Haven’t been diving lately and want a quick scuba refresher? Perfect to do over the Winter months, the ReActivate™ program is the ideal way to update your dive skills and knowledge from the PADI Open Water Diver Course before jumping back into the water.

Whether you want a few reminders or need to go over the basics, ReActivate is personalised for you: You conveniently review scuba concepts on your tablet / mobile device or computer, then go diving with a PADI Professional.

It’s quick and easy, and a good way to prepare for your next PADI course or get ready for a holiday.


  • Our staff are here to help you improve your diving, not just tick a box. We are not a certification ‘factory’ we are here to develop safer, more confident divers.
  • We keep our class sizes small so that you feel more comfortable and get the most out of your session
  • Everything is explained in simple steps, guided by our experienced instructing team. There are no ‘stupid questions’
  • We understand that you haven’t dived for a while and refreshing your skills may take time and patience!

Divers who complete both the knowledge and in-water skill refresher receive a replacement digital certification card with a ReActivated date on it.
