The Wii Remote Nunchuk is the new standard controller for the Wii gaming system. Like the original Wii Remote before it, this new controller utilizes a triple axis accelerometer along with a built-in optical sensor that works in conjunction with the Wii sensor bar. Together this enables the recognition of player movement as well as gives the controller the ability to act as a pointing device used in-game. Yet what really sets the Wii Remote Plus controller apart is its incorporation of additional gyroscope technology. This Nintendo Wii Remote Nunchuk is a secondary set that adds even more innovation to the next generation of gaming. Contoured perfectly to fit a player's hand, Nintendo Wii Remote Nunchuk takes the fun to the next level with the remote control & wired nunchuk of your games!
