The Scientific Anglers Magnitude Trout Lines are a standout innovation in the world of fly fishing, particularly for anglers who demand stealth, performance, and durability in their gear. Designed with cutting-edge technologies and a keen understanding of the needs of modern trout anglers, these lines set a new benchmark in the clear floating line category.
What makes the Magnitude series exceptional is its added stealth, delivered by a clear floating tip that reduces line visibility and helps prevent spooking wary trout in clear water. Unlike many other clear lines that suffer from stiffness or memory issues, these lines remain supple and low-memory even in moderate temperatures (50°F and above). This is a significant benefit for anglers fishing spring through fall.
Where these lines truly shine is in their advanced material engineering. Scientific Anglers has introduced three proprietary technologies that elevate performance:
– This embedded slickness additive not only ensures ultra-smooth shooting but also enhances the durability of the line without compromising its clarity. You can expect consistently long casts and minimal friction through the guides, even after repeated use.
– A dual-polymer coating designed to optimize the line’s stiffness, abrasion resistance, and memory. It gives the Magnitude lines a unique blend of flexibility and toughness, helping them maintain their performance over time without the typical "clouding" effect seen in many clear lines.
– Utilizing naturally buoyant polymers, CFT ensures that despite their clarity, these lines float reliably and maintain a high-riding profile on the water—critical for effective line control and accurate presentations.

We have been wildly fortunate to fish these lines for the past couple of months both locally, and abroad. Needless to say we have been super impressed with the quality and performance of these lines. With applications ranging from New Zealand to Flat Creek, this line will be a staple in our quiver for technical trout fishing.
Final Verdict:
The Scientific Anglers Magnitude Trout Line is not just another clear line—it’s a meticulously engineered tool that brings serious innovation to the trout angler’s arsenal. If you value stealth, slickness, and longevity in a floating line, the Magnitude series deserves a place on your reel.
