Scientific Anglers Sonar Saltwater Intermediate Full Clear WF-10-I – Stealthy Flats Line

Stealthy presentation and depth control

The Sonar Saltwater Intermediate Full Clear line is engineered for stealthy, water-wide presentations on clear flats. Its nearly invisible profile helps your fly move with natural motion and minimal line glare, giving you a subtle edge when patience and precision matter most.

Depth, visibility, and range

With an intermediate sinking rate, the line places flies just beneath the surface for lifelike action while maintaining easy line control. The full clear finish reduces water visibility in bright sun, helping you keep the presentation discreet. Available in WF-7-I through WF-12-I, the line adapts to a variety of rod and reel configurations and casting distances, supporting both long casts and more controlled presentations.

On-water use and target species

Anglers often pursue bonefish, redfish, tarpon, and other wary flats residents. The line blends stealth with durability, delivering smooth performance across long days of fishing and multiple casts, while allowing your fly to move with a natural, subtle drift.

• Full clear design minimizes visibility in bright water for stealthy presentations.
• Intermediate sink rate keeps flies at an approachable depth for subsurface action.
• WF-7-I to WF-12-I range covers a variety of rod setups and casting styles.
• Durable saltwater performance resists wear and maintains smooth casting.

On the water, you may notice the line loading smoothly, mending with ease, and delivering steady control even when conditions tilt toward glare or wind. The result is a more confident, precise presentation that supports natural fly movement across shallow, clear bottoms.

• Stealthy flats presentations
• Subsurface fly action with controlled depth
• Reliable saltwater performance across seasons
• Helpful for bonefish, redfish, and tarpon scenarios

Whether you are drifting a crystal-clear flat for tailing bonefish or working a shallow edge for wary redfish, this line offers a discreet, dependable option that pairs with your favorite rod for a balanced, responsive feel.
