The Scientific Anglers Magnitude Smooth Grand Slam Fly Line is ushering in a new era in saltwater fly line technology. Headaches with clear lines are a thing of the past. Our new family is loaded with revolutionary technologies, making it the most durable and slickest clear floating fly line on the market. Period.

• DuraCoat leverages an 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 durability, smoother shooting, and eco-friendly performance.
• Using naturally buoyant polymers, we've created the next generation of clear floating lines. With the option of a 10-foot clear floating tip that allows the angler to track the fly and a full clear floating line for the ultimate stealthy presentation.
• Loads rods quickly, cuts through the wind with ease, and turns over big saltwater flies.
• Overweighted by 0.75 sizes to load rods quickly; use the designated line weight for your rod.
• Short, powerful head for quick casts to moving targets.
