Viziato builds forecasting tools for people who work and play beneath the surface. Our flagship product, MarCast, predicts ocean visibility — so divers, spearfishers, and captains can plan around conditions instead of guessing at them.
See MarCastMarCast is a mobile app for iOS and Android that forecasts underwater visibility. At its core is a proprietary machine-learning model that translates oceanographic and atmospheric conditions into a practical answer to one question: how clear will the water be?
Location-based predictions of water clarity, built for dive and spearfishing trip planning.
A neural network trained on roughly two decades of historical oceanographic data drives every forecast.
MarCast is freemium — core forecasts are free, with premium features for serious watermen.
MarCast's forecasting model is trained on approximately twenty years of ocean and atmospheric observations drawn from leading scientific data programs, combining currents, tides, aerosols, and weather into a single visibility prediction.
Viziato LLC is a marine technology company based in Clearwater, Florida — on the Gulf, where water clarity decides the day. The company was founded to bring modern forecasting science to the diving and boating community, and is the developer and publisher of MarCast.
