Product Details

By combining extraordinary knot strength and castability, Seaguar Tatsu Fluorocarbon Line is the most technically advanced fluorocarbon line on the planet! Tatsu, Japanese for dragon, uses a double-structure design which fuses two custom resins into one main line. The DSF process creates a tough but soft exterior covering a high-density interior for improved tensile strength and sensitivity. No other competitor can match Seaguar's proprietary extrusion process that releases the power of this uniquely structured line. Seaguar's strongest and softest line, Tatsu is the apex of fluorocarbon line design and performance.


Designed as a mainline for any freshwater or saltwater fishing application, Tatsu Fluorocarbon Line is virtually invisible underwater with great hook setting and knot strength. Fish fierce and unleash the dragon with Seaguar Tatsu Fluorocarbon Line!

    great line for winter fishing. Have used it in the past for big river Brown Trout and Steelhead. My main line with smaller diameter Drennan line as a leader. Strong line, good knots.
