Now you don't have to depend on your friends' skills with the camera to get smooth, perfectly framed video of your run. As beautiful as it is functional, the new AirTrakker Pro uses our new Inertia Wheel Drive System (patent pending) to provide momentum that ensures smooth panning action even when the rope goes slack. The AirTrakker Pro incorporates a pair of polished billet aluminum clamps. Once mounted, the clamps never need be removed, allowing the AirTrakker Pro to be reinstalled in seconds, with no adjustments necessary. The AirTrakker Pro will fit all consumer video cameras less than 5" tall.
