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!

Line loop...Not me! ( had to be the line)


I just purchased tatsu 6lb..every three cast.. line would loop..I reloaded same result....I would like to say after contacting a tatsu consultant..with proper instructions on loading line /swivel line to a post..walk off half a spool...results I walleye at nite ..this line is finesse casting has improved 50%

Worth it!


Bought 10# to fully spool a baitcaster for chatterbaits, crankbaits, jertkbaits, etc.--glad I did!

Strong & supple

by -

Very supple line with little memory. In three days fishing with ultralight spinning reel loaded with 6lb. test, only had one time when a loop formed at the front of the spool. Normally with mono, I could have expected several loops to form per day while casting light lures into the wind.

Useed for ice fishing

Using for ice fishing. Low memory. Very flexible easy to use.

I used Nanofil for light lure fishing for bream in Australia's souther estuaries. It is soft, supple and casts further than any other superline I have used.
