You won’t find any magnets in the new Quantum reels. What you will find, besides standard spool tensioning, is a new concept in centrifugal braking called ACS (for Adjustable Centrifugal Braking). Instead of having to remove the side plate and spool to fuss with the shoe settings-the normal procedure-there’s an external control that does the job, set flush with the frame so that you can’t accidentally knock it out of tune. In fact, it’s the first external design for centrifugals. You can adjust the reel to engage the eequivalent of two, four or six brake shoes..or none at all.
