Metal detectors with discriminator
prices on 43 models— the discriminator allows the metal detector to recognize, with a certain degree of accuracy, what metal the found object is made of, without digging it out. Usually, this function allows you to filter the finds by materials so that the metal detector does not react at all to useless debris such as bottle caps, pieces of rebar, etc. This facilitates the search and saves the user from the extra work of extracting uninteresting objects from the ground.
