SJ is right. Some guys dont realize that the Idurons have brakes.
Unscrew the 2 small skrew knobs on the handle side of the reel. Now pull that half of the reel off of the frame. Remove the spool and the brakes are on the side of the spool. I would start by moving 3 of the brakes to the on position. Thats moving them outwards. Put the reel back togethr and fish it. Use the cast controll knob to fine tune it. If its not casting far enough take a brake off. If its still too "free" put another brake on. The Indurons are great casting reels. Once you get your brakes dialed in you will love them again.
