Adding air to the BCD and dry suit should be practiced in which environment initially?

Practicing adding air to both the buoyancy control device (BCD) and dry suit in a confined water environment is crucial for several reasons. Confined water provides a controlled setting where divers can focus on mastering the techniques without the added complexities and potential hazards of open water scenarios.

In a confined water environment, divers can familiarize themselves with the buoyancy characteristics of both the BCD and dry suit, which allows them to understand how adding air affects their buoyancy and overall underwater control. This practice helps divers develop muscle memory and confidence in adjusting their buoyancy, which is essential for safe and effective diving.

The absence of currents, waves, and varying visibility in confined water allows divers to concentrate solely on their equipment and buoyancy management skills. Once they have practiced and become proficient in a controlled setting, they can transition to open water conditions with greater confidence and safety.
