Scientific Anglers Frequency Boost Fly Line

Built a half size heavy as an all-around general purpose fly line, the Scientific Anglers Frequency Boost gives you that extra help with your cast.

This floating fly line loads quickly, turns over large dries, nymph rigs and steamers with ease. It features a mid-length head that is perfect for nearly all freshwater applications and is ideal for beginners and intermediates alike!

The line features AST slickness that allows the line to shoot farther as it moves through the guides. It also easily sheds dirt and algae for improved, long lasting durability. The braided multifilament core also further enhances durability and the line’s overall strength.

The Scientific Anglers Frequency Boost Fly Line is available in various weights and colours for you to choose from in our drop down menus.
