Just thought I share a little clip I made while foiling with me new Insta 360 1R. Best to watch in full screen so you can zoom out more for best view.
I really like the point of view harness mount gives you and the fact that Insta can be without a case is good. I tried with a dive case and the dive case pretty much makes it useless as it blocks you completely.
I am using a harness mount and insta without any dive case.
