DivAir

Dedicated to the discussion of vintage diving methods and equipment available prior to 1970. This forum section is limited to the diving without modern BCDs or use of an Octopus.

Forum rules
“Note: If you are new and have a question, please start by using the search function. You will probably find that your question has been answered. A lot of vintage subject has been discussed many times, there is very little new in vintage.”

When this forum section was first discussed, a possible name was Cranky Old Guys. That name came from the belief that those divers who feel that a more classic section of vintage diving was needed on VDH and are most likely cranky old guys. But it is also those individuals who actually lived the chosen time period and used the equipment of that era. Those people might also be the ones who grew up with Sea Hunt and Mike Nelson.

The forum will be moderated by Captain and Simonbeans, both vintage in many respects. However these two divers started when J-valves and depth gauges were common and a computer was a distant vision yet to be developed.

DivAir

Well, Portage has come and gone. I put some significant time on my DivAir model B at Portage. Considering it's place in the time line of evolution I was really impressed with it's performance. Jerry's diaphragms really brought that reg back to life! I got home from work early today and Lake Michigan was flat and inviting. There is a catch of course. It was flat because there was a West wind which pushes the warm surface water out and brings in the cold deep water. That means dry suit diving. So, I rigged my Poseidon Xstreams to the left post on my double set with the iso manifold and the DivAir to the right and went out to dive the local wreck. The DivAir needed a good rinse anyway right?
So, I drafted my son for my top man and went out to the SS Niagara, a side wheel steamer that burn't to the waterline in 1856 and sank in 50 feet of water. I splashed in and dove the wreck breathing off the DivAir and using the Xstreams for my dry suit and wing. Yes, I can see Allan cringing a thousand miles distant. But in 50 degree water I sure like my dry suit. Ha. Anyway the DivAir performed very well during the 35 minute dive. I would have gone longer but I told my son I'd be up in 30. Damn shame I had 1200 left in the double set.
So anyway, my DivAir seems to be performing quite well and I'm really happy with it. Those who also dived their DivAirs at Portage, what are your thoughts. Just curious. Once again, it was good to see everyone at the meet. It was really good to de stress and just go diving for a couple days. Nothing better then a swim suit and a DH outfit with no freakin weights, yeah!

Jim,

I now have a little over 6 hours on my Divair Model E. In my opinion, it compares to a DA in performance. With that said, I have taken it to around 70ffw and didn't notice any difference from those dives in shallower water.

It continues to surprise me that the exhaust hose remains clear of water while swimming in the normal position. If I roll to my left, I can hear water "gurgling" into the hose. Still, a gentle puff purges the hose clear.

It is also one of the more "attractive" designs to my eyes. While I own a fiberglass version, I find the Model B aluminum version to be the best looking of the three variations.

The five that I have serviced would never have been done without your assistance. Thanks, again!

I think the DIVAIR breathes better than a BROXTON.....maybe, but it aint no MISTRAL or DA AQUAMASTER IMO. Still, it cool to dive one and even cooler that we had 4 in the water at one time at PORTAGE. I would never sell mine, but I have one extra that Greg rebuilt available for sale if anyone is as adventurous as us 4 are. I look forward to seeing the pics of all 4 of us by the silo???? Anyone????

I took the picture with Karls Camera. three different pics of all 4 but the 3rd I think was the best.

Though are efforts are mainly channeled towards the resurection and enhancement of US Divers and Voit regulators it is truly inspiring to see those efforts, and the knowlege gained from them, result in the restoration of more exotic and rare regs such as the DIVAIR and others. Well Done. Now all we need is some Northrill's resurected and assembled at portage.

Because of the wide view mask, I think this photo was taken sometime after 1960, most likely 1961 or 62. Where did you find this photo? Maybe an early book or magazine? Nice find.
