SDI Advanced Buoyancy Diver


Introducing a diver to the benefits of controlling there 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 them as methods for controlling their buoyancy. The added benefits to the marine and freshwater environments, cannot be overstated; as well as a diver that has better control of themselves in conjunction with his environment.


Who this course is for:

  • The certified diver looking to improve and/or fine-tune their buoyancy to prevent damage to the underwater world.

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.


Course prerequisites & forms:

  • SDI Open Water Scuba Diver, SDI Junior Open Water Diver, or equivalent
  • Minimum age 18, 10 with parental consent

What you can expect to learn:

 The SDI Advanced Buoyancy Diver course takes an in-depth look at all of the following and more:

  • Why do we care about buoyancy?
    • Don’t touch the aquatic life, save the environment
    • Less fatigue, less effort required, more fun
    • Reduced air consumption = more bottom time
    • Able to control buoyancy = better pictures or video
  • When must a buoyancy check be performed?
    • When equipment is changed
    • When diving environment is changed
    • Have not been diving for a while
    • During every dive
  • Buoyancy factors
    • Additional equipment; photo, video, extra cylinder, extra equipment, dive lights, etc
    • Cylinder weight changes during a dive as air is consumed from the cylinder, dependent on cylinder size
    • Using lungs vs. BCD.
    • Using BCD vs. dry suit
    • Staying physically fit
    • Breathing patterns and technique
    • Compression of suit due to water pressure
    • Weights – position and distribution and what impact that may have
    • Streamlining equipment
    • Streamlining body (body positions)
    • Efficient kicking style
    • Practicing your skills
    • Weighting
    • Swimsuit
    • 3mm and 5mm wet suit
    • Cold-water suit with hood
    • Dry suit
    • How to perform a standard buoyancy check; with an almost empty cylinder

Some of the required skills you will have to demonstrate include:

  • Assembling of dive equipment
  • Pre-dive check
  • Perform a pre-dive buoyancy check with almost empty cylinder
  • Adjust weight to achieve correct buoyancy
  • Change cylinder and use a full cylinder
  • Do a pre-dive buoyancy check with full cylinder
  • Controlled descent
  • Hovering exercises
    • Fine-tune with breath control
    • Fine-tune with BCD or dry suit
    • Close to bottom exercises, no touch
  • Swimming exercises
  • Ascent that includes a safety stop hovering; simulate safety stop if in pool
  • Log dive, noting the amount of weight used
  • Change to a full cylinder
  • Do a pre-dive buoyancy check with the full cylinder
  • Controlled descent
  • Ascent that includes a safety stop hovering; simulate safety stop if in pool
  • Log dive, noting the amount of weight used

What’s in it for you?


Upon successful completion of this course, graduates may engage in diving activities without direct supervision of the SDI Instructor* so long as the following limits are adhered to:

  • 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 advanced buoyancy diving activities with a parent, guardian, or dive professional.

The SDI Advanced Buoyancy Diver certification counts towards a single specialty rating to achieve the SDI Advanced Diver Development program.
