The Dual Handle for the Crane-2 Stabilizer from Zhiyun-Tech allows you to perform various gestures with the gimbal, such as top-down and bottom-up, with two-handed operation.
The Zhiyun-Tech Dual Handle is an add-on accessory for the Crane 2 stabilizer that converts it from one-handed operation to a more traditional dual-grip, handlebar style configuration like that of the DJI Ronin-M. This accessory is only for the Zhiyun-Tech Crane-2 and Zhiyun-Tech CRANE 2S Handheld Stabilizer and is not designed to work with other gimbals including earlier versions of the Crane.
