Diving

The beauty of the diving, tranquility, and enjoyment make it possible for me to return to the water every summer. In a deep place underwater, I can calm my soul and enjoy a wonderful scene that can only be seen under turbulence. About two years ago, as a key to the southern end of Florida, we just got on a typical diving boat, this is my first diving. My father and I have planned this trip for a couple of months, and today is the day it happens. When the sound of the motor began to suffocate in my ear, the scent of gasoline penetrated my nostrils and imagined where we will arrive in an hour.

Recreation diving (sometimes called sports diving or underwater diving) is a popular leisure activity. Technical diving is recreational diving especially under harsh conditions. Professional diving (commercial diving, for research purposes, or diving for economic benefits) involves working underwater. Public safety diving is underwater work done by law enforcement agencies, fire rescue, underwater search, rescue and recovery diving team. Military diving includes combat diving, clear diving, ship propagation. Deep sea diving is usually underwater diving using equipment that is equipped on the surface, and usually uses standard dive clothes and traditional copper helmets. Hard hat diving is a diving using helmets such as standard copper helmets, other free-flowing and lightweight demand helmets.

Diving can be done for various reasons both personally and professionally. Leisure diving is for enjoying completely and there are many technical fields to boost the interest in the water such as cave diving, rec diving, ice diving, deep diving, etc. Underwater tourism is mainly done by scuba diving and the relevant tour guide must follow it. In the recreation diving community, divers are working both full-time and part-time as lecturer, assistant coach, diving master, diving guide. In some jurisdictions, professionalism, especially customer's health and safety responsibilities, leisure diver's guidance, diving leader award, and diving instruction are recognized and regulated by domestic law.

In military and commercial diving, bounce diving usually means every unsaturated diving. Multiple bounce diving with different depth and duration is usually done in one day, repeated pressure reduction is necessary. Bounce and saturated diving are both types of stressful diving. One of the advantages of saturating diving is that you only need to perform decompression in the pressurization chamber instead of multiple depressions (bounce diving) that are required when the diver uses multiple short dives. Decompression is a very long process that can last several days or weeks after a depth of over 200 feet, so a single decompression can save a lot of time and is therefore more efficient. In addition, saturated diving reduces the overall risk of project DCS, since there is only one gentle decompression rather than multiple short decompressions.
