The Hanak Fluo UV+ tungsten jig head directly correlates diameter and weight, and comes in chartreuse. Choose chartreuse for a high-contrast rig, especially with a black or dark olive body. The fluorescent finish reacts to UV light and clearly highlights the head. Sizes range from 2.00 to 6.40 mm and from 0.06 to 2.00 g; packaging: 20, 10, 7, and 5 pieces per bag, depending on the diameter. First, select the diameter-weight combination based on the hook and the drift, then choose the color.
