The numbers on the reel listen for a minute spool measurement you can utilize, either 4000, 3000, 2500, or 1000. Recollect that the bigger the distance across, the more line your spool can hold. A 2000 spool is equipped for holding 150 meters of size 2 nylon lines while a 1000 spool can hold 150 meters of size 1 nylon line.
