Sci Angler Sonar 3D Custom Tip Fly Line
Combining our custom tip series of fly lines and triple density Sonar technology will keep you in the zone longer. Fly anglers are nothing if not inventive. From splicing together lines to weighing coils on a digital scale, finding the perfect sinking line can be a chore. The SONAR 3D Custom Tip sinking fly line makes all of that much, much easier. This cut-to-fit fly line allows you to slice off as much line as you need to fit everything from a 7-weight through a 15-weight.
- Cut-to-fit design lets you cut the tip to the ideal weight for whichever species you’re chasing
- Excellent custom sinking line for trout, bass, stripers, and stillwater angling
- Goes deep and stays deep
- Intermediate running line; fast-sinking head
- Sink rate optimized for consistent depth performance

I cut the line to match my 9-weight setup for bass fishing. It sinks fast and stays deep without tangles. Much easier than mixing different sections.
Jake North –
Great for stillwater use. The tip cuts cleanly and the sink rate is predictable. I’ve used it for trout and it holds depth well.
Jake Newman –
Cut it down to 7-weight for small streams. The line performs better than standard options and doesn’t drag in the current.
Molly Skinner –
It’s a smart solution for anglers who want to avoid splicing. The sink rate is consistent and the line feels solid in the water.
Stephanie MacDonald –
Used it for stripers in a slow-moving lake. The depth control is excellent and I didn’t have to adjust my casting technique.
