Thought this might be an interesting thread to add to the DIY forum, someone can move if otherwise.
Here is my first attempt at filming underwater, bringing a striper to the boat. This is filmed in 1080P, edited and saved in HD. I think the field of view was medium, should change to wide next time. Thanks Niko for hooking and holding the fish nearby.
1. I routinely mount my GoPro "upside down" and there is an image orientation option in the menus. Setting this preference on the camera saves HOURS of imaging flipping on the computer.
2. I bought a telescoping pole ($20 Quikpod QPAK-COMPOD Compod Slim Extendable Handheld Tripod off Amazon) which you attach the camera and use to plunge into the water. I am not necessarily recommending this one there are many from which to choose. If your boat has high gunnels you will definitely want one with a longer extension range than this one.
I also tried to film some pods/schools of sand eels but saw nothing on the video, Note to self: point camera down more, looking up from below at the surface is very uninteresting.
