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 the 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.
