Advanced Buoyancy Control

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.

Skills you will own after this course!

Streamlined Trim

Precise Weighting

You’ll learn to use exactly the weight you need and place it correctly, unlocking easy descents, stable stops, and effortless neutral buoyancy.

Efficient Propulsion

You’ll improve your finning so every kick counts: more forward motion, less vertical bounce. Efficient, quiet movement that conserves energy and gas.

Smart Configuration

You’ll explore BCD options: jacket, back‑inflate, wing, plus drysuits and hose routing to streamline your profile and boost comfort, control, and stability.
