To really add a new dimension include a Cobra Crane Tracking Dolly. Our tripod dolly with track provides to and from or side to side motion that simply has no comparison. The dolly holds the tripod and crane and runs on the included PVC track. It runs on six super smooth high quality skateboard type wheels. These wheels are offset by 90 degrees, so they grab the track and smoothly roll over providing incredibly smooth dolly moves that are amazing to watch in your videos.
