DESCO Browne Commercial Diving Helmet – Lightweight For decades, DESCO has been providing the most superior diving helmets and equipment. The DESCO 29400 Commercial Diving Helmet is no exception. The Browne Commercial Diving Helmet is designed to keep you safe and secure during even the most extensive deep sea diving excursions. The DESCO "Lightweight" series of helmets are of the same high quality materials and constructions as their heavier brothers. They have considerably less weight and volume than the "heavies". All these diving helmets share the Lightweight (Sponge) pattern breastplate and top shell, with modifications to suit varying customer and market demands. The Superior Commercial Diving Helmet Divers Trust The Browne Commercial Diving Helmet is similar in design to the Japanese and Bob Kirby deep sea diving helmets favored by many commercial divers. Its standard features include oversized windows sealed with O-rings, an integrated air control valve, a large air diffuser/muffler, a low profile air/communications block, and a double exhaust valve. The air inlet can be adapted to a variety of hose fittings including 1 1/16"-17, 9/16"-18 Oxygen, and JIC. The commercial diving helmet is fitted with a four wire Marsh Marine type plug set up for two wire operation, but can be adapted in the field for four wire operation with the addition of a microphone. Browne Commercial Diving Helmet Constructed with Proven Design The exhaust of the Browne Commercial Diving Helmet uses the proven U.S. Navy Mark V valve as the primary stage and a rubber flapper valve secondary stage.
