I got the idea from seeing a point & shoot camera mounted to an old speargun handle (thanks Nolan!). So I took an Alexander handle off one of my scuba guns (haven't been using those very much) and mounted my GoPro to it. The mount was stuck on to the handle with the stock "sticky pad". Added a lanyard using one of the screw holes in the back of the handle. I was concerned with with the sticky pad failing so I was always checking it but never had any problem. In the near future I'll be modifying this connection so it isn't completely dependent on the sticky pad. I have the lanyard around my left wrist and with one hand I can hold the mount and gun together in such a position that the camera is facing straight down the gun. On my descent I equalize using my right hand and as I approach the bottom I transition the gun into my right hand and use the left to film. I press the record button right before I take my final breathe up. Obviously there is a learning curve to filming and shooting fish at the same time.
