The Hanak ECO+ tungsten jig head directly correlates diameter and weight, and comes in silver. Silver pairs particularly well with gray, black, white, or pearlescent jig bodies and gives a cooler appearance than gold. Sizes range from 2.30 to 3.80 mm and from 0.11 to 0.39 g; packaging: 50 pieces per bag. In shallow water, start with the lighter weights; increase the diameter and weight when the current or depth requires it.
