JIM Suit - U.S. Naval Undersea Museum
JIM Suit of the U.S. Naval Undersea Museum
Treasure hunters developed early atmospheric diving suits (ADS) to dive on shipwrecks. Commercial diving and oil drilling industries resurrected ADS in the 1960s. The JIM suit, named for test diver Jim Jarrett, was the first modern-day commercial ADS. It weighed 910 pounds and operated to 1,500 feet. The Navy began using ADS after testing the JIM suit in 1975. Today an atmospheric diving suit, the ADS 2000, is the first component of the Navy’s submarine rescue system.
