Adjust a few times, fish a few times, and find out.
The first three steps are the same as yours. For example, if the hook is adjusted to six eyes without hook and the hook becomes three eyes, then the hook weighs one and a half eyes. Pull up and float from three eyes to four and a half eyes, that is, from one hook to the end, from four and a half eyes to six eyes should be from one hook to the end, and from six eyes to the end. This is the most comfortable way to find out the bottom.
It should be noted that when looking for the bottom, it is best to hang two plasticine the size of a bait ball on the hook, so that the bottom found is the most accurate. Also, the auxiliary line must be soft. Sub-wires cannot provide an upward supporting force for the whole wire group because they are too hard. This method of drift adjustment is very important, otherwise it is not allowed.
