Description
A great next step after Open Water that gives you a real taste of five different SDI specialties, including the foundational Deep Diver and Underwater Navigation experiences. Rather than committing to a full specialty up front, you’ll sample each one through a single adventure dive, expanding your skills and discovering which types of diving you enjoy most. It’s an efficient, fun way to become a more capable, well-rounded diver while gaining supervised experience across a variety of environments and conditions. Best of all, each specialty dive you complete can later count toward the full certification in that specialty, so you get a head start on your continuing education.
If you’ve taken your Open Water Scuba Diver course and are now ready to expand your knowledge but would like to see what is out there first, then the SDI Advanced Adventure Diver course is for you! The SDI Advanced Adventure course will give you an overview of five different SDI specialties. Two of the required specialties are the Deep Diver and Navigation Diver specialties which are the foundation of continuing diver education.
Dives included: 5 open water dives (including one deeper dive to 18–30 m / 60–100 ft and one navigation dive).
