Portable magnetometer for vector magnetic survey LEMI-013 is intended for 3-components vector magnetic survey at regions with complicate geological configuration of subsurface objects. Portable magnetometer is designed on the base of small-sized high stable 3-components fluxgate sensor that fixed tightly on the optical tube of non-magnetic theodolite and data acquisition unit with built-in GPS receiver. The magnetometer contains inner non-volatile memory for field data storage and built-in battery. Special software gives possibility to correct vector magnetometer readings accordingly to the synchronous data of reference magnetic variations station placed nearby investigated site.
