What does fishing rod 28 mean?

The tonality of the fishing rod indicates the hardness of the fishing rod. The key of 19 indicates that the fishing rod is super hard, and the key of 28 is slightly softer than the key of 19, which is also a hard key.

The division method of tonality is to divide the fishing rod into 10 equal parts, hold the rod horizontally, and the intersection position between the radian formed by natural bending of the rod body and the straight part of the rod body is the basis for judging tonality.

For example, the tangent point of the last arc is a superhard tuning bar, also called 19 tonality; The first two paragraphs are hard tuning, also called 28 tonality, and the first three paragraphs are middle tuning, also called 37 tonality; The first four segments are soft poles, also called 46 tones, and the first five segments are super soft poles, also called 55 tones.

Extended data

Generally speaking, there are two ways to mark the tonality of fishing rod, one is to directly mark the hardness, such as soft tone, hard tone and ultra-hard tone, and the other is to mark the digital proportional tonality, such as 28 tone, 19 tone and 37 tone.

Stretch the whole fishing rod horizontally and give it a vertical downward force at the tip of the rod. At this time, the front part of the fishing rod will bend and sag, while the back part is still straight. The less curved parts there are, the harder the tonality of the fishing rod will be.

If the curved part accounts for 1 of the whole fishing rod and the straight part accounts for 9 of 10, it is called 19 key, while the 28 key is 2 of 10 for the curved part and 8 of 10 for the straight part, and so on.

Fishing rod is one of the most basic fishing equipment for fishermen, and it is also an easily damaged product. After all, the price of an ordinary fishing rod is around 100 yuan, and the frequency of ordinary fishermen upgrading their fishing rods is not very fast.
