Weighing in at only 6.5oz, the Shimano Chronarch 150 CI4 Casting Reel takes reel performance to a whole new level. Lighter and more advanced than ever before, its CI4+ construction allowed Shimano to greatly reduce its overall weight, while still maintaining incredible rigidity and strength. Actually 250% stronger than the original CI4 material, CI4+ is also over one-and-a-half times stronger than Shimano’s normal XT-7 graphite and is over 20% lighter as well. Since CI4+ does not contain any metal, it is impervious to rust, making the Chronorch CI4+ a great choice for fishing saltwater or brackish water.
