All Metal Mode – Search mode ” all metal “
Search mode ” all metal “ as a general rule it is one of the few settings available in most metal detectors. The purpose of this mode – scanning without discrimination of absolutely all types of metals (iron, zinc, various alloys , bronze , copper , gold, silver, platinum , etc.) – which allows for a small increase in depth.
Typically, this feature is useful in the exploration area ( for example for that would locate the place where stood the old homestead ), and accompanied by frequent analysis of excavated objects. When searching for ancient coins with a metal detector , some search engines use disriminatsii mode .
This option is more widely used with some types of search coils , for example the type of metal separation is slightly better in katshek working technology Double-D, and in some cases, when the search space is very large signals concentration in the soil with a large reel diameter can simultaneously meshing several objectives of different metals (e.g. iron and copper coin and nail at a time) that causes protivorichivaya indicators respectively , in such circumstances the contrary assist coil with a small diameter , oval shape, not more than 9 inches.
One has only to add that of course mode ” all metal ” will be noisier than the search mode when discrimination is cut only iron (at least) , and each iron metal detector will react to certain sounds (usually the lowest audible tone is allocated for signaling only iron ) , instead of what would keep silent on an iron nail as it would be in the mode of discrimination. But ! Search with the settings and alerts for all metals (even iron ) first informatively more – even if you have more and listen to the instrument , but believe me , after a week you ‘re not going to ignore these complexities and your professionalism will increase drastically .
Also, if you ‘re looking for ancient Villages example , of course , such places are very rich in ancient finds extremely valuable , but the concentration of color signals in such places is much less than the iron – and that the iron or scraper easier to stumble in the exploration of the next hill and identify that in this place and then proceed to explore the area thoroughly with a metal detector . But every excavated color signal in such a place would be very unique – it or ancient coin , or decoration ( dinning pendant, bell ), etc.
Now imagine what would be the chance to locate such a place if your detector has been disabled notification railway purposes. Similarly, in an empty field tested for iron targets , digging them from time to time , where there was a building ( manor house , mill, farm , homestead , etc.) – a lot of value here forged – this is the first signal that is worth taking into attention .
