Like others have said, I used mine a lot when I first got it, but that has tailed off. To do it right takes a lot of work filming it so you have interesting footage and editing. So it can take a little away from whatever activity you are doing, like fishing. It also helps if it isn’t just one person doing all the work.
If you ever plan on sharing I suggest just studying other people YouTube videos. I like well edited and short videos. I have a hard time watching peoples videos where they are trying to make it an episode.
I bought a Okuma Nomad Camera Stick which is good for getting different perspectives and staying dry getting underwater footage. I need to buy a chest harness. What sucks is if you bring the GoPro and try getting filler shots and different angles, but then the fishing is slow, you wasted time.
I think anyone planning on doing a YouTube channel/video should own a good drone. I never get tired of watching footage from a drone.
