1. Different hardnesses: Compared with MH-adjusted carbon and M-adjusted carbon, the hardness of MH-adjusted carbon is higher than that of M-adjusted carbon. MH is medium hard, while M is medium between medium soft and medium hard.

2. Different usage sites: M is generally used in freshwater areas because it is between medium hard and medium soft, while MH is medium hard and has higher hardness, so it is generally used in deep sea.

3. Different types of fishing: M is mostly used to catch fish in rivers or lakes, while MH is mostly used to catch sea fish.

Extended information

Lure rods are generally relatively long, with some single sections reaching 2.4 meters in length, which makes material production extremely difficult! Because making materials is a physical/chemical reaction process, it is also accompanied by changes in temperature and internal stress.

So it is almost impossible to keep the material straight. When selecting a lure rod, insert the rod, align the guide ring, hold the rod with both hands, place it on your chest, raise the tip of the rod slightly, look for a white or gray background to avoid interference, concentrate, and stare at the tip of the rod ( Generally, the tip is easier to bend) and you can see the bend.

In the earliest fiberglass rods, after the wires were tied, the guide ring was first used, and then the burrs were burned with an alcohol lamp, primer, and UV paint. The so-called UV paint is a photosensitive paint that solidifies quickly under ultraviolet irradiation. The advantages of UV paint are fast working efficiency and high brightness. But it has the biggest disadvantages: poor toughness, low strength, and poor adhesion. When subjected to strong force, it will burst.
