What does DSD Leader mean you can do? DSD Leader does not mean Instructor but it does require some Instructor adjacent skills that you will find useful if you’re planning to do qualify further in future. What a DSD Leader can do is lead people on Discover Scuba Dives in confined water, meaning: a swimming pool or confined water like conditions, which is an open water site that offers swimming-pool-like conditions with respect to clarity, calmness, and depth (6m). This course is for PADI divemasters looking to take the first step towards helping people discover a new passion. There is nothing better than seeing someone have an awesome time and helping them discover the same love for scuba that you have.
