This German made serving tool is the ultimate tool for the serious angler. The Beiter Winder Profi has stainless steel rollers and end lugs, designed to give the tool maximum weight and inertia for serving leaders 50lb and above. The stainless parts interchange with high-impact plastic, making the tool ideal for serving leaders 20-40lb. The Beiter Winder Profi has an easy clip-in system for the thread, fine adjustable drag, and quick-change serving spools. We include one aluminium spool for free, which is CNC machined by Busted Fishing. The spool holds 70 meters of 20lb spectra (line not included).
