Mastery Uniform Sink Plus Fly Lines

Just as Scientific Anglers™ invented modern floating fly lines more than fifty years ago, it wasn't long after that they also introduced the first generation of Wet Cel™ full sinking lines. Today, they continue to lead the industry in quality and reliability - and in providing the ideal sinking fly line for every situation.

Fish feed below the surface 90 percent of the time - but at a variety of depths. Every sinking line in this comprehensive selection has been designed to keep you in a specific zone thanks to precise formulations that produce precise sink rates.

Each of the Mastery full sinking lines is designed with an effective range of performance. When you reach the limits of a line's effectiveness, you should switch to a different line density. You should also increase sinking-line density when there is an increase in current speed, rate of retrieve, or depth.
