Your SDI Instructor will also teach you how to manage divers, work the dive deck of a boat, and conducting safe and enjoyable dives. Other things you can expect to learn is diving Physics and Physiology, and being a professional SDI Divemaster. Your skills will be refined to demonstration quality and your knowledge increased to that of a professional. After you have completed the SDI Divemaster course you can move onto the SDI Assistant Instructor Course where you will learn more about academic presentations and have the ability to teach certain SDI specialties.
