170123-N-TI693-051 NAVAL SUPPORT ACTIVITY PANAMA CITY Fla. (Jan. 23, 2017) Navy Diver 2nd Class Kent Knudson, a command diver at the Navy Experimental Diving Unit (NEDU), carries wrenches through the Ocean Simulation Facility. Knudson will be one of six Sailors compressed to a depth of 500 feet for the first saturation dive in 10 years. The dive will accomplish two goals: the first is to evaluate, test, and certify the new HeliCom Matrix which is a system that returns speech patterns to normal after the breathing of helium to enable better communication after breathing mixed gasses, and the second will be a training scenario to maintain qualifications for saturation diving.
