:
