How do I film them? Tripod with one of those trackers?
Yes. I use SoloShot3 Optic65
The system uses GPG "tag" worn on my arm.
The GPS satellites tell the Camera where the "tag" is, and the camera films that signal location.
The video quality is great, when everything works correctly.
It doesn't follow correctly all the time, but it is the only option, if you want a "follow me" type of camera.
I lug all the gear, board and paddle to the beach, set it up and wait till it starts following.
Then, hope no one steals the camera while I'm surfing

I film every session I can, but many of my favorite point and reef breaks are accessible only by a long paddle... so "Kook Hat Cam" gets the gig.
