Victor Armijo Campos of New York, a Mexican living in the USA patented an atmospheric diving suit with oil-filled rotary joints which were not pressure-compensated. The suit was reportedly taken to a depth of 600f/184m. Though clearly the suit could have reached 600 feet, it would have the dexterity of a brick. However, such devices were sometimes used quite successfully as observation chambers. The Campos joint is a fail-safe design. No pictures are found of the actual suit. A remarkable special feature is the possibility of adjusting the leg length by using an adjustable auger construction.
Therebreathersite was founded by Jan Willem Bech in 1999. After a diving career of many years, he decided to start technical diving in 1999. He immediately noticed that at that time there was almost no website that contained the history of closed breathing systems. The start for the website led to a huge collection that offered about 1,300 pages of information until 2019. In 2019, a fresh start was made with the website now freely available online for everyone. Therebreathersite is a source of information for divers, researchers, technicians and students. I hope you enjoy browsing the content!
