    Due to the particular interaction between the search coil and these types of targets certain difficulties arise. This is due to the very narrow difference between the vector angle of these targets and those of the ground signal. Fig. 26 ООО «фирма «АКА», +7(495)621-0481, http://aka.2000.ru aka_md@mail.ru...
