Patrick had got his Open water diver certificate 2 years ago , and didn't dive since then. It was difficult for him to adjust to the water condition and equalize at the first dive, but he kept on trying. He managed to control his buoyancy and equalize just fine the second dive. The visibility was good and water temperature was up to 27 celcius degrees. A little bit of currents. I'm glad he enjoyed diving in Jeju. Hope to see him again in March :)
