The Varivas Casting Shock Leader MAGURO is specially designed to make ultra-resistant leaders for tuna fishing. This leader is able to withstand lightning fast starts thanks to its carefully measured elasticity and to resist rubbing by other tuna thanks to its super-resistant coating. Available in lengths of 30m, with diameters ranging from 0.91 mm to 1.47 mm and strengths from 105 lb to 220 lb, its transparent pink color ensures optimum discretion.
