Scientific Anglers Sonar Sink 30 Cold Fly Line


An excellent streamer line for fishing trout. Scientific Anglers’ Sonar Sink 30 Cold Fly Line features an extra-fast sinking head with handling line and sinks 4 ft. to 15 ft. at a rate of 4-8 ips. Low-tangle design for smooth casts and increased shooting distance. Featuring Advanced Shooting Technology – a patented, dry-slick technology that provides continual line slickness, resulting in quick movement. It also sheds dirt, algae and other parasitic drag particles so line casts farther, floats higher and stays cleaner than traditional lines. Slick, durable welded loops produce smooth casts, easy turnover and seamless line-to-loop transition for soft landings and clean pickups. They also maintain buoyancy, improving flotation while enabling quick connections from line to leaders and backing. Scientific Line Identification (SA-ID) offers at-a-glance line recognition. Braided multifilament core works well in cold to moderate water. Replaces Mastery Textured Coastal Express.
