1. Fishing when the hook falls to the bottom. Underwater hook fishing is a double-edged sword. Fishing with the hook at the bottom of the water has absolute advantages, and it is also a kind of "dull fishing". When fishing big fish, false signals can be avoided and the phenomenon of anchoring fish can be avoided.
2. The hook slightly touches the bottom of the water, which is convenient for fishing. The hook touches the bottom usually when the fish mouth is not good, and sometimes the fish will leave the bottom because of the water temperature difference caused by lack of oxygen or weather factors. At this time, reducing the proportion of float and hook lead can make one hook off the bottom and the other hook touch the bottom slightly, which is suitable for slow fishing when the fishing mouth is not good, and sometimes it is also used to find fish layers. This species is not suitable for catching benthic fish, such as silver carp, bighead carp, grass carp, carp and crucian carp.
3. The hook is completely separated from the bottom. With the popularity of platform fishing, the phenomenon of fishing with hooks off the bottom is very common, especially in areas with complex underwater terrain and many obstacles. These places are easy to get hooked, and catching fish under the pole is small, so you need a pair of hooks. And when fishing grass carp in summer, the effect of fishing with the hook completely off the bottom is much better than that of bottom fishing.
