History of Balanced Regulators?

[Natanlapl]

Hi, I am looking into the development of SCUBA regulator innovations and their history. Does anybody know the first brand or reg to offer or evolve to a balanced system? Otherwise some examples of older balanced regulators would be cool.
Thank you.

Single or double hose? If single, first or second stage?

Well all would be interesting, but specifically single hose first stage, unless 2nd stage balancing came first?

I have read that US Divers Royal master 1964 was first balanced double hose?

Like most things in diving, balanced regulator designs were used in industry for a long time before being applied to the diving market — mostly in laboratory and precision control applications.

Is there a recognizable introduction of the technology to scuba? I will have a research into pre scuba too thank you.

Aqualung Calypso in 1961.

It gets a little confusing with the Calypso because Aqualung later used that name on a first and second stage combo that had an unbalanced piston first stage.

The Calypso was used by Hannes Keller to set several depth records in the early '60s, included his ill-fated (for another diver) 1000' dive.

@Akimbo posted this a few years ago:

If you want to know more about the regulator, @John C. Ratliff has and has dived this reg and a version that was sold under the Voit name.

If you want to know more about Hannes Keller, you could start with this very interesting thread: Hannes Keller's 1,000' Dive . Diving legend and scubaboard regular @Sam Miller III was actually there!

@Luis H will know the definitive answer to the "first balanced regulator" question.

HISTORY OF THE SINGLE HOSE REGULATOR | BluTimeScubaHistory - 1958 Poseidon Cyklon balanced

I have found this site stating that Poseidon's popularity in 1958 was partly based on its balanced first stage design, can anyone dispute/ shed light on why calypso is still considered first?

Just found this thread. What poseidon cyklon model is this?

The Poseidon Junior and early Cyklons were an unbalanced diaphragm design.
