Big Blue Conservation - Koh Tao - Thailand

Specialty Courses

At Big Blue we offer a wide range of both PADI and SSI speciality courses aimed specifically at those who are interested in marine conservation. Some of the courses are specifically conservation based but some are aimed at improving your diving skills in order to minimise accidental damage underwater or offer the opportunity to learn skills that may be used in conducting research.

BSAC Marine Conservation

BSAC Marine Conservation Speciality Diving Course is the first of BSAC's ecological minded courses. As divers, we are in the prime position to help our reefs remain the paradise they are today. To help educate and alert divers of the problems affecting the reefs, Big Blue Conservation has helped construct a new speciality supported by BSAC on Marine conservation. As an observational sport, knowing a little more about what you see underwater and improving your buoyancy skills and air consumtion will help influence low-impact diving.

SSI Navigation

To be an independent diver, it's vital to be able to navigate underwater. Just like on land, underwater navigation is a combination of using natural landmarks and compass work. The SSI Navigation course will teach you how to navigate with a compass and how to apply natural navigation skills. You will also learn how to estimate distances, navigate different search patterns, find your way to different marking points and to get back to the exit point at any time.

SSI Perfect Buoyancy

Weak buoyancy skills cause a huge amount of accidental damage to marine life. This course is ideal for any diver who wants to improve diving skills and at the same time wants to reduce the risk of them causing accidental damage to the reef. Improving your buoyancy skills means that you can get a closer look at the marine life without worrying about bumping into things. This course also helps improve your underwater photography skills by teaching you how move slower or even stop in the water. Having good buoyancy control also improves your air consumption.
