Tracking line

During fly fishing, the fisherman can judge the water flow according to the light color of about 1m at the slightly end of the fly fishing line, timely adjust the included angle between the throwing direction and the target fish, and make the hair hook easier to approach the target fish through the water flow and take-up action. Because the swimming direction of the fish when biting is uncertain, it is easier to control the fish through hand feeling and bright color points.
