A diving chamber is a vessel for human occupation, which may have an entrance that can be sealed to hold an internal pressure significantly higher than ambient pressure, a pressurised gas system to control the internal pressure, and a supply of breathing gas for the occupants. [1] There are two main functions for diving chambers:
The first diving competition was held in 1885, in Germany. [2] In the first Olympic diving competition in 1904, American George Sheldon won gold in platform diving.

A deck decompression chamber (DDC), or double-lock chamber is a two compartment pressure vessel for human occupation which has sufficient space in the main chamber for two or more occupants, and a forechamber which can allow a person to be pressurised or decompressed while the main chamber remains under constant pressure.
Today, in Latin America, diving by professionals from heights of 100 feet (30 m) or more is a common occurrence. [5] Cliff diving has been documented as far back as 1770 when Kahekili II, king of Maui, engaged in a practice called "lele kawa", which in English means jumping feet first into water from great heights without making a splash.
