ReActivate is a new PADI app that allows divers to get a full scuba knowledge review anywhere they go with their mobile device. Not only is it the most convenient option, but you can take it with you on your trips and refresh your memory on the go. If you plan to take scuba lessons on vacation, dive centres and resorts will appreciate seeing a recent ReActivate date on your certification card because it means you’re ready to dive in. Divers who complete both the knowledge review and in-water skills workshop receive a replacement certification card with a “ReActivated thru” date on it.
