Last ten years I've been working on a project photographing animals with an underwater polecam system. Today there are no great polecam solutions you can buy, so I ended up designing my gear with 3D modeling and 3D printing. Many prototypes have been tested in rough conditions in Svalbard and Antarctica. The polecam is a great tool when I want to photograph below the surface and don't want or can't get into the water myself with a dry suit, especially in Polar regions.
