Helios 3D 4-Weight, 9-Foot Fly Rods are designed for exceptional accuracy but with enhanced power. They are the most accurate fly rods ever built, but offer remarkable strength and the ability to place a fly where you want it at distance. The Helios 3D 904-4 offers superb accuracy at distance with the ability to put a streamer in the sweet spot of a cut bank at 50 feet. Covering big rivers and still water with uncanny precision is just what this rod was designed to do. The fish are not just out of reach anymore. No cast ever thrown is identical to any other cast ever thrown. The variables of caster, rod, and conditions are too great. Helios 3D was designed to significantly reduce the variables at the point of release focusing the energy of the cast to the intended target. No matter what happens behind you, the energy of the forward cast is crisply released through a tight window created by the most significant reduction in horizontal and vertical tip frequency ever conceived. It is a rifle in a world of muskets and it autocorrects the variables of the cast to the target with incomparable precision.
