The ultimate clear saltwater line for effortless accuracy, stealth, and distance.
The Scientific Anglers Magnitude Smooth Balance Fly Line sets a new benchmark in saltwater fly line technology, delivering unmatched clarity, shootability, and durability for tropical anglers. Designed for precision at all ranges, the Balance taper excels at both short, accurate presentations and long-distance shots across flats and open water. Featuring DuraCoat dual-polymer technology and EST+ slickness additive, this line is built to handle the rigors of salt, heat, and constant casting—remaining slick, strong, and tangle-free through long days in the sun.
Engineered with Clear Floating Technology (CFT), the Magnitude Smooth Balance Line offers stealthy presentations in gin-clear water, giving anglers the edge when targeting wary bonefish, permit, tarpon, snook, and redfish. The taper design increases in weight as more line is carried in the air, ensuring effortless loading and control for both close-range accuracy and long-distance delivery. Available in two configurations—a fully clear line for ultimate stealth or a light olive line with a 15' clear tip for better visibility—this fly line excels in Floridas waters while still working in waters like Belize and Mexico.
Every component of this line showcases Scientific Anglers’ pursuit of perfection. The DuraCoat construction enhances abrasion resistance and reduces memory, while EST+ keeps the line self-lubricating for continuous slickness and eco-friendly performance. Integrated welded loops provide seamless connections for clean turnover and buoyant transitions, and the SA•ID system ensures quick line identification. Purpose-built for hot climates and saltwater species, the Magnitude Smooth Balance Fly Line blends cutting-edge technology with refined balance—giving anglers complete confidence from the first cast to the last.

Duracoat - Specialized dual-polymer design optimizes line stiffness, slickness, and abrasion resistance while significantly reducing line memory and tangles
EST Plus - Proprietary slickness additive that provides unmatched durability, smoother shooting, and eco friendly performance. Lines with EST+ are self lubricating, as you use them the additive seeps out in small amounts keeping the line lubricated.
CFT (Clear Floating Technology) - CFT uses naturally buoyant polymers for the ultimate in stealthy presentation and best-in-class durability.
Welded Loops - Exceptionally slick and strong, Scientific Anglers' Welded Loops produce smoother casts and easier turnover with a seamless fly-line-to-loop transition, making for softer landings and cleaner pickups. The sleek design also maintains buoyancy for improved fly-line flotation and enables quicker connections between fly line and leaders or fly line and backing.
SA Line ID - Meet the Scientific Anglers Line Identification System. SA•ID is an innovative line-marking system allowing you to identify your lines at a glance. Wonder if a shooting head is 200 grain or a 300? Just look at the SA•ID. The SA•ID can be found on the first 1-2 feet of the tip section of your line.
