Scientific Anglers Sonar Custom Tip Fly Line

Part Number: LINE-SACUST

Surf/Dark Gray

This Sonar series line from Scientific Anglers was made for custom cutting the tip so you can match the line to your exact sink-tip needs. The sink-tip section sinks at 7.75 inches per second - it gets down where it needs to go and stays there. This custom tip line is capable of achieving 7 through 15wt rod sizes - a super sweet line for those looking to get precise. Check out the chart to help guide you to the right custom cut length.

  • Cut-to-fit design lets you cut the tip to the ideal weight for your fly rod
  • Goes deep and stays deep
  • Intermediate running line
  • Sink Rate: 7.75 ips
  • Braided multifilament core
