Description The PR Bobbin from Shimano is strong, lightweight and simple device that can achieve stunning PR knots and binds with ease. It comes with a built-in line tensioner as well as double O-rings to lock in your braid, preventing slippage during your winding. It also features a hard zirconium ring at the tip that reduces heat and friction by allowing the braid to run smoother under tension. Available in both a small (PE 0.3 to 3.0) and large size (PE 1.5 to 8).
