With the Scientific Anglers® Wavelenght Grand Slam you can get a Tarpon, Bonefish and Permit. All in one day. All on one line. That’s the idea behind this line, a fly line designed specifically to help you achieve one of angling’s most elusive accomplishments. With a short, powerful head the Grand Slam cuts through wind and turns over crabs, shrimp, and tarpon toads with ease. We’ve got the line. You just need the fish.
