Salvage diving is a specialized form of diving that involves the recovery of valuable items or materials from a sunken ship, plane, or other underwater wreckage. Salvage divers may be employed by salvage companies, government agencies, or insurance companies to recover lost cargo, equipment, or other items of value. The work can be physically demanding and potentially dangerous, as divers may have to contend with poor visibility, strong currents, and other hazards while working underwater. However, salvage divers play a crucial role in recovering valuable assets and preserving the marine environment.
