It seems there's an outside-line Tone-style "dobon" rig that uses a Swing Pet guide float, but this is a "dobon" rig with an outside line using a "shimori pet," so perhaps it can't be called Tone-style? ★Even on bottoms where sludge has accumulated, the "shimori pet" makes it less likely for the hook length to be buried, so bites may be easier to detect? Dobon Rig: Lead weight 0.5 go x 4 pieces Line: Nylon size 5. Please be careful as the main line will break if the weight gets snagged. How to use: Remove the hook length from your bottom fishing rig and attach the snap of the "dobon" rig there. Attach the hook length to the swivel. Shorter hook lengths (top 10cm, bottom 15cm) seem to provide better sensitivity, but Marukyu's Hera Bait Power Book recommends top 20-30cm, bottom 35-50cm. If you prepare additional weights, you can change the weights. For light "dobon," up to 0.8 go, and for normal "dobon," it seems to be around 1 go to 2 go. Also, when returning to balanced bottom fishing from "dobon," before switching to "dobon," attaching a "tonbo" (a type of line stopper) to the lower float stopper will make this position the balance level, and returning the float to this position eliminates the need for depth measurement. 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 get a slow sinking action. Since you haven't cut the weight, you can easily return to balanced bottom fishing by returning the float size. Please note that returns and claims are not accepted.
