I noticed that the GoPro 8 Black has dropped tremendously in price both new and used, this is the refurbished price if you check it out on Amazon, super cheap considering this action camera comes with that new hymersmooth 2.0 which could drastically reduce any shaking or vibration from the brand of underwater drone you own. Just something also to consider if you're not happy with the video quality on your ROV. Just got to be careful where you position the action cam, if you put it too far in front, it could put stress on the motors and throw off the weight distribution. Best to mount it somewhere in the center I'd say. Worth a try if you're unhappy with your video quality!
