RIO Premier Fathom Sinking Lines - Fathom 6



RIO's Premier Fathom 6 Sinking Line is a density compensated full sinking line with a sink rate of 6 inches per second, that now features RIO's SlickCast technology. RIO Premier Fathom 6 Sinking Lines feature a powerful 35-foot head that loads the rod quickly for easy casting and quickly setting you up for long casts.  Welded loops on the front and back of the line allow anglers to change leaders or attach the line to backing with minimal knotsA monofilament core in the Fathom Sinking Lines results in supple line that has just the right amount of rigidity to reduce tangling while casting and fishing.  The Fathom Sinking line family also utilizes a "hang marker" that shows anglers when the line is coming to the end, or when to fish the "hang".  The hang marker also has the lines information imprinted on it for quick line identification.
