After completing the basic course, you have already necessary skills for safe diving at depths of down to 18 meters. However, wrecks, Atlantis cities, gold of the conquistadors and other secrets of the World Ocean tend to be deeper.
The course of deep diving will allow you to reach the maximum nonprofessional diving depth of 40 meters.
There are no white spots on the map of the Ocean, there are places only where you have not been.
