The DJI Wireless Thumb Controller for Ronin and Ronin-M allows one-man operation of Ronin gimbals so that you can hold onto the gimbal while still controlling the camera. It has a wireless range of up to 200' and easily clamps onto the Ronin's handlebars. The pressure-sensitive stick allows you to change settings, speed, and direction of your gimbal all at the flick of your thumb. It is compatible with all Ronin gimbal stabilizers.
