After finished open water diver course. I continue to learn Advanced open water diver course. Beginning at wreck ship. I’m very excited when going to wreck ship because it’s my first time and the biggest wreck ship in Thailand !! There is a leader for diving trip. Before diving, He advise us what we should do. Underwater he takes care and hand signals to us all times. And we have buddy to help each other. During diving close to the wreck ship, There are a large group of fish (both small and big) and a group of barracudas. It’s very beautiful scene but I can’t take photo like that I see. It’s a lucky day, the visibility is very good. It make us see underwater clearly. We dive around the wreck and look marine lives. Before get back to surface, We make safety stop 3 minutes in 5 depth. Another dive, It’s Navigator dive and We see 3 lion fish fortunately. The lion fish is rare to see at Koh Chang normally. I can bring my knowledge from photograph dive to use in this trip after I learnt just one day. It’s very useful to me
