Open Water Diver
The Open Water Diver course is your first step in the world of scuba diving.
It is a simple and safe coure where you will learn the basic knowledge of scuba diving, using ISDA book, videos, quizzes and the explanations of your instructor.
You will learn how the pressure of water affects our body, how to communicate with your dive buddy and how to use the equipment before and during the dive.
The course
The practical exercises will gradually bring you to become familiar with the equipment and being underwater; sooner than you think you will fly in the water, at ease in the new "planet" just discovered.
With the Open Water Diver certification you can dive all over the world up to a maximum depth of 18 meters.

If you want to complete your basic training and have the opportunity to explore seabed and coral reefs up to 30 meters, try the thrill of diving at night or explore fascinating wrecks, proceed with the Advanced Open Water Diver course.
