Answer 1

A bc is a Buoyancy Compensator. It's a piece of equipment used to adjust whether the diver floats or sinks. Check out the Wikipedia article (my source) for more details.

Answer 2

BC stands for "buoyancy compensator".

It plays a few roles:

- keep the diver afloat when at the surface

- control buoyancy when underwater

- supports the air tank

it is actually an air bladder with a harness that is worn by divers. a hose connects the BC to the air tank so it can be inflated and deflated.

you will learn how to use it if you go for an open water diver course.
