What's the use of fishing buoys

The language of the buoy is hard to say clearly. Can only be simply said. The function of the float is to transmit the information of the fish biting the hook to the angler through action. According to the action of biting the hook, the fisherman can judge the type and size of the fish ... It can also detect the depth of the fishing waters and display the position of the bait hook. Floating can also change the fishing method. The buoyancy of the float can be used to adjust the fishing group in the water. ........
