ZPG-3W was not a name or an identification number, but a class of aircraft. Four of these, the last and largest of the Navy's airborne radar picket blimps, were built in the late 1950s. The rotating radar aerial was contained inside the gas envelope. They were among the largest non-rigid airships ever constructed. The entire program was discontinued in 1961. Today this mission is performed by fixed-wing aircraft.

The gondola and other hard parts were probably salvaged for an investigation into the cause of the crash. I doubt there is anything left in the water.

Regulators - Second Stages

regulator

There are a variety of choices you can make here, mainly concerning adjustability. High-end second stages come with one, two, or even three adjustments. Some are actually useful, others are pure marketing nonsense. With thick gloves on, you may not even be able to work them in the water. All user-accessible adjustments have a much narrower range of operation than the internal adjustments that a technician can make. My experience is that if a reg is malfunctioning, the user adjustments will be useless to stop it. On the other hand, if you're a gadget person who likes to fiddle with things, some of the adjustments actually can make a noticeable ( although not essential ) difference in breathing. On the theory that extra moving parts are extra failure points, I would avoid adjustable regulators, but that's not really possible anymore. With most manufacturers, the non-adjustable regs are the bottom of the line, and you don't want that, so buy a good reg, and if it has a few useless bells and whistles, live with them.
