Advanced Buoyancy Diver (SDI)

This course is designed for certified divers who want refined control rather than constant adjustment in the water. You’ll focus on buoyancy, trim, weighting, and propulsion so dives feel calmer, more efficient, and more deliberate.

Instruction is private or semi-private (1–2 students), allowing detailed feedback and repetition until precise control becomes second nature. Successful completion earns a specialty certification centered on advanced buoyancy and body-position skills.

• Proper weighting techniques for different exposure protection and environments
• Horizontal trim and body positioning to reduce drag
• Fine buoyancy control using breath control rather than frequent BCD adjustments
• Hovering techniques at depth and during safety stops
• Efficient propulsion methods to minimize effort and silting
• Buoyancy control during ascents, descents, and task loading
• Equipment configuration considerations that affect balance and control

• Reduces the risk of uncontrolled ascents or descents
• Improves gas efficiency through streamlined movement
• Protects reefs and bottoms by preventing accidental contact
• Builds confidence in varied conditions and environments
• Makes every dive smoother, calmer, and more enjoyable

1. Knowledge Development: Self-paced learning covering buoyancy theory, weighting, trim, and propulsion concepts. Most students complete this in short sessions.
2. Instructor Briefing & Setup: Review of equipment configuration, weighting checks, and buoyancy goals based on your exposure protection and environment.
3. Open-Water Training Dives: Coached dives focused on hovering, trim adjustments, propulsion practice, and controlled ascents/descents. Typically completed in one day, depending on conditions and pacing.

Required personal scuba gear:

• Mask, snorkel, fins
• BCD, regulator, computer
• Exposure protection appropriate to conditions (wetsuit or skins as needed)

If you’re unsure about weighting, fit, or configuration, we’ll help you fine-tune your setup before and during training.

• Included:
• Private (1 student) or Private Group (2 students) instruction
• SDI digital learning materials (eLearning or equivalent materials as available)
• Instructor-led briefings, in-water coaching, and debriefing
• Certification processing upon successful completion

• Not included (varies):
• Personal scuba gear (you supply your own or rent; rental availability varies by location)
• Location or entry fees
• Charter boat fees (if applicable)
• Travel, lodging, meals, and optional purchases

We confirm third-party costs during the consult before you commit.

• Minimum age: 18
• Prerequisites: Open Water Diver certification (or equivalent)
• Water skills expectations: Comfortable basic buoyancy control and stable ascents/descents
• Medical: Completion of a medical questionnaire is required; physician sign-off is needed if indicated prior to in-water training

• Is this course useful for experienced divers? Yes. Even experienced divers often discover inefficiencies that can be refined.
• Is training private? Yes. Instruction is private or semi-private for focused feedback.
• How long does the course take? Most students complete it in one day after academics, depending on conditions.
• Will this help my air consumption? Improved buoyancy and trim often lead to better gas efficiency.
• Where does training take place? At sites chosen for calm conditions and effective skill development.
• What if I need more practice? Additional coaching sessions can be added; certification is based on demonstrated skill.

Your phone consult helps us understand your experience, equipment, and typical dive conditions. We’ll outline a focused training plan and confirm logistics before scheduling.

This ensures your buoyancy training is practical, effective, and matched to how you actually dive.
