PADI eLearning

What PADI eLearning actually is

Every course on this page is the theory half of a PADI course, delivered online. You work through interactive lessons, videos, quizzes and knowledge reviews on whatever device suits you, at whatever pace suits you. There is no classroom to sit in and no fixed dates to book around.

None of them include in-water training. When you finish, you get a digital certificate of completion for the theory portion. The certification card comes from a PADI instructor once you have done the dives, and Oyster Diving runs those sessions, so you can do both halves in one place.

Which course suits you

PADI Open Water eLearning

The starting point if you have never dived. It covers dive equipment, safety procedures, dive planning and the underwater environment. Most people take it for one of two reasons: to get a head start before joining a practical course, or to clear the theory before travelling so the holiday is spent diving.

PADI Advanced Open Water eLearning

For certified divers building on what they learned in Open Water. The knowledge development covers five Adventure Dives: Deep and Navigation are required, and you choose three more from the elective topics. It is open to divers aged 12 and over.

PADI Rescue Diver eLearning

This one shifts your attention from your own diving to everyone else's. It covers preventing and managing diving emergencies, minor and major, including emergency management, diver stress and rescue procedures, taught through real-world scenarios rather than lists. It is also required for anyone working towards PADI Divemaster or Instructor.

PADI ReActivate eLearning

For certified divers who have been out of the water for a while. It reviews the core material — dive planning, buoyancy control, equipment setup and emergency procedures — without sending you back to the beginning. Worth doing before a trip, and it tells a dive operator you have refreshed rather than turning up cold.

Getting from theory to certification

The pattern is the same for all four. Finish the online modules, then book the in-water part. For Open Water that means confined water and open water dives with a PADI instructor. For Advanced Open Water it means the training dives. For Rescue Diver it means the practical rescue exercises, and for ReActivate a skills review session.

Doing it in this order is the whole point. If you arrive at practical training with the theory already behind you, the water time goes on skills instead of knowledge reviews, and you are not trying to absorb new concepts while also learning to breathe underwater.

Studying before a dive trip

A booked dive holiday is the usual reason to take the theory on its own. Working through it in the weeks beforehand means you land ready for the in-water sessions rather than losing days of the trip to a classroom. The same applies to ReActivate: a refresher done at home is a better use of your first morning than working it out at the dive site.
