Scientific Anglers offers the most advanced technology in fly-line manufacturing

Throughout our history, our superior chemistry has provided unmatched durability, permanent slickness, optimal floatation and sink rates that are unsurpassed in fly fishing.  Our proprietary technologies and designs continue to be ahead of their time—allowing Scientific Anglers to bring you the future of fly fishing today.  The following include some of our break through technologies:


ASTAdvanced Shooting Technology (AST)

Our patented dry slick technology sets the standards for slickness, and AST provides continual line slickness allowing the line to shoot farther as it moves virtually friction-free through the guides. 


Improved Dry Tip Technology

As if our original Dry Tip Technology wasn’t already good enough.  Our team of lab engineers set out to find a formula for the HIGHEST floating, fly line tip section on the market today.


Mastery TexturedMastery Textured

Mastery Textured Series fly lines represent a fusion of out traditional Mastery series and our Sharkskin series. Precisely replicated hemispherical divots, similar to those found on a golf ball’s surface, allow the line to outperform conventional fly lines. 



These proprietary microscopic glass bubbles are added to the coatings of all Scientific Anglers floating fly lines to optimize line floatation by effectively trapping air inside the core and to provide precise control over the density of each line.



SAIDScientific Anglers Line Identification (SA•ID)

As a result of our lab's mission to continually improve our lines, we bring you SA ID. 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.



With cutting-edge angling technology that is revolutionizing the sport, the Sharkskin Series provides the ultimate casting experience.  Sharkskin allows you to cast further with less effort and with less line tangling—elevating your fly-fishing experience to a whole new level.


Streamlined Loops

Exceptionally slick and strong, our welded Streamlined Loops produce smoother casts and easier turnover with a seamless fly-line-to-loop transition making for softer landings and cleaner pickups.


Tropi-Core™ Technology

Tropical environments are not only taxing on the angler but can also be taxing on a fly line.  While too much heat can cause other lines to wilt, lines with Tropi-Core™ technology can withstand the hottest boat decks and warmest water environments.  

TRP (Tactile Reference Point)

Tactial Reference Pont is a non embossed section at the AFTMA 30 foot mark. Allowing you to feel and hear the transition from our textured technologies.


Choosing the right fly line

These days, there is a fly line specifically tailored for the most unique application. Choosing a fly line may at times seem overwhelming. However, following a few basic principles can simplify the process greatly and get us all back to what’s most important – the fishing. Click here to download the pdf.


Taper Diagrams

A fly line has more influence on your cast than any other piece of equipment in your arsenal. That's why choosing the right fly line should not be taken lightly. It can, however, be confusing. We've created a taper chart to simplify the process. Within the chart, you'll find the optimum temperature use, taper specs, and "bottom-line" benefit of each line is highlighted. Print out the charts, use them as a guide.
