Don't throw away your empty plastic spools after you have used the lines.
Get the portable despoiler to despool lines from your reels so you can clean and maintain your reel spools in tip top condition and prevent spool corrosion!.
The despooler has a revolution counter. Measure your plastic spool circumference and multiply but the revolutions and you have a good idea how much you have in that plastic spool. I mark what reels I offload the lines from so I know which reel to use them on when the need arises.
Please note this is a DESPOOLER. the motor is too small and not powerful enough to apply tension to spool and packing lines back into reels properly.
I have 12 sets going at 45$ each self collection.
Please whats app me if you need. 90042286.
I have designed the plastic spool holder such that most plastic spools that you buy your lines in can be recycled.
