An Intermediate Sinking Line With A Completley Clear Head - Essential For All Lake Anglers

RIO’s Aqualux II line has a 30ft, clear intermediate head that sinks about 1.5 to 2 ips, and is deadly efficient for fishing between 2ft and 6ft in depth in stillwaters. The short head makes it very easy to cast, and reduces the number of false casts required to get the line out - resulting in more fishing time. The head integrates seamlessly in to a translucent green, intermediate sinking running line that is super slick, and shoots with the utmost ease. Each line features a welded loop in the front end for fast rigging.

For fishing flies just below the surface

One day, long ago, in a kingdom far, far away, we dreamed up a line that would sink, but not sink too much, one that would simply hover beneath the surface. Fast forward thousands of years and the SONAR Stillwater Hover sinking fly line was born. Built with an extra-slow sink rate, the Hover is downright nasty when it comes to fishing streamers with a slow retrieve. It’s a legend, at least in our own minds.

Double-density sinking lines

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.
