You don’t build a product this exceptional by going with the flow. So while most of the fishing industry focuses on smaller reels with tiny spools, Quantum engineered a larger 35.5 mm spool into a very compact frame to provide anglers plenty of line capacity, longer casts, and more inches of line pick-up with every turn of the handle, compared to smaller spooled reels currently littering the fishing industry. However spool size becomes somewhat irrelevant without a top-notch braking system, so Quantum performed a tremendous amount of engineering research to develop a ACS 4.0™ cast control that is lighter in weight which minimizes the amount of energy it takes to get the spool spinning on a cast, along with additional brakes that disengage around 5,000 RPMs to maximize distance.
