SONAR Leader

So you're out on the river with only a floating line at your disposal, and all the fish are feeding below the surface. Not to worry, the Scientific Anglers SONAR Leader has your back. With four different densities that sink to different depths, you can fish anywhere in the water column without breaking out an entirely different fly line.


  • Put your fly anywhere in the water column with these leaders
  • Different densities sink to different depths
  • Works with single- or double-handed lines
  • Item #SAS003I
