How to use float 1, 2, 3? Which drift is the best?

The floating semicolon is designed to adapt to different fish conditions, different rod lengths, different line groups and so on. Most floating points of the same type are divided into 1, 2, 3, some are divided into 6 to 8, and 1 is the minimum. Small drift is suitable for catching smaller fish with short rods and thin lines. Sometimes when fish are small, they use small floats, while big floats are the opposite. But these are not generalizations. Generally speaking, the smaller the drift, the smaller the buoyancy, the smaller the matching line group, the more sensitive the drift signal and the greater the drift. There is no best float, and there is no best number. For the same kind of fish, you can use 1 to catch fish, or you can use No.2 or No.3 to catch fish, but their signals are different. Only anglers can choose floats suitable for fish mouths according to their own experience. Deep-water fish drift slowly with small ones, while shallow-water fish drift fast with large ones. Use a large float for the coarse hook and a small float for the fine hook.
