This is a set of 4 twin assist hooks. These assist hooks were designed and created to improve my own fishing results, and I use them for targeting Spanish mackerel and yellowtail. The hooks use modified Soi (Nano Smooth Coat). The assist line is made of Zylon Knot #40 in a loop (double), so it has excellent strength. Please try these before you have to experience the frustration of a broken assist line. The assist line is a short 15mm specification. How about using them as a countermeasure against Spanish mackerel cutters? You can use the hooks facing outwards or inwards as you prefer. They are made to fit short jigs like the popular Quick Zero One 200g and Jack Eye Slow 200g in Ise Bay jigging. Please understand that there may be some variations due to being handmade. If you would like to purchase multiple sets, please comment and I will discount the price according to the number of sets. #Jigging #SlowJigging #IseBay #IseBayJigging #JiggingBattle #Bluefish #Yellowtail #JapaneseAmberjack #GreaterAmberjack #SpanishMackerel #Gamakatsu #BOZLES #cbone #QuickZeroOne #z4 #KosoJig #JackEye #Boccone #Golaso Fishing type/Fish type: Jigging Lure/Fly type: Metal jig Fishing type: Jigging
