How is the term ‘personal floatation device’ (PFD) related to diving?

The term ‘personal flotation device’ (PFD) refers to equipment designed to help individuals stay afloat on the water's surface. This type of device is particularly useful for providing buoyancy and safety when divers are on the surface before or after a dive. While it can assist divers who might need extra support while ascending or descending, it is not commonly used during the actual diving phase because divers rely on their buoyancy control devices (like buoyancy compensators) to manage their buoyancy underwater.

Moreover, divers typically do not wear PFDs while submerged as they can restrict movement and might interfere with the diving equipment and activities. PFDs are beneficial for emergency situations or for safety measures when divers are waiting in the water, making this option relevant and accurate in the context of diving practices.
