Well that video is quite disappointing.
At least from a surfing standpoint the stabilisation when mounted on the board looks pretty bad. I just shot some footage with the Hero 6 yesterday, and the stabilisation is better. Also the video quality of the REVL looks mediocre in this test video.
This is the footage from yesterday. The Go Pro is mounted on the nose of a 138L SUP Board. You can hear from the audio when the board bounces, and you barely see any movement, whereas on the review video you can see quite a bit of shake. I was hoping that the REVL would be much better.
Also, the camera looks quite big (or the guys hands are super small) which is not a great thing.
They need to have a kiter review it. I want to see the review of the REVL working in a linemount. If that really works, that would be it's saving feature, but that last review is major "putoff" .
The app looks nice and easy to use though.
