One dive is not enough! A 2-dive diving experience for those who want to dive a lot. It is a course to dive into the sea twice with a break by changing the point or course. Most people are full of tension when diving for the first time! Most people end up not being able to see the fish and the surrounding underwater landscape with plenty of time. I'm sure that in the second dive after getting used to it, you will be able to get to know what you did not notice in the first dive, and you will be deeply moved. * I really want to see sea turtles! Please consider participating in the "Special 1 Dive Course". By diving a single dive for a longer period of time, you can go further offshore and the sea turtle encounter rate will increase dramatically.
