It is a simple fact that today’s super fast multiplier spools need to be balanced to run smoothly. Very much like a car wheel, components that rotate need to be balanced to avoid vibration and run true. Assuming the reel spool itself is in thoroughly good order, and not distorted or bent in any way, balancing is a straightforward process that anyone can do. So, how do you balance the line on your spool? I have found over 20 years plus of spool balancing that the first 20 to 30 metres of line on the spool determine the balance.
Follow the picture sequence below…
After completing these five stages, wind off any magnets, remove brake blocks and give the spool a good hard flick to get the spool running as fast as possible, and feel/listen for any vibration. If vibration is apparent, remove the line and change the height and position of the line humps until it comes right. Some spools balance up with little effort while others will take any number of attempts to get right.
