What You Learn

The PADI Open Water Diver course consists of three main phases:

  • Knowledge Development (online, home study or in a classroom ) to understand basic principles of scuba diving (5 modules)
  • Confined Water Dives to learn basic scuba skills (5 pool training dives).
  • Open Water Dives to review your skills and explore (4 open water dives).


To enroll in the PADI Open Diver course or Junior Open Water Diver course, you must be:

  • 12 years or older (PADI eLearning requires a minimum age of 13 years due to international internet laws).
  • You need to be able to swim and be happy in the water to safely enjoy learning to dive.  

The course structure explained

Your first breath underwater is something you'll never forget and you will progress through the skills from basic to more complex. The latest PADI Open Water course is split into three parts –

During Part 1 you'll get to learn about all the important principles of safe and enjoyable scubadiving, this theory section is delivered through a brilliantly designed eLearning package which you complete online.

In Part 2, you complete at least five pool training dives in the National Aquatic Centre Blanchardstown where you master all of the key skills under the helpful eye of a PADI Instructor.  Once you have successfully completed all sections of Parts 1 and 2, you are ready to move on to the final part.  

Part 3 requires that you complete four open water dives in the sea where you get to demonstrate your new skills in the real environment. You can choose different locations depending on your needs, Sandycove Beach just south of Dublin is really convenient but you might prefer the clearer waters off Connemara  or the warmer waters of a tropical location. There is great flexibility in how Part 3 is delivered so we can help you decide what’s best for you.  

The Scuba Gear You Use

In the PADI Open Water Diver course, you learn to use basic scuba gear and standard accessories. Oceandivers supply all the scuba equipment required by their students for the Open Water course, the use of our school gear is included in your course fee. All our scuba gear is regularly updated and well maintained but you might prefer to purchase your own Mask and Snorkel, and we offer a special price on a number of packages. 

The Learning Materials You Need

All the training materials you will need are included in the course fee - eLearning personal access codes - Dive Logbook and Student Record file.

PADI's Open Water Diver materials cover what you need to know about basic scuba diving skills, terminology and safety procedures. For each concept you'll read a description and watch a video demonstration followed by completing the online Quizzes and Knowledge Reviews. Then you'll head to the pool to practice these skills with your instructor. 

Course Timetable

We typically run our Open Water courses over six weeks of evening classes meeting every Tuesday at 7.00pm in the National Aquatic Centre, Blanchardstown. The first part of the evening is classroom based followed by gear selection and assembly on the pool deck before an hour long in-water session of skills and fun in the pool. Finishing time each Tuesday is about 10.15pm.
