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, and a color contrast between the head and the running line to easily show the lines 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 RIOs Density Compensation (except type 7) for complete fly control.

• Easy-casting, fast-loading head for minimum false casts and quick distance
