I was looking for some infos about vibration when falling on this topic.
In my experience, the bigger diameter the legs are, the better stability you have. So this is why I try to never use the smaller one, starting to deploy my tripod always by the bigger tubes.
I'am using my backpak and suspent it to the hook of extension tube, it add weight, so reduce vibration.
In the same way I try to never use deployed extention tube to get higher, using tripod legs to do it so.
Also take care of witch floor you're on. I allways try to get more than 3-5 m away from tripod and reduce move as scanning.
Trucks, bus, and big vehicle can produce vibration your feet cannot feel but you will "see" them in the pointcloud noise.
Then now you can consider that FARO fixation system really sucks ...
