Step 1: Weigh the lead skin so that the weight of the lead pendant is greater than the buoyancy of the float. Quickly find the bottom and let the float sink into the water.

Step 2: Lift the pole to trim the lead skin, then throw the pole to make the float out of the water, trim it bit by bit with scissors, never cut it, and try it several times.

Step 3: Hang bait (earthworm, red worm, bait can be used), throw the rod and see how many eyes the float is above the water. If it is an eye, move the float upward by the target distance to make the float out of the water for two eyes, that is, adjust four and catch two.

Note: floating is very sensitive, and the requirements for the bottom of the water must be gentle in order to give full play to its skills.
