Abstract
A second preproduction sample (NObs 74166) of an open circuit Scuba demand regulator is given a complete evaluation in accordance with applicable military and purchase specifications and the standard Experimental Diving Unit (EDU) evaluation procedure. The equipment evaluated consists of a two stage regulator, the D.A. Aqua-Master. This second preproduction sample is essentially the same as that in EDU Evaluation Report 8-59. In addition to substituting the old style upper cover and exhaust flapper valves, the manufacturer provided a new style molded rubber exhaust flapper. (Modified author abstract)
