The search for perfect buoyancy is in every diver’s mind. Whether you’re new to the sport, or a certified professional, we all strive to continually demonstrate this skill. But is this ‘skill’ really within the reach of newly certified divers…? In my opinion: absolutely!
Buoyancy within regular SCUBA diving comes down to five key factors:
- Breath control,
- Proper weighting,
- Balanced equipment,
- Correct BCD usage, and
- Anticipation and action.
And for this particular post, we will focus directly on breathing technique.
Within the PADI system, it says: “Underwater I should breathe slowly, deeply, continuously and never hold my breath.” In my opinion, the ‘slowly’ and ‘deeply’ create problems, as your buoyancy is greatly affected by how much air is in your lungs, and the duration to which it is ‘held’ there.
So instead, I have found the following ‘thirds’ model to be far more effective. Imagine your lungs being divided into thirds (it would look something like this):
