How to adjust the standard of traditional fishing seven-star drift line (line length 15CM) double hook? How to add or subtract the weight of lead skin?

There are actually only six seven-star drifters in the fishing gear shop. Adjust the lead skin first, so that the five stars can surface on the premise that the double hooks are off the bottom. Then, on the premise that the bait is hooked and separated from the bottom, the distance between the stars is adjusted so that just four stars emerge from the water. At this time, it can be concluded that the weight of a bait is equal to the buoyancy of a star drift. Hang lead skin on the hook to find the bottom, and adjust the other stars to float according to the same distance between the fourth and fifth stars, so that one star floats out of the water and the second star floats half in the water; ? At this time, the drifting is over, and the hanging double bait stars emerge from the water, that is, they are undercover in the ditch and touch the bottom with hooks.

Seven-star drift is most suitable for fishing in still water or waters with little influence from wind and waves. Its advantages: it is light to enter the water, it is not easy to disturb the fish at the fishing point when lifting the pole, and it will not produce too much resistance when leaving the water. It's very simple to use. Usually, when you match the fishing group, you only need to adjust the float once, and then you don't need to adjust it again. Even if you fish from shallow to deep, you just need to clean the float. When you need to float, you can erase all the floats. When you need to fish for the bottom, you can wipe a few floats up to reduce some buoyancy.
