Scuba Diving and Buoyancy Control Device

Hi Leslie O'Neill here with Scuba-Explorers. Another common question over the past 27 yrs of teaching is:

What is one of the most difficult things to do when you first learn to scuba dive?

Buoyancy Control is one of the most important skills to learn. It takes time and experience to master.

While on the surface we want our BC's to be fully inflated at all times until we are ready to descend.

Also the second our head touches the surface - we will power inflate our BC's and not a moment sooner.

As we descend deeper in the water we become more negatively buoyant because of the increasing pressure on all airspaces. Therefore we puff
a slight bit of air from our low pressure power inflator into our BC to neutralize our descent- by doing so will reduce the amount of effort equired to swim or to keep from sinking and becoming more negatively buoyant.

New divers tend to over compensate- ....sending them back up to the surface which will require them to begin the equalization process
all over again as they work their way back down to depth.

This also requires the use of more air than necessary. Try making small corrections while inflating or deflating until you gain a comfort level.

You will master this with more experience; I promise!
