I did my PADI Open Water Diver Certificate with Rohanna and his guys and I can fully recommend the Sea Horse Crew! We were no more than 2 students at a time, the explanations were good, and I always felt very safe. I had only a couple of days in UnaWatuna and I was very nervous that I could get it done in this short time. But Rohanna managed to pack it all in and still make it all go nice and smooth and safe while being very relaxed and flexible. So, just relax and trust the guys and will all work out!
