Master Your Buoyancy. Transform Your Diving. Without buoyancy, there’s no good diving. SDI Advanced Buoyancy Diver isn’t just another card; it’s your pass to becoming a truly capable diver. You’ll gain major safety, especially on ascent and at your safety stop. Improve your body position, reduce effort and gas consumption, and treat the marine environment with the respect it deserves. OWN Every Ascent and Stop Stop exactly where you want, even at your safety stop. Prevent uncontrolled ascents and keep visibility clear by avoiding kicked-up silt. With precise buoyancy, you control the dive, not the other way. Perfect Your Horizontal TRIM A truly horizontal profile makes you hydrodynamic. Less drag means less effort and lower gas consumption, so you swim farther, feel better, and enjoy more bottom time on every dive. Hover CLEAN, Protect Reefs Solid buoyancy lets you hover above the reef, avoid fin strikes, and leave no trace. No sediment clouds, no accidental contact, just respectful, conservation-minded dives that protect the places you love. 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 prerequisites: 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 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. SDI Advanced Buoyancy Diver minimum requirements: Complete all open water requirements efficiently Demonstrate sound buoyancy techniques
