Overview

A COMPLETE SERIES OF SINKING LINES DESIGNED For Easy Distance And Complete Fly Control

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

Overall rating: 5.0 / 5 from 25 reviews.

Reviews

New lines seem lighter and slick

"No line casts like the original Rio Deep 6 but these are nice lines. Recommend going up a line weight if you are throwing 100 feet plus. I'm now using the 6 wt on my 4 wt as 5 was too light but I use strong very fast rods."

— Jeff (5/5)

Cracking lines.

"I’m hoping that the life of the Rio lines has improved. They seem to crack very quickly. They cast great up until they crack. After that they begin to sink quickly"
