By using fluorocarbon that is highly abrasion resistant and durable, you can attack the points of concern with nylon. Unlike nylon, the transparent refractive index of light is very close to water, so it is difficult to see in water and does not leave your Aolica alert. Especially during daytime fishing. High Specific Gravity (1.78) sinks quickly and fits well to the tide, so you can find a wide range of layers, and quickly send the agi to the best swimming layer of the moment. The color of the line is a basic yen insertion point, which is shallow 65.6 ft (20 m) to make it easy to handle deep, so it is possible to change between natural and blue. ■Line color: every 25m Natural → Blue ■Specific Gravity: 1.78
