Scientific Anglers SONAR Titan Taper Intermediate Sink Tip
The Scientific Anglers SONAR Titan Taper Intermediate Sink Tip is a streamer line for fishing just below the surface. It uses the Titan taper profile to load quickly and turn over large flies, with an intermediate sink tip that keeps your fly in the upper water column where actively feeding fish hold. Works from a boat or while wading for trout, smallmouth, pike, steelhead, or salmon.
Best For
Streamer Fishing - Subsurface - This line handles streamers at fish holding just under the surface. The intermediate sink tip gets your fly down past the film without dropping all the way to the riverbed, which matters when fish are feeding on baitfish or leeches in the upper column. The Titan taper's short, powerful head turns over articulated patterns, bulky deceivers, and heavy dumbbell-eyed flies.
On a fall day swinging sculpin patterns through a tailout where steelhead stage, you need the fly riding a foot or two under the surface on a steady swing, not skating on top and not bouncing rocks. It also works on stillwater when stripping woolly buggers or baitfish patterns over weed beds, keeping you in the strike zone without constant snagging.
Temperature / Conditions
This line is designed for moderate and cold climates. The coating stays supple in cooler water and air temps, and the braided multifilament core maintains consistent performance when things get chilly. If you are fishing tropical or warm-water flats, this is not the line for the job. Use it in cool-to-cold conditions for best performance.
Taper / Weight / Design
The Titan taper is a short, front-loaded head designed for turning over big, wind-resistant flies at distance. This line is built two full line sizes heavy, so a 6-weight loads like an 8. Use your rod's designated line weight and let the extra grain weight do the work. The sink tip section runs between 8 and 16 feet depending on line weight, giving you enough sinking length without creating an awkward hinge point between floating belly and tip.
Features
Intermediate Sink Tip - The sink tip on this line falls in the intermediate range, settling your fly just below the surface at a controlled, subtle rate. Use this when fish are feeding shallow or when you need to swing flies through a run without getting hung up on structure.
Titan Taper Profile - The short, aggressive head loads rods quickly, even at shorter casting distances, and drives big streamers through wind.
Two Sizes Heavy - Carrying two extra line sizes worth of grain weight means faster loading and more energy transfer on the cast. Match the line weight printed on your rod and fish it.
Braided Multifilament Core - The braided core provides a supple, low-memory feel that helps the line lay out straight and shoot cleanly through the guides. It handles cold temperatures well and resists coiling in cooler conditions.
