Is there a difference between fishing with four eyes, fishing with two eyes and fishing with three eyes? A hook (double hook or single hook)

To be exact, there is a difference. Of course, under the same conditions (but only in theory, it is good to understand), the actual fishing is of little significance. Both of them have two purposes: the bait carries buoyancy, but the four-fishing has two purposes of residual buoyancy, while the three-fishing has only one purpose of residual buoyancy, expressing different fish information. For example, a small fish eats the bait in two floats, which is the next one, and a big fish eats the bait, which is the next two. However, it is the same with one eye (black drift) and two eyes (big fish) (except that the hook is small and the drift tail is thick, which is only a more realistic theory. The adjustment you asked is on the low side. The actual situation of adjusting the fourth gear and the second gear is the same as that of adjusting the third gear. If it's shifting the sixth gear, the fourth gear and the third gear are completely different). Of course, it is two hooks, and one hook is another matter. It is not recommended to use a hook (except for traditional fishing, which is suspected of escaping from reality).
