Overview
The SDI Advanced Buoyancy Diver course develops the knowledge and practical skills required to achieve precise buoyancy control and improved underwater positioning.
Excellent buoyancy is one of the most important skills a diver can develop. Improved buoyancy control enhances safety, reduces gas consumption, improves comfort, protects the underwater environment, and increases overall diving enjoyment.
Training focuses on:
- weighting procedures,
- trim,
- buoyancy control,
- breathing techniques,
- propulsion efficiency,
- and underwater awareness.
At N9BO℠, Advanced Buoyancy Diver training helps divers refine the fundamental skills that support every aspect of recreational, professional, and technical diving.
