I recently acquired a couple of GoPro cameras and would like to be able to attach it to my fishing line while in the water. Now, I've searched YouTube and have seen 100 videos of people showing this type of footage, however, I can't seem to find a video or website with instructions on how to do the attaching of the camera to the line. I figure it has to be tethered by a separate line, something much thicker as not to lose the camera, but from there, how do you keep it attached to the main line so it's always pointing towards the hook?

If anyone has any experience with doing this or maybe you've found a video or website showing this, please do share with it me! I'm anxious to try this out while drift fishing in my kayak come January!
