The RIO® Lake Aqualux Intermediate is a must-have line for the serious lake angler. Castability has always been a problem with clear intermediate sinking lines because there are no lubricants in the coating and the lines drag through the guides. RIO has solved the problem by incorporating proprietary lubricants into the running line coating that make the line slick. The running line is translucent green while the head is completely clear. With an intermediate sinking rate of 1.5 – 2.0 inches per second (3.7 cm/s), the line is perfect for fishing subsurface and shallow shore lines. Ideal when stealth is required for wary, selective fish. Made on a low memory supple monofilament core with a coldwater coating. This line will enable you to fish shallow water easily when fish are patrolling the edges of a lake. The Rio AquaLux Fly Line has less memory when cold than do most other sinking fly line, which makes it easier to cast then the weather/water are cold during the early season.
