Placement and fastening of throughput rings.




Rings throughout the rod are placed on the same line. In the event that the rings are not placed on the same line, when casting, the friction of the fishing line on them increases. This affects the casting distance. When playing a fish, the discrepancy between the circumferences of the rings disrupts the distribution of forces along the rod, threatening to break it.


Rings are attached in certain places of the rod from the handle to the tip inclusive. The ring attached to the tip of the rod differs from the others not only in size. It has a device different from other rings and is located at a certain angle to the axis of the rod, which is especially important when building tackle for angling large fish.


Since the main load falls on this ring when playing the prey, it is attached in such a way that the plane of the ring is shifted relative to the axis of the rod by an angle of 50-70 °. Because of its shape, the end ring is called a "tulip".
