Suba Review  Haven't dived for a while? Then a PADI Scuba Review is just the ticket. The first way to refresh your skills is to book a pool training session with a Dimaniyat Instructor to re-master all the skills you learnt on your PADI Open Water Diver Course. Alternatively you can book a Discover Local Diving Tour with a Dimaniyat Instructor and refresh on the skills as you are guided around one of the many beautiful dive sites of Oman. We recommend a refresher if you haven't dived in at least a year or for those who simply wish to keep the skills and knowledge fresh and up-to-date.
