Professional Diving is a type of Diving where the diver is paid for their work. There are several branches of professional diving, the most well known of which is probably commercial diving. Any person wishing to become a professional diver normally requires specific training that satisfies Legislation , such as that set by the United Kingdom Health And Safety Executive . Due to the dangerous nature of some professional diving disciplines, specialized equipment such as a diver to surface communication system is often required by law. ] EQUIPMENT Diving suit See Also: Diving suit Depending on the water temperature and length of dive, the diver will either use a Wetsuit , where Neoprene provides thermal insulation but the diver gets wet, a hot water diving suit which is similar to a wetsuit but is flooded with warm water from the surface through an umbilical, or a Drysuit , which keeps the diver totally dry and relies on either the suit material or the air trapped in thermal undergarments to insulate the diver. Certain applications require a specific type of dive suit; long dives into deep, cold water normally require a hot water suit, whilst diving into potentially contaminated environments requires a drysuit. US Environmental Protection Agency Guidance For Contaminated Environment Diving Breathing apparatus A number of factors dictate the type of breathing apparatus used by the diver. Typical considerations include the length of the dive, water contamination, space constraints and vehicle access for support vehicles. Some disciplines will very rarely use Surface Supplied Diving , such as military clearance divers, whilst commercial divers will rarely use SCUBA Equipment . Scuba See Also: Scuba diving SCUBA equipment is normally used by media and military divers, often utilizing specialized equipment such as Rebreather s, which are closed circuit SCUBA equipment that recycles breathing gas instead of releasing it into the water. It is the "re-breathing" of gas that makes rebreathers ideal for long duration dives, efficient decompression when the gas mix is adjustable, and for the observation of animals in the wild due to the lack of noisy bubbles. These characteristics also make rebreathers ideal for military use, such as when military divers are engaged in covert action or when performing mine clearance where bubbles could potentially set off an explosion. Open Circuit Scuba equipment is occasionally used by commercial divers working on sites where surface supplied equipment is unsuitable, such as around raised structures like a Water Tower , or in remote locations where it is necessary to carry equipment to the dive site. Normally, for comfort and for practicality, a Full Face Mask such as those manufactured by Kirby Morgan will be used to allow torches and video cameras to be mounted onto the mask. The benefit of full-face masks is that they can normally be used with surface supplied equipment as well, removing the need for the diver or the company to have two sets of expensive equipment.
