Currently, there is no accurate way to predict underwater ocean visibility conditions. This leaves SCUBA divers, snorkelers, free divers and marine researchers always guessing at what the conditions might be, which wastes time, effort and money when they inevitably guess incorrectly. VizNet’s goal was to solve this problem by developing a solar powered, self-sustaining marine buoy which can directly measure and upload real-time ocean visibility conditions to the internet. This is accomplished with a turbidity sensor specially calibrated to ocean diving conditions. This product allows divers and researchers to check the conditions before they go out, removing the frustration out of the dive planning experience and allowing them to get the most out of their dives.
