The Osmo Pocket Extension Rod from DJI is like an advanced selfie-stick with a joystick and control buttons for the Osmo Pocket gimbal. It also features a smartphone holder for monitoring. The Extension Rod telescopes to up to 30" in length, enabling you to shoot from many more angles. To control the gimbal from the Extension Rod's multiple control buttons, you can either connect the two using a compatible USB cable or the Osmo Pocket Wireless Module, both sold separately. The Wireless Module attaches to the bottom of the gimbal and establishes a connection over Wi-Fi.
