The profession of commercial diving is very different from the sport of recreational diving. Although commercial divers may enjoy their jobs, they dive for pay rather than for fun. Commercial divers engage in a variety of activities. Some work offshore, constructing and maintaining underwater oil rigs and pipelines. Others specialize in inland and inshore diving, where they work on bridge, harbor, and similar civil engineering projects. Still others are members of the military. Military divers engage in both combat and non-combat functions, including ship maintenance and repair, mine clearing, salvage, and covert operations. Commercial divers use different equipment than that typically used by recreational divers. Most commercial diving operations require the use of full-face diving masks or diving helmets. Unlike recreational scuba rigs, these incorporate surface-supplied breathing gas and voice communication capabilities. The most specialized protective equipment is required by divers who perform the dangerous job of inspecting and repairing sewers.
