Your PADI certification never expires; but if you haven't dived in a while, it's best to be prepared. Dive shops also appreciate seeing a recent reactivation date on your certification card.
ReActivate is the engaging and effective way to refresh your diving skills. In the first phase, you'll quickly cover topics you're familiar with, then dive deeper into topics you may have missed. Schedule an optional in-water practice with a dive professional and receive a new card recognizing your new "Reactivated" date.
