How to choose fishing gear?

When you walk into a fishing tackle shop and face a dazzling array of fishing tackles, how would you choose a fishing rod that you want? Below, we briefly introduce the basic method of selecting fishing rods:
First of all, we must recognize and understand the meaning of various labels on fishing rod packaging. Because this is the main technical indicator of the fishing rod, and also the main basis for our quantitative analysis of a fishing rod.
These indicators include: total length, number of knots, contraction length, first diameter, element diameter, dead weight, materials used, carbon content, net fishing weight, and fishing performance. Understanding the meaning of these indicators, we can find out the connection and logical relationship between them.

Secondly, we can measure the inner quality of fishing rods based on these connections and logical relationships. For example, the self-weight is determined by the total length, the number of nodes, the shrinkage length, the diameter, the diameter of the element, the materials used, and the carbon content. Assuming: the total length, number of knots, contraction length, initial diameter, and element diameter remain unchanged, then the material used and the carbon content are a function of the weight of the pole. Under the premise of ensuring net fishing weight, the lighter the weight, the higher the quality! Conversely, only by using high-tonnage carbon fiber cloth to increase the carbon content of the pole can the weight be reduced. If two fishing rods have basically the same indicators, the one with lighter weight is better than the one with higher quality. Of course, we must also consider whether the workmanship is exquisite, whether the painting is exquisite, and whether the price is appropriate, but these are not within the scope of quantitative analysis.
And so on: If the indicators of the two fishing rods are basically the same, then:
The quality of light weight is better than weight of weight;
High net fishing weight is better than low net fishing weight;
The quality of the thinner diameter is better than the thicker diameter;
High carbon content is better than low carbon content.

This is a simple quantitative analysis method that can help us rationally recognize fishing rods. It is also a reference for fishing rod design, manufacturing and pricing. After understanding the meaning of various indicators of fishing rods and the logical relationships between them, we can first determine the main performance indicators of fishing rods according to the purpose of purchase, and then choose fishing rods based on this indicator. For example, if we want to fish for large fish such as carp, grass, green, silver carp, and bighead carp, the first indicators we must refer to should be net weight, tonality and full length. These three indicators are determined, and other indicators can be combined according to the cost performance. Fishing rods with high prices are not necessarily the most suitable for us. Only by achieving rational cognition can we achieve rational consumption.
