Hannes Keller's 820 ft dive was on Nov 4, 1960. The story is in the Feb. 1961 issue of Skin Diver magazine page 22. The dive to 1,000 ft where two divers died was on Dec. 3, 1962. The story is in the Feb. 1963 issue of Skin Diver magazine page 8. The story of Hannes Keller's dives should also be on the internet somewhere.

Actually..i am pretty certain that i didnt offer an opinion. I think it was a question...I have heard that many of them breathe hard at depth from people that used to dive them in the 60's and 70's...Keep in mind ..i am not looking to bash vintage equipment..i have previously had desire to purchase and dive with some...

I don't see it.
It's not listed in the Keller history. 728 is listed.

Hannes Keller's Bio on a site he owns as a publisher. List 722 and 1000

Skin Diver magazine Feb 1961. On Nov 4, 1960 at the Toulon Naval Base in France, Hannes Keller using the new U.S.Divers Calypso Regulator submerged to a simulated depth of 820 feet in a water filled high pressure chamber. Diving depth was reached in 10 minutes, decompression took only 49 minutes. This must be out on the internet somewhere, everything else is.

"modern dive equipment is made more complicated" The more complicated, the higher the risk in usage. Remember the Space shuttle has 250,000 moving parts, all made by the lowest bidder and it has to work.

Simple viontage gear such as the DA Aquamaster and the Royal Aquamaster are rock solid and bullet proof. New parts are available whichg makes them diveable. I have had both on wrecks at 120 and 135 resopectuively, the DA Aquamaster was silky smooth. The ram was of course better on the deeper dive. The upside is when doing photography the bubbles are behind you. With the redesign of the HP nozzle of the Royal Aquamaster, the new design allows for 3 HP ports, 3 LP ports and in my opinion breathes at least 50 better than the older Royal Aquamaster when it is tuned to perfection.

Compared to my 800 dollar plastic single hose, whuich is a great breather shallow or depth, it still sucks compared to the new Pheonix double hose regs performance which inhale breaks at .75 inch of water on the magnahalic. Complicated no.. they dont have to be. Simple and robust yes
