Carp is a kind of fish that can be easily seen in fresh water, and fishing for them is also an activity that anglers often carry out. Sub-line is one of the necessary tools for fishing carp, which belongs to a kind of fishing line and has a great influence on the fishing effect like the main line. When selecting sub-wires, the degree of thickness is an important issue, and one aspect related to thickness is the size of the model. Generally speaking, it is more appropriate to choose between 0.8 and 1.5 sub-lines.

However, when choosing, the specific models of sub-lines are different because of the different body shapes of carp. For example, when fishing for large carp, it is also necessary to use large and thick sub-wires, so as to prevent carp from breaking the sub-wires when taking the bait. On the contrary, use a smaller sub-wire of the model. In addition, it should be noted that the model of the main line needs to be larger than the model of the sub-line.

As mentioned above, the sub-line is an important tool for fishing carp, not only the model is an important aspect, but also the length is an important aspect. Generally speaking, when fishing carp, the length range of sub-lines used is basically between 20 and 30 cm, and the sub-lines in this range can basically meet the specific conditions of all fishing carp.

However, in different fishing situations, the specific sub-line length to be used is not exactly the same, and sometimes it will change greatly due to the change of some factors. The size of carp is an important aspect. When fishing carp of different sizes, the length of sub-line is also different. When fishing carp is small in size, shorter sub-lines are generally used. The larger carp are distributed in a relatively deeper position, so the sub-line needs to be longer at this time.
