Rio Indicator Leader 10 ft.- RIO’s indicator leaders have a unique design that is ideal for the indicator fly fisher. A powerful butt section and very short taper, easily turns over all manner of indicators, and a long, level tip section allows flies to sink evenly and quickly. The orange butt section is visible enough to be used as an indicator in its own right. Each leader is 10ft long, and available in 5 sizes from 6X (3.4lb) to 2X (10lb).
