The flat-bottomed cup-type hole breaker is shaped like a stainless steel flat-bottomed cup, and the cup body is covered with small holes. After the nest material is put in, the hole breaker has a quick link, which can be directly hung on the eight-character ring and then swung to the fishing point. When the hole breaker and the nest material sink to the bottom, the fishing rod is lifted gently, and the nest material is dumped at the bottom of the water, so that the nest material is very concentrated.
As the name implies, the hole breaker is an auxiliary tool for making holes. There are five kinds of common hole-breakers, namely, hole-breaker, hole-breaker bag, ball hole-breaker, hole-breaker throwing and hole-breaker boat.
