Sci Angler Sonar Saltwater Intermediate Fly Line
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.

Fished it on the flats during low tide and noticed the clear head kept the flies hidden. Redfish took the flies without showing interest at first, which was a big plus. The sink rate was consistent and felt smooth in the water.

Used it for bonefish fishing in shallow waters. The slow sink helped keep the flies just below the surface. Not as flashy as other lines, but the stealth worked well for the species I was targeting.
Theresa Mathis –
Great for tarpon fishing in warm saltwater. The Tropi-Core tech held up well in the heat. The line didn’t snag and the sink rate was exactly what I needed for intermediate presentations.
