The Scientific Anglers Sonar Titan Sink Tip Type S3 – WF6F/S3 (Product 131995) is a high-performance fly line designed for anglers targeting fish in deeper water or strong currents. Here’s a detailed breakdown of its features:
Key Features:
1. Sink Rate (Type S3):
– Sinks at ~3 inches per second (IPS), making it ideal for intermediate-depth presentations.
– Perfect for swinging streamers, nymphing, or fishing in moderate currents where controlled depth is crucial.
2. Weight-Forward (WF6F) Design:
– WF6F indicates a Weight-Forward 6-weight floating head paired with the sink tip.

– The floating section aids in mending and line control, while the sinking tip gets flies down efficiently.
3. Sonar Titan Technology:
– Features ultra-low stretch core for solid hooksets at depth.
– Aggressive taper for tight loops and turnover of larger flies.
– Durable coating resistant to abrasion and cold-water cracking.
4. Versatility:
– Great for trout, bass, steelhead, and salmon in rivers or lakes.
– Effective in swinging flies, stripping streamers, or nymphing where depth control matters.
5. Line Specifications:
– Total Length: ~90 ft (varies by model).
– Head Length: ~38 ft (floating section + sink tip).
– Sink Tip Length: Typically ~10 ft (varies by model).
Best Use Cases:
– Streamer Fishing: Excellent for stripping Woolly Buggers, Sculpins, or baitfish patterns.
– Nymphing: Gets weighted flies down without excessive split shot.
– Moderate Currents: Ideal for rivers where a controlled sink rate is needed.
Alternatives/Comparisons:
– Faster Sink: Consider Sonar Titan S5/S7 (5-7 IPS) for deeper pools.
– Full Floating: SA Amplitude Smooth Infinity for dry flies.
Pro Tip:
Pair this line with a 6-7 wt rod and a 7.5-9 ft leader (depending on fly size) for optimal performance.
