To adjust four and two, we must first find the bottom of the lead. Heavy lead is that the lead skin rolled up by the lead pendant exceeds buoyancy. When the wire group is put into the water, the lead pendant will fall to the bottom of the water. At this time, the float is also submerged. Move the float upward repeatedly to make the float out of the water 1 mesh. The distance from the top of the lead float to the water surface is the distance from the water surface to the bottom. )
Adjust the purpose. The float moves downward (the distance is about 5- 10 cm longer than the length of the sub-line), at this time, the float sinks into the water again, and the lead pendant still falls to the bottom of the water.
Cut the lead skin slowly and put it into the water several times to observe the float. When the float is exposed to 4 eyes, the adjustment of purpose is completed. At this time, the lead pendant is suspended and the double ditch is off the bottom.
Adjust the fishing purpose. Hang the bait on the bottom hook (or a rubber). At this time, the gravity of the bait is greater than the buoyancy of the float, and the float sinks into the water again. The bottom hook just touched the bottom and the hook hung in the air.
Move the float up slowly. When the float leaks out of 2-3 meshes, the bottom hook still touches the bottom and the hook is suspended.
