Throw the fishing group to the center of the water. When the plumb is falling, the roller will pull back 2 to 3 meters, and the direction of the valve stem will be 60-90 degrees from the fishing line. The angle is larger. The chances of running a fish are smaller. If the water is shallow, the angle between the tip and the water surface will be larger. If the water depth is close to the surface of the valve stem, it is convenient to reduce the angle between the fish line and the bottom of the water, which is more conducive to bottom fishing.
The important point here is the degree of tight line. Due to the softness of the valve stem, a small external force can bend the tip. The degree of the tight line is that the tip of the shank is slightly bent. Even the fishing line has a large arc, but this is fine. This effect is best. When the squid is gently pulled, the squid will suddenly bend and tremble. Never bend the tip as a bow, if you lose the meaning of the stem.
