This is a "Dobon" rig that can be connected to a balanced bottom fishing rig with a single touch. ＜The replacement weight shafts, snap swivels, tube colors, and types of transparent bags may differ from the photos＞ ★Why not switch from balanced bottom fishing to Dobon fishing during the cold season, when the fish are not biting, or when the float is drifting in the current? When fishing is difficult due to wind, Dobon fishing makes it easier to cast and retrieve because the weight is heavy. It's a waste to give up and go home, isn't it?

Photo 6: Replace the weight. Photo 5: Grasp the tube and push up the lower end of the hardware with your finger. To use, remove the hook length from the bottom fishing rig and attach the snap of the Dobon rig there. Set the hook length on the swivel. It seems that shorter hook lengths (top 10cm, bottom 15cm) provide better sensitivity, but Marukyu's Hera Bait Power Book recommends top 20-30cm and bottom 35-50cm. For light Dobon, the weight is up to 0.8g, and for normal Dobon, it seems to be around 1g to 2g. For bottoms where sludge has accumulated, it is recommended to use the medium balance hardware (3cm). If you want to return to balanced bottom fishing from Dobon, attach a "tonbo" (a type of float stopper) to the lower float stopper before switching to Dobon. This position will become the balance level, and you won't need to measure the depth if you return the float to this position. Also, when switching to Dobon, you can leave the balance weight and float as they are, but if you increase the float size without cutting the weight, you can let it settle slowly. Since you haven't cut the weight, you can easily return to balanced bottom fishing by returning the float size. ★Use 5-go line. Be careful as the main line may break if the weight gets snagged. In areas with many snags, when using 1-go main line, I disassemble the rig and reassemble it with 5-go to 0.8-go line. Please note that returns and claims are not accepted.
