Abstract: Fishing with natural bait action is achieved by using a very light line leader attached to the hook, and fortifying it by transfer to a heavy line after the fish is hooked. The mechanism for doing this is a rotatable spool upon which a length of light line and a length of heavy line is wound in opposite directions so that unwinding heavy line (attached to a pole) from the spool will wind up the light line extended for fishing. A short length of heavy line near the hook will thus be wound on the spool for landing a fish with the heavy line. For casting, the spool is covered with a rubber-like membrane through which the heavy line is passed. A slit in the membrane provides enough friction with a knot in the heavy line to retain the length of heavy line spooled up until a fish is caught.
