Two versions of the equipment are available, having their own design features. The first versions is designed for work at sea depths of 20–200 m, and the second is specially designed for the study of transition zones 0–50 m, where the undercurrent and sea disturbances have a serious impact on the operation of the equipment. Both types of equipment are produced in five (Ex,Ey,Hx,Hy,Hz) and two channel (Ex, Ey) versions. The equipment is equipped with radio and acoustic communication modules. Synchronization is performed on the deck of the vessel, then the system is sealed and immersed. The system is surfaced by an acoustic signal from the surface of the water. The light radio beacon makes it easy to localize the system on the surface of the water even when the sea is rough.
