Use the Jigging JawJacker Base to turn your JawJacker into a Jigging JawJacker.? To do this fold the legs up on your JawJacker (not included and sold separately) and slide the hole that runs through the bottom of the JawJacker onto the pivot pin on the Jigging Base.? This will connect the JawJacker and Jigging base together and the JawJacker will teeter totter back and forth on the pin.? Now drop your bait down the hole to the depth you want, put your rod in the rod holder, and set the JawJacker.? Turn the switch on and the jigging wheel on the back of the Jigging Base will turn and move the JawJacker up and down and jig your bait for hours.? When a fish bites the moving bait the Jigging JawJacker will set the hook.? The Jigging Base will fit all JawJackers that have ever been produced.? The Jigging Base runs off of 3 AA batteries and has a long battery life in the cold.? With temperatures ranging from -15 to 5 degrees Fahrenheit (-25 to ? 15 Celcius) the Jigging JawJacker will run for more than 24 hours straight.? With temperatures ranging between 3 and 7 degrees Fahrenheit (-16 to -13 degrees Celcius) the Jigging JawJacker will run for more than 30 hours straight.? Run times keep increasing as the temperatures get warmer.? The Jigging Base comes with 3 jigging wheels, a carrying bag, and a spring.? With 3 different jigging wheels you can match the jigging pattern to the type of lure you are using and how the fish are biting that day.? The wheel with the smallest jigging pattern will just wiggle your bait and the wheel with the largest jigging pattern will jig the bait up to 8 inches.? A spring is included that attaches to the nose of the jigging base.? Sometimes when using longer rods (like the 35 inch JawJacker rod) and heavier baits the weight of the JawJacker is more forward so it doesn?t fall back and rest upon the jigging wheel.? In these situations you can use the spring to push the JawJacker back so it rests on the jigging wheel and jigs smoothly.? The JawJacker and Jigging Base fold up and fit together.? The carrying bag will fit the JawJacker, Jigging Base, jigging wheels, and any extra batteries you have.? With the Jigging Base, now you can add some motion to your bait to help bring in the big ones and catch more fish.
