The Hanak UV+ tungsten jig head directly correlates diameter and weight, and is available in black and fluorescent UV chartreuse. The chartreuse contrast against the black background provides a very clear visual cue on the head. The UV-reactive finish enhances both the weight and the contrast of the head. Sizes range from 2.30 to 5.50 mm and from 0.06 to 1.30 g; packaging: 15, 10, and 7 pieces per bag, depending on the diameter. First, choose the weight required for the desired depth and current speed, then verify that the diameter fits the hook you’ve selected.
