Diving could be a dangerous activity if something goes wrong. If you keep diving, you might face some dangerous situations at some stage.

Learning how to handle those situations will give you lots of confidence, and let you enjoy your diving life more.

We cannot make risk zero but can minimize it. And in case something does happen, we need to act to keep it to the minimum. That's what you learn in this course.

Dives required : 2

Refresher Course

If you have not dove for a long time and are not sure about diving, it might be a good idea to quick refresh your skill and knowledge so that you will be confident in diving again.

Refresher course is NOT a certification course, so what we do depends on what you wanna do.
