Designed with a short, fast-sinking head, the Scientific Anglers Sonar Sink 25 Fly Line gets deep extremely fast and is paired with a large handling section for excellent line control.

When it comes to fishing streamers in cold water, its difficult to beat the Sonar Sink 25. This line is an excellent streamer line and has a 25ft extra fast sinking head with a handling line. The line also includes SONAR sinking technology which uses a mix of tungsten and tapering styles for helping your flies get down.

The AST slickness additive helps the line shoot farther through the guides and sheds dirt and algae with ease for better durability, The braided multi-filament core gives the line superior strength and increased durability.

The line has welded loops which are exceptionally slick and strong and enables quicker connections between fly line and leaders or fly line and backing.

The Scientific Anglers Sonar Sink 25 Fly Line is available in various weights for you to choose from.
