    • Advanced Adventure Diver

      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. The remaining specialty dives are up to you!

      The SDI Advanced Adventure course is Equivalent to PADI’s Advanced Open Water Scuba Diver Certification. 

    • Advanced Diver

      The SDI Advanced Scuba Diver Development Program was created to make truly “Advanced Divers.” During the course your Instructor will take you through four complete SDI, TDI, or ERDI specialty courses (for example; Deep, Navigation, Photo, Video, Intro to Tech, Tender, etc.) covering all the skills and subjects, so that by the end you will feel comfortable to conduct dives of a similar nature.

      There is no equivalent course PADI offers that matches SDI’s Advanced Diver certification. SDI labels the accumulation of 4 Complete specialties as its Advanced Diver certification, because upon completion full comprehension of each specialty is obtained. The PADI Advanced Diver (equivalent to SDI Advanced Adventure Diver) partially covers 5 specialties. To gain full comprehension of each specialty, the student would next be required to train in each specialty diving class separately. 

      By earning the SDI Advanced Scuba Diver certification you will have increased abilities and comfort in the water and be ready for the next step, SDI Rescue Diver.

    • Rescue Diver

      The SDI Rescue Diver Course is designed to develop the knowledge and necessary skills to effectively perform diver rescues, as well as, assist and administer the necessary first aid in the event of an emergency.

After the SDI Rescue Diver Course you can enroll in the SDI Master Scuba Diver Development Program or start in the professional ranks and sign up for the SDI Divemaster Course.

  • SDI Specialty Courses

    These courses are for already certified divers, independent of their skill level, who wish to expand their knowledge of a specific area of interest.

    • Advanced Buoyancy Control

      Introducing a diver to the benefits of controlling his buoyancy usually has a great positive effect, an effect that will enhance the diver’s sense of enjoyment and feeling of accomplishment. This specialty is designed to increase the open water diver’s understanding of the factors that influence buoyancy, and to train the diver how to use the means available to him as methods for controlling his buoyancy. The added benefits to the marine and freshwater environments, cannot be overstated; as well as a diver that has better control of himself in conjunction with his environment.

    • Boat

      Boat Diving occurs every day around the world; whether it is in the Long Island Sound, a lake or in the Caribbean, South Pacific or Read Sea, divers can explore the underwater world located off-shore.

    • Night/Limited Visibility

      Many divers find that night diving is their favorite type of diving. As with all specialty diving applications, procedures are different than those associated with open water diving. The purpose of this course is to acquaint the open water diver with the procedures, techniques, and potential hazards associated with diving at night, or in limited visibility. Becoming familiar with the use of dive lights, and night diving techniques such as navigation, buddy system procedures, communications, buoyancy control, and interacting with nocturnal aquatic life, the diver can safely enjoy night diving.

    • Research

      The purpose of this specialty course is to acquaint the open water diver with the fascinating topic of research diving. After the completion of this course, a diver will be better able to discover, explore, and appreciate the underwater environment by using research techniques and better preserve and protect the underwater environment.

    • Sidemount

      As equipment changes make diving easier, they are incorporated into diving. One of those changes has been sidemount cylinders. Sidemount cylinder use has exploded on the scuba diving scene. This course is designed to teach certified divers how to safely utilize side-mounted primary cylinders as an alternative to the traditional back-mounted configuration. The course is strictly non-decompression with a maximum depth limit of 40 metres/130 feet, or within the limit of the student’s current certification, whichever is shallower

    • Solo

      At one point or another, many divers have found themselves alone during a dive, whether it was intentional or not. SDI’s Solo Diving is the practice of self-reliant scuba diving without a “dive buddy”. Solo diving, once considered technical diving and discouraged by most certification agencies, is now seen by many experienced divers and some certification agencies as an acceptable practice for those divers suitably trained and experienced. Rather than relying on the traditional buddy diving safety system, solo divers should be skilled in self-sufficiency and willing to take responsibility for their own safety while diving. Being one of SDI’s most popular courses, the Solo Diver course stresses proper dive planning, personal limitations, and accident prevention, as well as the benefits, hazards, and proper procedures for diving solo. You will also learn the additional equipment that is required for solo diving including its proper usage and assembly. This is the perfect course for underwater photography and underwater video divers as well as those diving with their children or buddies that may not very experienced in scuba diving.

    • U/W Hunter & Collector

      The purpose of this specialty course is to actively allow the student to engage in the collection of certain marine objects and to demonstrate and explain the necessary rules of underwater hunting. Prudent and conservative techniques of both aspects must be exercised. The SDI Hunter/Collector Diver Course covers the “how-to’s” of hunting and collection of marine life.

    • U/W Navigation

      Divers are intensely fascinated by navigation… It allows them to make their way back to a special spot discovered on an earlier dive. They use the tricks and techniques of navigation to find an ideal exit point at the end of a dive without the need for an uncomfortable surface swim. Your SDI Underwater Navigation Specialty course will help you overcome the obstacles inherent to finding your way underwater. You will learn how easy and simple navigation can be and how it will help you both above and below the surface. During this course, you will review natural aids such as sand ripples or reef formations, which can accurately predict your route. Tools such as mechanical or digital compasses are a surprising challenge to the novice but we will help you unravel the challenge and teach the practical skills and techniques you’ll need to use them effectively.

      This course is designed to give students a greater understanding and experience on how to properly navigate underwater using both natural and compass navigation.
