It means that the fake bait vibrates to attack the fish under water. VIB can search the bottom of the water, jump on the bottom of the water, or jump off the water at various depths to use the vibrations generated by swimming strokes to lure fish. In order to reduce the occurrence of bottom hanging, the three hooks on the bait can be replaced with chicken hooks (also called two hooks) or even single hooks.
Sequins are also divided into different types, common spoon-shaped sequins, beveled sequins, rotating sequins, etc., mainly rely on the sequins to flip the reflected light underwater to simulate the effect of bait fish escaping and reflecting under the water. The vibration function makes the sequin fishing function more abundant. It is very useful for fast-moving and aggressive fishes, such as billfish in fresh water, perch in bay water, mackerel and so on.
Iron plate is also called jigging, and now there are not only shovel fishing in sea fishing, but also freshwater iron fishing in freshwater. The technique of iron fishing is slightly different from ordinary lure fishing techniques.
