Product title: Manfrotto 755XB MDEVE Aluminum Tripod with Built in 50mm Ball Leveler
Product description: The extremely versatile 755XB MDeVe Aluminum Video Tripod from Manfrotto is ideal for Mini DV camcorders. Made entirely of aluminum, the 755XB has a removable center column with a built-in 50mm levelling ball and bubble spirit level that can easily be fitted as a lateral arm. Not only does this allow the camera to be offset from the leg position, it is also the simplest way to shoot a subject from directly overhead. The 755XB's unique center column construction and precision-machined red anodized aluminum allows the leveling ball to be locked by a detachable rotating grip built at the bottom of the center column. This allows the camera operator to level the camera and even adjust its height without needing to make micro adjustments to each individual tripod legs. Replaces item # 755B
