Scientific Anglers Sonar Sink 25 Coldwater S3 150 GR

The Sonar Sink 25 Coldwater features a 25-foot fast-sinking head with an intermediate running line for quick depth control and smooth turnover. Built for coldwater performance, it stays supple and tangle-free even in low temperatures. Offered in grain weights from 150 to 350, this line casts streamers, articulated flies, and heavy patterns with ease. Finished in Ivory/Dark Green, it balances stealth and visibility while helping anglers target bass, pike, musky, and more.
