NoDeCo bezels from the 1960's - Dive tables question

[Flying Doctor]

This pic should show you where I'm at.

The SUB 300 and 300T Metric bezels are the same. The 300T Imperial is US Navy. The 300 Imperial bezel is the 300 Metric numbers with meters to feet and a bit of rounding.

If the 300 had used the US Navy tables then the 300 Imperial would be the same as the 300T. It isn't, so that's why I am doubtful that the original 300 bezel was based on the US Navy tables.

Little bit more on the 1955 edition

The 1955 edition, published by Arthaud, of the original 1949 book by Tailliez, Cousteau, Alinat, Devilla, and Dumas, representing GROUPE D ETUDES ET DE RECHERCHES SOUS-MARIN (GERS). The first book published on diving with the Aqualung by the first military unit to be formed around the Aqualung. The text is French. The book is authored by Cousteau and the GERS team and presented by the French MARINE NATIONALE.

That's precisely the book I'm trying to find on my bookshelf. Sorry too say, as it's been years since I had any chance to put some order in that mess, I'll need some more time. Please don't laugh. Maintaining any semblance of order in a 2000+ collection of assorted books, isn't any kind of pic nick, believe you me ! Anyway, if I ever get my hands on it, I'll post a picture of the darn dive table.

Some news...

Couldn't find the 1955 edition of the book, I've read it for sure, but I fear it was a copy lent by someone. Sorry.

I've got the previous book : "La Plongée en Scaphandre", by P. Tailiez, F. Dumas, J-Y Cousteau, J. Alinat, Dr. F. Devilla, éditions Elzévir, Paris, 1949, printed 1st trimester 1950.

Page 61 "Les accidents de décompression" (Decompression accidents)
Paragraph "Table de plongée" (Dive table)
Quote : "Cette table en vigeur dans la marine américaine est extraite du Diving Manual 1943."
(roughly translated : this table in use in the American navy comes from the Diving Manual 1943)

Then a description of the table follows, how to use it and the table itself. Do you need a copy of the table ?

 

[Flying Doctor]

Yes please. That would be fantastic

Yes please. That would be fantastic

Ok, will do. Hope to find some time tomorrow. In the meanwhile, here's a link to a copy of the US Navy Diving Manual, 1943 edition. Dive table (in feet) is on page 170 of the book (that's is page 194 of the pdf). Thought it might help.

Thank you. Just been scanning through it. Man I love these old manuals

Knew you'd love it Love them too. Just one problem when you want physical copies : it's bulky and prices can be just plain silly

At last, the "Table de plongée du GRS" (and not GERS, which came later). Chapter 6 of the book already quoted, and as explained at the beginning of said chapter : "a metric version of the 1943 US Navy dive table". I've not enclosed the repetive dives part of the table, as I thought you were not interested in it. Hope it helped.

Oh wow, this is pretty cool. Thank you
