Underwater communications for scuba divers

[Phillip T Mcdonald]

What company made the divers communications sets for voice to the bottom of sea the TV series

I don't know, but when I saw the title of this thread I was hoping it related to the general topic. When I got certified back in the mid-70's there was this whoopie cushion like bag thing that you inflated, and then spoke into underwater. You could hear the speaker's voice astonishingly well. I've never seen one since.

Nice typo. It was Voyage to the Bottom of the Sea, and ran 1964-1068 on TV, and was a 1961 movie.
Which are you referring to?

Added: there was no diver-to-diver wireless communication system in the early 60's.
It was a science-fiction show. Not everything in it was true.

THE CONSTANT PINGING IN THE BACKGROUND WAS CERTAINLY TRUE

Quite intriguing for a kid

Yep, reminds me of how, also back in the mid-70's, my buddy and I would sometimes take off a glove, exhale air into it (while rolled upside down) and then talk. The sound quality was surprisingly good with a little practice, though on the whole it was more of a novelty thing than a practical means of communication.

Yes, that sort of thing exactly. I'd think a very thin membrane, like a latex or nitrile glove, would work the best. I may try that next time we're in the water!

Best low-tech communications I've seen: Was on a dive with a couple that socialized with some hearing impaired folks. They used American Sign Language underwater.

Well, for awhile I was working on underwater communications, and had the idea of putting together a hard-wire system much like the intercom system we used in our U.S. Air Force helicopters. I figured that I could put a cylinder together with a battery, and the electronics for a wire to be between two buddy divers. Well, I did not have either the finances or the expertise to do this, and so dropped the idea.

But recently, I resurrected an old idea for underwater oral communications. That had to do with using the dive mask (an old, oval mask, U.S. Divers Company Champion Deluxe) to talk into as the diaphragm. I have a video of the technique that I’ll post below.
