There is a lot of information related to training and equipment that a S.C.U.B.A. diver should know. First of all, a diver needs to become certified. Divers in training take a class that covers the basics of diving. Then, they are tested on what they have learned. Secondly, there is a lot of equipment for diving. Some pieces of equipment include a buoyancy control device (BCD), regulator, dive computer, tank, and more. The equipment is pretty heavy. Finally, after a diver gets trained, she or he can go diving at incredible places. This ability opens up much more of the world to see. In conclusion, I think that is definitely worth your time, money and effort to get certified.
