The Stillwater Fishing Line Spooler is a great little tool for quickly spooling up line onto your Reel. Slide the tension knob off and insert a spool of line, re-apply the tension knob and fix it against the spool until you have good resistance. Secure the spooler easily, using the suction cup base. This spooling station can hold small (125yd) or bulk-sized(1000yd+) spools of line. A fast, easy and reliable spooling solution.
