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 leader to get buried, so bites might be easier to detect? Dobon Rig, Lead Weight 0.5g x 4 The line is 5-gauge nylon. Please be careful as the main line will break if the weight gets snagged. How to use: Remove the leader from your bottom fishing rig and attach the snap of the "dobon" rig there. Set the leader on the swivel. A shorter leader (top 10cm, bottom 15cm) seems to provide better sensitivity, but Marukyu's Hera Bait Power Book recommends top 20-30cm, bottom 35-50cm. If you prepare a separate weight, you can change the weight. For light "dobon" use up to 0.8g, and for normal "dobon" use 1g to 2g. Also, when returning to balanced bottom fishing from "dobon," before changing to "dobon," attach a "tombo" (a type of line stopper) to the lower float stop as well. This position will become the balanced level, and you won't need to take the depth measurement if you return the float to this position. Also, when changing to "dobon," you can leave the balanced weight and float as they are, but you can slowly settle the bait by increasing the float size without cutting the weight. 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.
