TheScientific Anglers SONAR Saltwater Intermediate fly line features a slow-sinking clear head that cuts through the surface and provides an amazing amount of stealth for those wary fish cruising the flats. From redfish and bonefish to permit and tarpon, give yourself an edge that fish won’t be able to see.
