Zero visibility - Basket star - Astrospartus mediterraneus
When we dive at depths greater than 40 meters and far from the coast, about 7.5 nautical miles, it is difficult to make predictions about sea conditions such as currents, presence of fish and marine organisms but above all visibility on the bottom. If weather forecasts are now reliable and safe over 24/48 hours, it is practically impossible to predict what will be found on the bottom once immersed.
