How do you know if your baitcaster is bad?

You can tell if your baitcaster is bad by checking for excessive backlash, which indicates issues with the braking system or spool tension. If the reel makes unusual noises while retrieving or has a rough feel when cranking, it may have internal damage. Additionally, any visible signs of wear, such as frayed line or damaged components, can signal that the reel needs repair or replacement. Lastly, if the drag system fails to hold or slip under tension, it's a clear sign of malfunction.
