The drop back bung completely revolutionises small stillwater indicator fishing, particularly on challenging days with light winds & pressured fish. At times an increase in hittable takes in the region of 40-60% over standard indicators, is possible. The drop back, cast's better, strikes easier and converts more takes than a standard indicator. Each Drop Back Bung is marked with black dots on both the Yellow and the Red (Orange) section of the bung. To properly load / cock the bung, so that it fishes as intended tie on the appropriate number of Croston Flies marked with either a Red or Yellow dot. So, to load the Medium Bung correctly, you need to rig up one fly with a Red dot OR two flies with Yellow Dots.
