The Cendence S Remote Controller for Matrice 200 Series V2 from DJI features OcuSync 2.0 technology which is engineered to achieve transmission distances of up to 5 miles. The Cendence S utilizes dual-frequency support to help ensure that video is stable across those distances. With compatible drones, you can pilot alone or use an additional (not included) Cendence S for a dual-controller setup. This mode helps with more complex flying and filming.
