Buoyancy control is very important in diving. Knowing how to do this can save a lot of coral formations from being destroyed. This can be a little bit tricky because our lungs tend to expand as we go up. A little push of the button can take us higher than we expected. And, when we push the button for descending, we may end up crashing on the corals.

Before entering the water, you should do some buoyancy tests at the surface. With your BC completely deflated, try to hold an upright and motionless position. If the weights on your weight belt are properly distributed, you will float in the water at eye level. You can also try inhaling and exhaling in that position. You will notice that you'll descend every time you exhale and ascend every time you inhale. Once you've achieved the proper breathing pattern, you don't need to depend on ascending and descending with your BC too much.
