Diamonds are a man's best friend in this reality series, which follows an intrepid marine mining crew of rugged divers and sailors from Washington state who head to South Africa in search of buried diamonds under the sea. Led by Captain John Aydelotte, a motorcycle-riding former chief engineer at Boeing, the men battle the dangerous Skeleton Coast waters, filled with sharks and surrounded by unpredictable weather, and risk their lives in search of an untouched jackpot of diamonds hidden deep in the ocean floor. The other crew members include John's son, Jason, who inherited his dad's hot-headed temper; ex-Marine J.R., the master mechanic; expert divers Marty and Sam; and former Navy medic Doc, who at 59 is the oldest -- and also wildest -- of the group.

Diamond Divers - Surface-supplied diving - Netflix
Surface-supplied diving is diving using equipment supplied with breathing gas using a diver's umbilical from the surface, either from the shore or from a diving support vessel, sometimes indirectly via a diving bell. This is different from scuba diving, where the diver's breathing equipment is completely self-contained and there is no link to the surface. The primary advantages of conventional surface supplied diving are lower risk of drowning and considerably larger breathing gas supply than scuba, allowing longer working periods and safer decompression. The copper helmeted free-flow standard diving dress is the version which made commercial diving a viable occupation, and although still used in some regions, this heavy equipment has been superseded by lighter free-flow helmets, and to a large extent, lightweight demand helmets, band masks and full-face diving masks. Breathing gases used include air, heliox, nitrox and trimix. Saturation diving is a mode of surface supplied diving in which the divers live under pressure in a saturation system or underwater habitat and are decompressed only at the end of a tour of duty. Airline, or hookah diving, and “compressor diving” are lower technology variants also using a breathing air supply from the surface.
Diamond Divers - Band mask - Netflix
A band mask is a heavy duty full-face mask with many of the characteristics of a lightweight demand helmet. In structure it is the front section of a lightweight helmet from above the faceplate to below the demand valve and exhaust ports, including the bailout block and communications connections on the sides. This rigid frame is attached to a neoprene hood by a metal clamping band, hence the name. It is provided with a padded sealing surface around the frame edge which is held firmly against the diver's face by a rubber “spider”, a multiple strap arrangement with a pad behind the diver's head, and usually five straps which hook onto pins on the band. The straps have several holes so the tension can be adjusted to get a comfortable seal. A band mask is heavier than other full face masks, but lighter than a helmet, and can be donned more quickly than a helmet. They are often used by the standby diver for this reason.
