Metal detectors  Their variety and purpose

Metal detector – a device designed to detect metal objects in a variety of environments, such as land, water , deep space , construction projects or personal searches . Before you select the device you must decide what kind of substance and the environment in which it will be searched .
Through constant research and development work , these devices have become indispensable in the industry of metal detection . Today, metal detectors are widely used in various spheres of life.

Metal detectors can be divided into several groups:

Simple ground metal detectors . Have a small set of features in the search. Depth of detection of such devices is small and depends on the soil.

Semi metal detectors . These devices are used by people who have enough experience in the search. In principle, the development of such devices is the use of multi-frequency radiation. They are able to operate not only audio but also visual information. That is displayed , where you can see the code image of the detected object and determine its quality.

Professional underground metal detectors . Have polyphonic alert , multi-frequency range of the search , a lot of manual and automatic settings .
Do these devices have the ability to determine the presence of “color ” of the object next to the “black” with sufficient accuracy . This allows you to refine your search on the ground, where many domestic iron trash . Professional metal detecting when a signal is visual , digital and audible alarm . The analysis of these readings and gives the seeker the opportunity to understand what he found , the depth , size . Depth of detection of relatively large objects can reach 150 – 200 cm

Underwater metal detectors . The settings in these devices are designed in order to take into account the interference caused by water. In this case, in both fresh and salt water in different interference . Underwater detectors used to find at the bottom of the reservoir, on the beaches , in the coastal zone. They have a sealed case , headphones, and a lot of settings for search in different situations. Visually, they do not give out the information, only the audio . Depth of detection of such devices depends entirely on the search environment .

Deep metal detectors – this is a serious search engine technology . Depending on the model, define objects to a depth of 6 meters. For example, pipes of large amounts of metallic structures . But here you can find some disadvantages . So, they are designed for the detection of volumetric objects at depth and can not find a subject that is very close to the surface. Such devices are widely used in engineering services, maintenance of underground utilities . With these experts can determine the nearest centimeter , where the object is located, which direction it lies , and more.

Arched , or framework , metal detectors . Permanently installed and are used to detect metal objects crossing beyond man. Arched metal detectors can be seen in airports , railway stations and crowded during the stock. Today , the settings of these devices can detect a metal object the size of the eye pin. They are designed to monitor and verify the presence of a cold or firearms and explosives among the large flows of people.

Hand-held metal detectors Inspection – instruments for the detection of metal objects in the body search . Widely used in the security MVD, FSB , customs, military and security services. Metal detection device should be moved so that the scanning surface is more fully cover all areas of the test object . Detection is performed at a short distance from the object inspection.
