S.A. Dacron Backing 30lb x 5000yd Yellow

S.A. Dacron Backing 30lb x 5000yd Yellow from Scientific Anglers is engineered for anglers who demand reliability when the drag is roaring and the bite lasts all afternoon. This backing isn’t just a connector to your fly line—it’s the insurance that a trophy fish stays hooked, even through blistering runs and tough takes.

• Test rating and diameter: 30 lb break strength with a thin 0.024 inch (0.61 mm) diameter, reducing line-to-line friction and maximizing spool capacity.
• Length on the spool: 5000 yards, giving you substantial backing to cover long runs and multiple shots at hard-pighting fish without re-spooling.
• High abrasion resistance: Built to withstand rocky strikes, snaggy structure, and rough water where backing takes the brunt before the fly line ever does.
• Colorfast, high visibility: Bright Yellow is easy to monitor under water and in low light, helping you track tension and backing wear at a glance.
• Specialty colors on request: While Yellow is standard, other colors are available on 5000 yd spools by request for fleet or matching setups.
• Performance edge: The exceptionally thin profile and low friction make this backing ideal for drag-heavy species such as steelhead and bonefish, where every inch of line clarity and smooth release counts.

Ideal for anglers who push their gear on big-water adventures, this backing provides a trustworthy foundation that keeps maximum backing capacity, strong knot-holding strength, and consistent performance when fights go long and intense. With Scientific Anglers backing you can focus on reading the fish and steering the fight, not worrying about backing failure.
