"To summarize the relationship between fishing target and buoyancy adjustment in one sentence, it's the interplay between the remaining buoyancy and the weight of the bait that affects the different states of the double-hooked line underwater!"
If the remaining buoyancy is greater than the weight of the bait, and it's not bottom fishing, then the float can lift the double hooks off the bottom, and the entire main line is stretched tight! At this time, the whole line setup is in its most sensitive state!"
If the remaining buoyancy is less than the weight of the bait, but greater than the weight of the bait on a single hook, then in bottom fishing condition, the top hook might be lifted by the float, presenting a state of one bait suspended and one bait on the bottom underwater!"
"This is a simple problem of force analysis and state judgment. With just a slight concept in mind, one can figure it out clearly!"
