RIO Products RIO Fathom 6 Sinking Line

The RIO FATHOM Fly Line is 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, and 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 and features RIO’s Density Compensation (except type 7) for complete fly control.
