A:AnswerMost mounts and accessories that connect to the GoPro will work on both the HERO8 and the HERO9 models. However, because the two models have different shapes and sizes, accessories like this housing that enclose the GoPro will not work between the models. You'll want to get a housing made specifically for your GoPro.
A:AnswerYes, if you have the HERO8 Black in the full protective housing, there will be that barrier between the microphones and the source of the audio, so there will likely be some affect on the audio quality when the camera is in the housing.
A:AnswerThe skeleton backdoor has an open panel, so it does not provide any additional water depth protection. With the solid backdoor, the Protective Housing provides protection down to 196 feet.
A:AnswerThe Protective Housing does not float the GoPro, and once the GoPro is in the Protective Housing, it will not fit in the Floaty mount. The Handler mount is a good option to use in this type of setup if you're looking for a handheld option.
A:AnswerThe HERO5 Black has a slightly different size and shape than the HERO8 Black does, so this housing won't be a fit. Instead, look for the GoPro Super Suit to use with the HERO5 Black.
