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 line's loading point.
In addition, each line is built with a Hang Marker that shows anglers when it is time to initiate the hang, a technique used at the end of the retrieve to trigger a following fish to take the fly. Incorporating the hang into every cast and retrieve presentation is arguably the best way to improve your catch rate when fly fishing stillwaters.
The Elite Fathom sinking lines features RIO's Density Compensation (except type 7) for complete fly control.
