Scientific Anglers Magnitude Infinity Clear Head Float – Smooth
Magnitude lines are ushering in a new era in fly line technology, headaches with clear lines are a thing of the past. Our new family is loaded with revolutionary new technologies making it the most durable and slickest clear floating fly line on the market. Period.
- Optimized for use above 50F/10C. This line can be fished below those temperatures, but will require stretching by hand to manage coils.
- DuraCoat leverages advanced dual-polymer design to optimize line stiffness, abrasion resistance, and slickness. The core is enveloped by a supple material, promoting minimal memory and strong adhesion, while the outer layer boasts a robust composition that significantly enhances slickness and abrasion resistance.
- Enhanced with EST+ slickness additive for unmatched smoothness and performance.

FAQ
What is the optimal temperature range for using this fly line?
The line is optimized for use above 50F/10C. It can be fished below those temperatures, but will require stretching by hand to manage coils.
What makes this line different from others in its category?
It features DuraCoat technology with a dual-polymer design that improves stiffness, abrasion resistance, and slickness, along with EST+ slickness additive for superior performance.
Is the line suitable for use in cold water conditions?
It can be used in cold water, but it will require manual stretching to manage coil formation.



Colin Johnston –
This line performs exceptionally well in warm conditions. The slickness is noticeable right away and the line doesn’t tangle easily. I’ve used it in several trout streams and it holds up well against brush and rocks.
Angela Forsyth –
The DuraCoat construction feels solid and smooth. It doesn’t snag as much as previous models I’ve tried. Great for long casts and consistent delivery on the water.
Cameron Davies –
Works well above 50F. In slightly cooler water, it does coil a bit and needs a little stretching. Otherwise, the slickness and durability are impressive.
Ella Miller –
I’ve switched from an older clear line and this one feels like a game-changer. The float stays stable and the line slides through the water with minimal resistance.
