Planning to do an Open Water dive course? Feel confident before you buy a course or use as a refresh.

NOW COMPLETELY FREE.

Watch your instructor demonstrate every practical diving skill — before you even enter the water. All 21 Open Water skill circuits are included as video demonstrations, with subtitles in your language, so you know exactly what to expect and how to perform each skill correctly.

Before the dives, every course (PADI, SSI, etc.) includes theory—for example: pressure, buoyancy, equipment, dive planning, and safety rules. Open Water Dive Theory Beginner includes all the required theory. This allows you to learn everything before you pay for an official course. Lessons are short and interactive, with quizzes to check your understanding.

All lessons can also be read aloud by the app, so you can listen instead of reading. You get access to all available languages, allowing you to switch between them at any time. This is a big advantage for non-native speakers of English to get familiar with English diving terms, as most courses worldwide are in English. It is also very useful for dive instructors and divers who want to communicate with people from other countries.

Also ideal to refresh your dive theory knowledge!
