Rio's Fathom Lines are a series of sinking lines designed specifically for the lake angler. Each line has a short, quick-loading head for minimizing the number of false casts and for quick, easy distance. There is a color contrast between the head and the running line to easily show the line's loading point. In addition, each line is built with a hang marker that shows anglers when to stop stripping and when to fish the hang. It features Rio's density compensation (except type 7) for complete fly control.
