You'll never have to worry about tangled cords again. With the Wireless WaveBird Controller and the Wireless Receiver, you can play from up to 20 feet away! The WaveBird uses RF technology that allows you to play Nintendo GameCube from anywhere in the room, without wires and without having to be directly in front of an infrared receiver.
The same size as the standard GameCube controller, the WaveBird has a slightly extended lower end to accommodate two AA batteries that provide more than 100 gameplay hours of wireless control. The RF standard enables the wireless connection to stand true—even under the covers or behind a wall. With 16 different channels to choose from, four WaveBirds easily can hook up to a single machine, enabling a totally cordless multiplayer experience
