This underwater towed search engine as follows:

Before descending from the vessel 1 light carrier 4 is (pre-placed) within a niche 7, lightweight cable 5 is wound on the winch drum 6. The cable 14 is pulled by the spring 13, the carriage 9 is in its extreme rear position. In this configuration, the system displays the vessel 1 and is omitted due to grazing cable 2 to a predetermined depth. The descent is made mainly in the mode of drift or go to very small vessel. Upon reaching the desired depth light carrier 4 out niches 7. This ship is given a move - winch 6 is enabled to issue a lightweight cable 5 and the carriage 9 due to the force of the spring 13, acting through the variable geometry mechanism 15 and the cable 14 is moved in the direction of the stern of zaglubitelja 3 and resting on the nose of a light carrier 4, pushes it out of the niche 7. Conclusion easy media niche and contributes hydrodynamic force to fight the Oia light media. When he reached the rear stop, the carriage 9 is stopped, lightweight cable 5 is issued by the winch 6 to a predetermined length.
