Power Grip Plus Planer Board ReleaseA line release is the critical link between the downrigger and the fishing rod. If it does not preform properly you will loose both valuable fishing time and fish. The fishing line is gripped between the soft pads with variable release tension attained by moving the line in or out of the jaws. The line release is attached to either the weight or the cable. Patented “tension adjuster” doubles the holding power.
