The Benro Aero 4 PRO is a travel tripod/monopod that supports up to 8.8 lb (4kg). This super compact video tripod utilizes reverse folding legs, making it small enough to fit inside of a backpack, rolling case or carry on. One of the tripod legs can be removed and combined with the center column to form a full size monopod when necessary. The unique leveling column provides fast and accurate leveling, a necessity to keep your horizons straight and level during horizontal pans. The integrated bubble level assures perfect alignment. Carrying case included. Despite its small size, the S4 PRO is a versatile video head with additional counterbalance. The S4 PRO video head supports up to 8.8 lb./4kg. Equipped with a 60mm flat base with a 3/8"-16 thread, the S4 PRO is a versatile creative tool allowing you to mount the head separately on sliders, jibs, or monopods. Other features include: pan & tilt lock, fixed pan & tilt drag, additional counterbalance (1-2), bubble level and two 1/4"-20 accessory mounts for attaching monitor arms or audio recorders directly to the head. This allows you to attach accessories without needing a cage or rig to do so. Tilt range for the S4 PRO is +90o/-75o. The forward 90 degree tilt helps with table top setups. The S4 PRO also features metal ratchet style knobs and an improved CNC machined aluminum sliding camera plate.
