The Zenmuse H3-3D Video Output connection Cable provides an essential connection between the GoPro camera and H3-3D gimbal. It allows the video signal from the camera to be relayed through the gimbal hardware for connection to a video transmitter, whether for FPV (first-person view) or live monitoring applications. This part will serve as a replacement in case the original gets damaged and can be useful to keep on hand as a spare.
