I took the Action 2 out on the Kayak mounted on a hat and it worked pretty good.
Some issues:
1. Audio had some instances of like a echo
2. Could not use Mic and USB power at same time, so I just used USB Power and there is some bad wind noise.
(with a light breeze it handled it really well, but when it got really windy it got bad)
3. Some weird fish eye effects where things in the center of the frame look super skinny
5. Had issues with a 256gb sd card it started getting errors after about 3 hours and I had to switch to another card.
The first part of the video is a a hyperlapse and then I turned on the Horizon leveling mode and then switched to 1080p Ultra wide 24fps.
I recorded for 4 hours straight using the external USB power.
At the end of the video there is some low light sunset stuff that looks really good.
