The Leofoto YB-75LC Leveling Bases with Lever Release Clamp for 75mm Bowls with Long Arm and Hook can be used in combination with a Leofoto tripod where the platform between the legs can be removed. For example, the Summit tripod series will be perfect for this unit as it has a 75mm bowl diameter, the YB-75 can be used with any other tripod with a 75mm bowl diameter as well.

The YB-75LC additionally features an Arca-Swiss quick release clamp, so you can attach a camera directly with a quick release plate to the levelling base.
You can use the hook on the Leofoto YB-75LC Leveling Bases with Lever Release Clamp for 75mm Bowls with Long Arm and Hook to hang a weight or bag. The handle can be used to level the video head.
There is also a bubble level built-in to see if the camera is straight.
