Scientific Anglers Amplitude Sonar Sink 25 Coldwater Fly Line

Scientific Anglers Amplitude Sonar Sink 25 Coldwater is a fly line from Scientific Anglers. We stock it in weight-forward grain weights, with size codes that include F/S. If you already fish this specific line and need a replacement or an extra spool in a different grain weight, this is the same model name and format we carry.
