About this unit

The GoPro HERO9 Black is a waterproof action camera with a 23.6MP sensor that records up to 5K30 video and 20MP stills, with HyperSmooth 3.0 stabilisation and in-camera horizon levelling. It was the first HERO to add a 1.4-inch front-facing colour display alongside a larger 2.3-inch rear touchscreen, and it is waterproof to 33 ft without a housing. It uses a removable 1720mAh battery and supports 1080p live streaming and webcam mode; on a used camera, check the lens cover for scratches, the door seals, and battery health.
