Rio Indicator Fly Line

The Rio Indicator Fly Line was designed ro the specific application of casting indicator rigs with ease – whether for trout or steelhead. The thick diameter, high visible tip can be used as an indicator – especially when Czech nymphing and combined with the short front taper, easily turns over the largest of indicators with exceptional ease. The ultra long head and back taper make it very easy to mend and control the way the fly fishes at great distance. The line is manufactured with Rio’s latest high tech coating; XS Technology for super slick, dirt repelling coating, AgentX for an ultra smooth surface and high floating running line for Super Floatation Technology that creates a high floating tip that will not sink. The line also features Rio’s DualTone color concept to easily show the angler the perfect loading point for each line size. A welded loop on both ends makes for easy rigging and fast leader changes.


Delicate Presentation

XS Technology - XS (Extreme Slickness) Technology began when RIO's chemists began reformulating conventional chemical combinations. Although RIO's formulas were great, our scientists are fly fishers, and by definition they want an even slicker fly line - it's just part of the deal. So first, they tackled the polyvinyl chloride (PVC) coating and through intense scrutiny down to the polymeric mix level, (say that 10 times fast) they defined some fundamental limitations. Out went the old PVC/silicone formulas and by methodically adding a little more of this, a little less of that, and a pinch of secret sauce, the lab coats cooked up a completely new and improved recipe.

AgentX Technology - We've all wanted a higher floating line for a long time but, even as remarkable as our fly lines are, they can't float without a little technological intervention. Traditionally, getting a line to float has required mixing a bunch of tiny glass balls (called microspheres) into the soupy coating compound prior to the curing phase. The higher you want your line to float, the more glass balls you must add. But this creates a problem in that the microspheres can create a rougher, microscopically abrasive coating that has less plastisol which results in a structurally weaker fly line that cracks.

So, after years of experimenting with exotic compounds and plenty of waist-deep R&D, our lab people discovered an element far more buoyant than the rest of the industry. But the right element was just the start. It took an exponential leap in rethinking the manufacturing process to put it all together. AgentX is a result of the combination of a highly buoyant undercoat coupled with a super-smooth outer coating, and it produces the smoothest, most durable, and highest floating fly lines imaginable.

SFT Technology - A customer survey performed by RIO showed that the number one complaint for fly lines was that the tip sank. RIO's chemists deduced that if one coating of AgentX was so buoyant, then two coats must be, well, really buoyant, and the end result is SFT - Super Floatation Technology. Simply put, this is a manufacturing technique that allows us to fuse two layers of buoyant AgentX coating together. This specialized process is applied to the front few feet of the fly line, producing a tip with a specific gravity of around 0.70. Compare that to the standard s. g. of 0.88 on regular fly lines and you get an idea of just how significant this is.

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.
