Why Peak Performance Buoyancy? If you want to fine-tune your buoyancy and soar over reefs, extend bottom time by reducing air consumption and prolong the life of your dive equipment, the Peak Performance Buoyancy Speciality course is for you. What do I need to start? PADI Open Water Diver or Junior Open Water Diver certification (or qualifying certification from another organisation) Minimum age: 10 years old. During your Peak Performance Buoyancy Speciality course, you'll use PADI's Basic Weighting Guidelines to determine the correct amount of weight. Then you'll practice the fundamentals of peak performance buoyancy during two open water dives, including the buoyancy check, fine- tuning buoyancy underwater, weight positioning for trim, streamlining and visualisation.
