Have cam tripod with spirit level. But its v.hard to get the bubble in the middle. Its always slides one way?
If you get it set and it moves the tripod is not stable, with out seeing it I can only guess what is happening. One of the legs is telescoping, a leg is slipping on the ground, camera is way to heavy for the tripod, some one is kicking a leg when you are not looking to mess with you .....
