Scientific Anglers Sonar Seamless Density Sinking Fly Line

Product Code
18A0061
£109.99
Specification

Seamless Density technology provides a smooth transition between densities, eliminates hinging and provides a straight line connection to the fly.
Available in three models

The Sonar Stillwater Seamless Density lines are a unique departure from the traditional graduated density lines of years past. With a variety of double-density sinking rates and a smooth, seamless transition between each, the Sonar Stillwater Seamless Density lines provide straightline connections to subsurface flies, meaning you’re in control of the fly every second it’s in the water.
