Well, which ever company that made the camera is going to have all kinda of free advertisement out of it. To withstand the water and weather over 4 years is one thing. To withstand the corrosion by sea water is on a whole other level. When designing a product, if we want the product to withstand salt water immersion, it needs to pass some ridiculous tests, meaning the product sealing has to absolutely sound. I'm curious to see which camera this is.
