Deep diving in the ocean is done very carefully in special suits and helmets. Pressure under the ocean is significant and can be immense by the time you are down a few hundred feet. Scuba diving is sometimes used commercially, but only to depths of about 120 feet. - Many large dockyards and navies employ 'clearance divers ' to repair items on the bottom of ships and work on the dockyard floor. These divers wear heavy canvas suits and large hard helmets, fed air by lines from the surface. They can work down to 300 feet deep or so. Research and oilfield divers can wear special hard suits that allow them to go down almost 1,000 ft. These divers often wear "Newt suits" made by the Canadian company Nuytco Research in Vancouver.
The rigid diving suit is pressurized to offset depth pressure and it needs rigidity to prevent it from expanding, allowing the person to swim easily.
