The most popular drift adjustment method in Taiwan fishing is to adjust four catches and two catches. Among them, "tune" refers to the number of squares exposed by floating without bait; "Fishing" refers to the number of squares exposed by floats after baiting. Adjust the weight of the lead skin and the position of the float before feeding, so that the float reveals four eyes, and after feeding, adjust the position of the float to reveal two eyes.

The specific methods of "adjusting four" are as follows: a. weighting the lead skin to make it slightly larger than the buoyancy of the float, and adjusting the position of the float to make the distance between the float and the lead seat smaller than the water depth. So after entering the water, the float is pulled into the water by the weight of the lead skin and submerged by the water. B carefully cut off the lead skin a little at a time, and adjust the weight of the lead skin on the lead base, so that the float slowly emerges from the water. At this point, the "four adjustments" are completed! (Note: At this time, the buoyancy of the four eyes exposed by the float is equal to the weight of the lead skin and the hook, and the hook is suspended in the water.)

The specific methods of "fishing for the second time" are as follows: a. After the "four adjustments" are completed, the bait is put into the water, and the number of floating eyes is reduced (personally, if the float sinks into the water, or the number of floating eyes is greater than two eyes, the bait is heavy, light or inappropriate). B. Move the float seat upwards, and increase the distance between the bait and the float (the mesh number should remain the same until the bait touches the ground), until the mesh number rises to two meshes (because Taiwan fishing uses a double hook with one long thread and one short thread, the other hook does not touch the ground after it touches the ground, and after this hook touches the ground, the weight will be reduced and the float will float a little).
