Fly Line Features

Crazed, fishing fools? Line geeks? GUILTY AS CHARGED

Some say we are just fanatics, using our selfish needs to create the most sophisticated, strenuously tested products available... but we call it pride... pride in the promise to give you the absolute, hands-down, best of fly fishing excellence on your rod. RIO is fanatical about technology. And our cast members have donated literally thousands and thousands of hours on the water researching, designing and refining our products. All with one goal in mind – helping anlgers hook, land and turn loose more fish!

Density Compensation

The majority of modern fly lines feature a taper at the front end, which ensures that they cast smoothly and land on the water without too much impact. With sinking lines and sink tips, this taper creates a small problem; as the line gets thinner the amount of coating on it gets less.

The coating is what makes a fly line sink, so as the coating is reduced, the sink rate slows down. Usually this means a tapered sinking line sinks in a curve - with the thicker, heavier and denser body section sinking faster than the tip - not good for controlling the depth, and especially not good for detecting atake, or setting the hook.

RIO's Density Compensation adds a more dense material to the thin tip, which ensures the line sinks straight - better for knowing when a fish takes the fly, and far better for setting the hook. All RIO's premium tapered sinking lines and sink tips are Density Compensated.

DualTone

DualTone is a system perfected by RIO that marks the sweet spot of a fly line by providing an obvious color change in the line. The design of every fly line taper, its most likely application and each individual line size is carefully taken into account, and the location of the color change is unique to each fly line.

Every line model and size is tested on a selection of fly rods to find the ideal place where the rod loads, and the color change starts at that point.

With the DualTone system it is easy to see how much line to strip in, where to pick up a cast, how much line can be held in the air when false casting, and when to make the final cast.

Hang Marker

A highly visible, short mark built into the fly line that shows anglers when the end of the sinking line is getting close during the retrieve. For anglers that fish the “hang” this is invaluable.

Easy ID Loops

Easy ID loops are neat, printed loops that show the size and type of the shooting head.

Loading Point

An easy to see reference point that shows the most efficient loading point of the fly line.

Front Welded Loop

A neat, bullet-proof welded loop on the front end for fast rigging.

Back Welded Loop

A neat, bullet-proof welded loop on the rear end for fast rigging.
