It will essentially compress the tanks/rebreather unit on the divers back, the hoses, the mouthpiece, and even the dive mask into a single, self-contained unit. That would seem it is intended as an oxygen rebreather, which is a subset of rebreathers intended for extended, but very shallow dives, typically only up to 15 feet, as the pure O2 used in the system becomes toxic beyond this depth.

Thanks for the memories. they might consume up to 6,000 calories each day (more than double the recommended intake) to keep up with their demanding shifts in the water. The amount of breathing gas required for an O2 rebreather is based on biological requirements. Before taking up residence in the saturation chamber, the core living space of the system, every diver must pass a medical workup including, among other things, a hunt for any signs of infection. Inside that divers body, it would be as if millions of tiny explosives began to detonate. And this brings us back to those final family phone calls. Like all diving equipment, the Diving Helmet prolongs the underwater breath to 1 minute and 33.33 seconds or, while holding the Breathing Reed, to 3 minutes and 6.67 seconds. ), and, specifically, the oil and gas industry, needs commercial divers like Hovey who can go to the seabed to perform the delicate maneuvers required to put together, maintain, and disassemble offshore wells, rigs, and pipelines, everything from flipping flow valves, to tightening bolts with hydraulic jacks, to working in tight confines around a blowout preventer.
