System for suspending a longline at the desired depth and for marking a sea zone

摘要

A system is described which achieves the suspension of a longline at the desired depth from the sea bottom or sea surface which can be also used for marking a sea zone. It consists of a base (6), a head (11) and a fishing line (10) which connects the two parts. It is applied very fast by pressing the button (7) onto the central fishing line of the longline and simultaneously develops so that during its immersion it has the correct form, without any time delay. It improves the efficiency of the longline and protects it from getting messed. When the case (5) of the head (11) is a buoy and the base is a ballast, then the system is immersed and is applied to sea bottom longlines. In the opposite case it floats and is used in surface longlines. Being applied 50 to 100 meters along the central fishing line of the longline it can be suspended at a pre-selected distance from the sea bottom or the surface but also to mark a sea region very fast when applied to a rope which does not need any pre-treatment which suspends it to the desired depth. It is stored in a compact form and locks its fishing line (10) from unwinding inside its storage space.
