UMEL 1969 (UK)

In 1969, Underwater and Marine Equipment Ltd. located and restored the old Peress suit, known as the JIM 1 (named after its first operator, Jim Jarrett), and re-engineered the suit and joints. The new joint, named Type 2, was a fail-safe design. UMEL successfully dived JIM2 to 400f/123m in 1972 and later built twelve suits. By 1974, UMEL had patented a Type 3 joint which was eventually retrofit to previous JIM suits. In 1975, the rights to the JIM suits were purchased by Oceaneering International Inc. In 1976, a JIM suit made a series of historic dives to 905f/278m under 16 feet of ice cover for PanArtic Oil in the Canadian high arctic.
