6 Tips for Better Bouyancy Control
Send me emails
-
Minimize your weighting. Extra air in your
BC, to support extra lead on your belt, will
change volume and buoyancy with depth, causing
you to yo-yo and preventing you from maintaining
neutral buoyancy.
-
Check it at the safety stop. It's at the end
of your dive, not the beginning, that you should
be weighted for neutral buoyancy at 5m. That
means you'll be about 2kg heavy at the beginning
of the dive. (That's the weight of the air you
use.)
-
Suspend a weight bag. Hang a mesh bag with
some 1kg weights from the boat at about 5m.
Start the dive with 1kg or so of your weight in
a BC pocket. At the safety stop, next to the
weight bag, you can transfer weights between
pocket and bag to find your perfect weighting.
-
Relax. To find neutral buoyancy, go limp.
Any sculling with hands or feet will create
upward thrust.
-
Add and subtract air in small squirts. You
must wait a minute for adjustments to take
effect before adding or subtracting more. The
effect is not instantaneous.
Use your lungs, not your BC.
Make slight temporary changes to your buoyancy by
holding more or less air in your lungs. That way you
don't disturb the correct inflation of your BC. |
