Sinking Fly Lines

Soon after Scientific Anglers™ invented modern floating fly lines, we also introduced fly fishing's first modern full-sinking lines. Today, we continue to lead the industry in quality, reliability, and selection. Fish feed below the surface 90 percent of the time at a variety of depths. To reach them, you need two things: A line designed for the specific application and a line that keeps your fly in a specific strike zone. Scientific Anglers™ sinking lines excel in both areas. Our advanced tapers, cores, and coatings produce the most trusted performance in fly fishing, and our precise formulations produce consistently accurate sink rates that help keep your fly in front of feeding fish.
