12/ Buoyancy control
17/03/12 14:20
Neutral Buoyancy is indicated by remaining still (hovering)
Good buoyancy control makes you a better and safer diver, one who
is easier to dive with, and one who doesn’t harm the environment. Work on it, ask for advice, and if you are having trouble, consider taking the peak performance buoyancy course.
In General:
• As you descend:
- After letting air out of the BC, exhaling and relaxing (don’t kick )
- Keep the volume of air in your BC ‘the same’:
(add air, as the pressure is contracting the existing air in the BC )
-Stop before you hit the bottom, avoid coral and don’t silt up the site
•After you establish neutral buoyancy, breath normally, but:
-use breath control to make small adjustments at a given depth
-don’t hold your breath, ever.
-breath in the part of the lungs that serves your needs at the time
•Large adjustments in depth may require BC inflating (puffs) & purging
•Small adjustments in depth: use your lungs, but don’t hold your breath
•As you ascend: - Keep the volume of air in your BC the same:
(let air out, as the falling pressure allows air to expand in the BC )
