Sonar Sinking Leaders


Imagine a world where you need to get a fly down to the fish, but all you have is a floating fly line. In that world, the perfect solution would be our SONAR Sinking Leaders. Luckily for you, we live in such a world. These leaders attach to the end of a fly line and can put your fly anywhere in the water column. Sonar leaders feature welded loops on the rear end and a micro-swivel on the front end to reduce line twist. With five different densities you’ll be able to cover the surface to the depths. Ideal for single-handed lines as well as light double-handed lines, no matter the scenario, you can Get Down with SONAR.

  • Floating and sinking leaders for use with double and single-handed lines
  • Welded loop on butt end with micro swivel on front end (No swivel on floating)
  • Built on 25-lb. monofilament
  • Features printed Line ID to easily identify density and length of the tip
