Metal Clay
Ground detectors – the universal instruments of varying complexity for a variety of search terms. They apply the latest technology, you can customize the metal detector at the right kind of metal and effectively filter out extraneous signals from metal objects. Do metal detectors are set for the soil with varying degrees of mineralization and a strong metallic debris debris. For beginners There are metal detectors with simplified settings. Experienced users will approach the universal instruments that will take into account any details of the search. There are also specialized metal detectors – to search for great depth, in highly saline soil, under water.
Metal for Beginners have a lot of features in the search, the cost ranges from 100 to $ 500. To detect the target more often use the same frequency, at least two. Include discrimination, sometimes the definition of the depth of the target. Depth of detection of metal detectors is small and depends on the ground, "flakes" (coins 15-17 cc) – 3.5 cm, five cents of Catherine II – 15-20 cm, ax – 20-30 cm, cover from the hatch – 70 cm. Some craftsmen are found in the literature schemes of metal detectors and instruments collect yourself. But the quality of such a detector could be better. At home, almost impossible rebuild the detector from various electromagnetic "interference", even in the presence of special equipment. Background generated by the surrounding metal objects, creates a lot of noise. As a result, when tested on the ground, where there is no such background, the detector starts to give incorrect readings.
