The Waverunner Pulsatron accessory looks identical to the standard Waverunner, but because it is controlled by the Pulsatron, comes with a staggering seven functions. We love the Waverunner any way it comes, but the Pulsatron version exceeds all expectations. (N.B You must either buy or already own a Pulsatron or Mantric controller to use this product)
