Slow-Sinking Fly Line for Salt Water

It’s not very often you’ll need to fish topwater flies in the salt. That’s where an intermediate line comes in handy. The SONAR Saltwater Intermediate fly line features a slow-sinking clear head that cuts through the surface and provides an amazing amount of stealth for those wary fish cruising the flats. From redfish and bonefish to permit and tarpon, give yourself an edge that fish won’t be able to see.

Slow sink rate gets flies just below the surface
Engineered for use in salt water
Clear for stealthy presentations
Tropi-Core technology for tropical climates
Sink Rate: 1.25 ips (Intermediate)
SA ID – SA SONAR SW INT WF X I (X = line weight)

Herwin Cortez – July 19, 2026

I bought this line on a 10 wt. For my Florida trip in Cocoa Beach this past week. The line held up amazingly in Florida’s July temps. To top it off, it held up well on my first snook that measured 29″ and 20+ lbs.
