It's not usually the footage of epic catches that have instructional value. It's in the down times between fish where you'll often pick up on personal technique flaws. For example, if you miss several fish, you can analyze the rod angle and note mistakes prior to the hook set. Or if your casting is not spot-on, there's a good chance you can detect a fault in your arm angle or release. That stuff won't make the highlight reel, but it's valuable information. I mount my camera on a chest harness, and though the footage may still be a little shaky, it's not nearly as bad as a head mount, as your torso moves a lot less.
