Scientific Anglers Sonar Titan Pelagic
The Sonar Titan Pelagic is built for offshore fly anglers targeting true big game — the fish that live deep and hit hard. Designed to get large flies down quickly and stay there, this fast-sinking line is made for pursuits like marlin, tuna, GT, and other powerful pelagic species.
With a Sink 6 head (6.0+ ips) paired to an intermediate running line, the Titan Pelagic reaches depth efficiently while maintaining control during the retrieve. The short, powerful head and compact front taper load quickly and turn over the largest flies with authority — critical when casting heavy baitfish patterns in offshore conditions.
Built on a 65 lb. Tropi-Core monofilament core, this line is engineered for strength and performance in hot, tropical environments where failure is not an option.

FAQ
What makes the Sonar Titan Pelagic suitable for deep-water fly fishing?
The Sink 6 head provides a fast sink rate of 6.0+ inches per second, allowing large flies to reach deep water quickly. Combined with a compact front taper, it maintains control and loads efficiently during retrieval, ideal for offshore conditions.
Is this line durable in hot, tropical climates?
Yes, the 65 lb Tropi-Core monofilament core is specifically engineered for strength and performance in hot, tropical environments where durability is essential.
Can the Sonar Titan Pelagic handle heavy baitfish patterns?
Yes, its short, powerful head and compact taper allow it to load quickly and turn over large flies with authority, making it effective for casting heavy baitfish patterns.



Madeleine James –
Used this line during a marlin fishing trip in the Caribbean. It sank quickly and stayed put in deep water. The fly loaded well and felt solid under pressure. Great for offshore fly fishing with heavy patterns.
Joe Grant –
Felt very reliable in hot weather. The sink rate was consistent and the line didn’t break under stress. Perfect for targeting tuna and GT in deep water.
Wanda White –
Good performance in offshore conditions. Sank fast and handled large flies well. A bit stiff when first cast, but settled into a smooth retrieve after a few minutes.
Gabrielle Marshall –
Highly recommended for deep-water fly fishing. The Tropi-Core core held up well in tropical heat and maintained strength throughout the day.
Benjamin McDonald –
Works well with heavy fly patterns. Sinking rate is fast and predictable. A bit expensive, but performance justifies the cost for serious offshore anglers.
