RIO's Fathom fly 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 to stop stripping, and when to fish the “hang”, and features RIO’s “Density Compensation” (except type 7) for complete fly control.

Noted Features:

• Hang Marker shows where to fish “The Hang”  
• Density Compensation for complete depth control  
• Built on a supple core that will not tangle
• Easy casting, fast loading head for minimum false casts and quick distance
