I do some wingfoil video on YouTube with one or more Gopro for various points of view.
I use a Bite mount from Gopro for POV, on the helmet to focus on the wing or on the board. I put also a mount on the board, you can film yourself or film your foil under your board.
I use a fly mount aero wing on the wing to film myself. It's way better than the tracer skymount wing edition because it's lighter and you can move it without unflate your wing.
My last video
I hope my english is understandable
