Which skill can increase your self-rescue abilities?

Having good buoyancy control enhances self-rescue abilities significantly. When divers possess effective buoyancy control, they can manage their position in the water effortlessly, which allows them to remain calm and conserve energy. This skill helps a diver maintain a safe and comfortable position underwater, facilitating essential actions such as signaling for help or preparing to ascend safely to the surface.

Underwater navigation is also beneficial, as it allows divers to understand their orientation and be aware of their surroundings. This skill can help divers find their way back to a safe exit point if they encounter difficulties or disorientation underwater.

Airway control is vital, especially in emergency situations when a diver may need to ensure they can breathe properly while managing a stressful situation. Knowing how to manage airway control can contribute to a diver's ability to self-rescue by keeping their calm and ensuring they have access to air when needed.

Each of these skills plays an important role in a diver’s safety and ability to self-rescue in different scenarios, making it clear that a combination of these skills contributes to enhanced self-rescue abilities. Thus, acknowledging that all the options listed contribute to self-rescue reinforces their importance in diver training and preparedness.
