SDI Underwater 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.


Who this course is for:

  • The certified diver looking for a higher sense of direction and orientation while scuba diving

Course Duration:

Courses should not be treated as a race or something that can be skipped through quickly. Please remember training does not guarantee certification, we need to ensure you fully understand the training and will be a safe diver on certification. We follow a loved one clause that when certified we would be happy you could safely dive with one of our loved ones.

  • The e-learning and academic portion of this course should be completed before starting in water training and exercises. The duration of this piece is dependant on your availability. During this time our instructors are on hand to assist with questions or any element you may struggle with.
  • For many courses the swimming pool or confined water sessions give us time to practice and carry out skills in a controlled environment. We do not fix specific number of pool sessions as it is dependant on your comfort level with skills before moving to open water.
  • The open water element is again determined more by time in water rather than number of dives. We prefer longer dives building experience rather than quick short 20 minute 'dips'.
We will strive to meet your timelines and requirements where possible and will always be dependant on student availability to attend sessions.

  • SDI Open Water Scuba Diver, SDI Junior Open Water Diver, or equivalent

          • The diving activities approximate those of training
          • The areas of activities approximate those of training
          • Environmental conditions approximate those of training
          *Note: Junior divers (ages 10-14) must participate in underwater navigation diving activities with a parent, guardian, or dive professional.
