Do you know that our Earth area is covered by more than 70% water? Our oceans and water systems that include lakes and rivers that support living organisms is still an unexplored territory 95% visible by human eyes. You may have gone swimming in the sea or snorkeling along a reef ... but now, it's time to take it one step further. See the underwater world as it should look underwater. Become part of an ecosystem that supports so much of our lives and take it to the limit, interacting with colorful bands of underwater fish or diving alongside a flock of dolphins who come to look at you closely. Dive with sharks, dive in caves or dive in sunken ships.


No matter what direction you might want to take in your new lifestyle; It all starts here.

SDI's One Star Diving Course is an entry-level certification course designed to give you the necessary skills to safely manage open water dives. Some of the skills you can learn include buoyancy, proper weighting, marine conservation, scuba diving equipment, proper dive planning, and maintenance. It covers all basic knowledge about equipment, physiology and marine environment. A one star diving course is the key to start exploring dive destinations around the world or just in your backyard.


The SDI One-Star Diving Course lasts 5 days, where you will be trained as a diver and can dive to a depth of 18 meters.

The following is a one-star diving course content.


Open Water Scuba Diver

This initial certification is designed to provide the apprentices with the necessary skills to perform dives in open water in conditions similar to those they practiced without the direct supervision of a counselor. After completing this course, the authorized will be able to dive in open water in conditions similar to those they practiced. Sign up for SDI's 2nd Star Diving Course.
