Each year an estimated 500,000 new scuba divers are certified in the U.S. These people dive for different reasons. For some, the opportunity to enjoy a contrast to their everyday life is sufficient attraction. The undersea world is quiet, it allows movement in three dimensions and it supports a totally different range of plants and animals. Other divers may find the search for evidence from earlier generations fascinating.

For some, diving will become more than just a hobby. Some people make it their career by studying the cycle of life in the sea while others will play a role in extracting the energy and mineral resources which lie below the sea bed. Covering 71% of the earth's surface area and containing 98+% of the water, the oceans offer a huge resource for both the hobbyist and the career minded individual. Despite its dominance, the ocean floor is largely unexplored and unmapped.

Practically everybody can enjoy diving, although certain physical demands are required. Diving offers a fascinating challenge, in return it asks you to respect the sea. With proper training and the appropriate level of fitness you will be able to dive with confidence.
