Triple-Density Line for Throwing Big Streamers. The SONAR series takes your fly and puts it right in front of the fish. Whether you’re throwing streamers for trout, big flies for muskie, or even fishing stillwaters, we have the perfect sinking line for you. Get down, and stay down, with SONAR. - - Two line sizes heavy for loading quickly and delivering the biggest flies to the furthest targets; use designated line weight for your rod - For use in moderate and cold climates; braided multifilament core - SA SONAR TITAN WF X DENSITY (X = line weight) - Cleaning with soap and water on a cloth removes most of the dirt, but cleaning pads work even better. Properly cleaned, your lines will cast better and last longer, certainly a good trade-off for a couple of minutes of line maintenance. To use the cleaning pad, pinch the pad over the line so that the abrasive, non-foam side touches the line. Pull the fly line through the pad under some tension. Repeat this process until some of the fly line color is visible on the pad. Clean your lines every 2-3 outings, or anytime you think dirt is hindering their performance. The cleaning pads are easy to carry in your vest or tackle bag and can be used anytime, wet or dry. Note that flyline dressing can be used to reduce friction during competition- or practice casting scenarios, but we don’t recommend it for fishing.
