The PADI Open Water Course is the world’s most popular diver certification and is intended for people who have never dived before and who want to become qualified.

The Open Water Course combines practical in water training with some supporting theory so that you can confidently and safely explore the amazing underwater world.

Once certified you will be able to dive to 18m with a buddy.

  • We keep our class sizes small so you feel more comfortable and you enjoy your session more.
  • Everything is explained in simple steps, guided by our experienced instructing team.
  • We understand that everyone is not necessarily a natural on day 1!

Course Description

Part 1: Knowledge Development

This develops your familiarity with basic principles and safety concepts of diving.

You complete the knowledge development in your own time, using your selected version (Paper or Digital) and by completing the knowledge reviews.

You briefly review what you studied in each section with your instructor and take a short quiz to be sure you’re confident with the information.

You also take a short exam that makes sure you are happy with all the key concepts.

Part 2: Confined Water (Pool)

In the pool you will experience your first breaths underwater and learn the skills required to dive in the open water, and to dive safely.

Part 3: Open Water Dives

Four open water dives are required for certification with two dives conducted over 2 days.

You now get the chance to put to practice what you learnt in the pool and fully experience the adventure of diving in the open water!

This could be with Aquanaut at a local UK dive site or you can join one of the Aquanaut holidays such as Portugal or Malta (flexible dates, minimum 4 people) .
