The Phantom 4 Pro controller integrates an upgraded Lightbridge HD video transmission system that adds 5.8 GHz transmission support. The ability to choose between 2.4Ghz and 5.8Ghz allows pilots to cut through interference and eliminates image lag caused when flying in an area with extensive 2.4Ghz frequency use. This ensures the optimum range of a maximum video transmission of 4.3mi (7km). With this screen, a mobile device is not required, simplifying pre-flight preparations. As the DJI GO app is built into the screen, hardware and software can be fully optimized, further reducing video lag. Integration of an HDMI port, Micro-SD card slot, microphone, embedded loudspeaker, and Wi-Fi connection allow images to be edited inside DJI GO to be shared almost instantly. Lastly, a five-hour battery life makes the Phantom 4 Pro + a complete aerial imaging solution.
