This is one of the early videos I shot using a GoPro mounted on a stabilizing fin and lowered into the water with a fishing rod. This Floridian shipwreck is located in 170-200ft of water on the east coast (between Port Saint Lucie and Fort Pierce inlet). While this video was originaly intended to promote some of my fishing lures, I was stunned when I reviewed this footage. Even without additional lights, I could clearly see the wreck.
Until I saw this footage, the shipwreck was nothing more than a good fishing set of long/lat coordinates and a red blip on my fishfinder. Now , it became something alive, something with an idendity. This led to my ongoing pursuit of being able to get incredible footage, way beyond a scuba diver's range, even beyond most ROVs. My latest specialized GoPro case has been tested and can go down to 12,000ft (4,000m). We have several other accessories either in prototype mode or on the drawing board.
How this was shot: The GoPro is placed into our patent pending case and stabilizing system. The entire system is attached to a fishing rod with a large capacity reel (50w in this case). The system is then lowered unto the bottom. Since there is no "live feedback", everything is done by feel. When you feel the rod tip relaxing, you know you've hit the sea bottom, When you feel a slight but consistant vibration, you know your fishing line is rubbing against something...(early sign of getting tangled or stuck), etc. It sounds more complicated than it really is. Anyone can develop a "feel" for what the camera is doing in short order. Of course there are limitations. The more line is out, the more subtle these indications will be.
A key point is having a decent fishfinder (sonar) which will allow you to know where you (boat) are in relation to the structure or shipwreck you are trying to film.
The video is a bit jerky since I was trying to get a fish (amberjack in this case ) to bite the lure. Cheers and thank you reading this far!!
