What is one method of increasing buoyancy while diving?

Inflating your Buoyancy Control Device (BCD) is indeed a key method to increase buoyancy while diving. The BCD is designed to allow divers to control their buoyancy, making it possible to ascend, descend, or maintain neutral buoyancy at a desired depth. When you inflate your BCD, air fills the bladder, decreasing your overall density compared to the surrounding water, which helps you float more easily.

This method is crucial for divers when they need to adjust their buoyancy for various situations, such as ascending safely to the surface or hovering at a specific depth without expending excessive energy. Using the BCD for buoyancy control is a fundamental skill and safety practice in diving, enabling divers to manage their buoyancy effectively throughout the dive.
