The Moza Underslung Mini Handle for Air 2 Gimbal provides an additional point of balance when you use the gimbal in underslung mode. It attaches to the 3/8"-16 mounting port on the front of the gimbal handle using an included 3/8"-16 thumbscrew. It functions as an additional grip while also providing a shoe mount and 1/4"-20 and 3/8"-16 threaded holes for accessories. When the gimbal is used in underslung mode, the position of the gimbal handle is reversed, so you're able to secure this Mini Handle to the mounting port of the gimbal handle. Alternatively, you can secure it to either the 1/4"-20 or 3/8"-16 mounting port on the bottom of the gimbal handle and use it in other operational modes as well. A knurled 1/4"-20 screw is also included.
