This application describes a braided cord containing a braided sheath and optionally a core surrounded by the braided sheath. The braided cord has changing cross-sectional area ranging from 0.0004 mm.sup.2 to 30 mm.sup.2 and contains one or more sections having a tapering angle ranging from 1° to 60° when observed in one direction along the cord axis. The change in the cross-sectional area of the cord can be achieved by changing the thickness of the braided sheath and/or changing the cross-sectional area of the core when the core is present. The thickness of the braided sheath can be adjusted by changing the size and/or twist level of one or more sheath strands, changing the pick count of the braided sheath, and/or using one or more shaped sheath strands. This application also describes a process of producing the braided cord with changing cross-sectional area.

Proposed is a fishing line preparation instrument for a fishing rod guide ring, the instrument being capable of allowing a user to accurately rig a fishing line to a plurality of guide rings and shortening a rigging time. The fishing line preparation instrument is used for a blank type fishing rod in which a plurality of guide rings are disposed at fixed intervals, and includes a guide ring insertion member configured to be inserted into the plurality of guide rings, and a fishing line fixing part provided at least one of a first end and a second end of the guide ring insertion member and configured to removably fix a fishing line to the guide ring insertion member.

An electrical transmission line cable suited for a variety of applications, including as a fishing line in a video fishing system. The electrical transmission line cable has a first conductor and a second conductor forming an electrical transmission line; a jacket containing the first conductor and the second conductor; and a transmission line primary dielectric element separating the first conductor and the second conductor, wherein the primary dielectric element is at least one of textile yarns, fiber yarns, or monofilaments. The electrical transmission line may be in a balanced configuration or an unbalanced configuration.
