Have you ever heard of a TrollPro? It's an underwater housing for a GoPro that is specifically designed to let you troll the camera behind your boat. I got one last spring, and no less than 6 times this summer I rigged it up and dropped it in various tuna spreads while trolling offshore. You know what I've captured so far? About 3 hours of skirts, cedar plugs, and rigged ballyhoos swimming by their lonesome. Not once not ever has a fish come in on the lure the camera was filming. I wish like crazy the mako footage below was something I shot. Guess I'll just have to keep trying. Have a great weekend.
