SDI Advanced Buoyancy Control

Why choose this course?

This course is ideal for certified divers who want to fine-tune their buoyancy and take their diving skills to the next level while preserving the beauty of the underwater world.

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
• Hovering exercises
  • Fine-tune with breath control
  • Fine-tune with BCD or dry suit
  • Close to bottom exercises, no touch
• 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.

Extra training

If the course cannot be completed within the dives planned and further training is deemed necessary we offer additional training. The costs for this are €150,- per extra day of training.
