Scientific Anglers Sonar Leader

Scientific Anglers Sonar Leaders attach to the end of a floating fly line to put your fly at the exact depth you need. Moreover, a welded loop at the butt and a micro-swivel at the tip (Floating excludes swivel) reduce twist and keep casts efficient. Therefore, you can cover everything from the surface film to deep structure with a single reel and line.

Swap densities in seconds and adapt to wind, current and fish behaviour without a full re-rig. Consequently, Sonar Leaders shine on single-handed lines and light double-handed setups. In addition, a printed Line ID makes it easy to grab the right tip. As a result, you’ll fish more effectively across the entire water column.

FEATURES

• Floating and sinking options for single- and light double-handed lines
• Welded loop (butt) and micro-swivel (tip) to minimise twist (no swivel on Floating)
• Printed Line ID for quick density/length identification
• Lengths: 7 ft (2.1 m) and 10 ft (3.0 m)
