If you have not been fortunate enough to have been diving within the last 12 months and you have less than 50 dives logged, then we request you to take a Scuba Tune-Up, prior to embarking on one of our Liveaboard or Daytrips, for your own enjoyment and safety. It is a long way to go to the Similan Islands only to discover that you do not remember exactly how it all works, become anxious, use air excessively and ultimately have short dives.
