Giovanni, you hit the nail square on the head!
We use a "Bazooka Bob" for the job of plumbing up columns during steel erection. It consists of an extendable aluminum tube with the plumb bob enclosed within the 10 foot tube to protect it from the wind. There is no need for a bucket of water or light oil. However, when plumbing multiple stories, the plumb bob and bucket of water works very nicely.
The “Bazooka Bob” is manufactured in Pennsylvania if I remember correctly.
Best regards - Al
