There are a number of important facts about scuba diving that you need to know. The first one is that you need to have a self-contained underwater breathing apparatus. These high pressure tanks that are strapped to the back of the diver, provide air to the diver that is regulated through a breathing device. This lets the diver go very deep in the water without worrying about coming up for oxygen.
