Double hose regulators

[Kunundrum]

aqualung did a new double hose a few years ago

here is a review from sport diver
Aqua Lung Debuts the Comeback of the Double Hose Regulator - Sportdiver.com

 

[DA Aquamaster]

If you are interested, I have:

1. An extra Pheonix Royal Aquamaster for sale (Pheonix nozzle, silcone diaphragm, new exhaust and mushroom valves and wagon wheels, new hoses, new voit style mouthpiece, custom PRAM label and very nice chrome) - $600

2. A Royal Aquamaster recent rebuild plus new hoses, new mushroom valves and wagon wheels, silicone diaphragm) - $400

I have a freind who was recently laid off and I'd like to turn at least on of these to money, then help her out with it by buying an item from her.

I have read about people using old double hose regs, but that was not my question. Why doesn't anyone make new ones?

Because there is no percieved market for them.

The companies, USD etc would have had to do some engineering work to add a LP and HP ports and they apparently did not know how, although Luis does, lol.

Scuba training changed radically in the 70s over the course of the decade from stringent NAUI/YMCA courses that lasted weeks to PadI one day wonders. In 1970 nobody used or knew to use an octopus and there were no BCs in use and by the end of the decade BCs were required, octos required, spgs required. In the 60s we did not largely use spgs, we used J valves.

Training standards changed to rely upon these new items and sharing air with an OOA diver via an octopus relegated Buddy Breathing to the dust bin of history.

Purge valves were integral to the way PadI teaches a regulator hand off. Double hose regs have no purge valve.

Double hose regs do breath very well but they are more positionally sensitive and require better technique which cannot be taught in today's one night scuba "lesson". (As does diving without a BC)

In the 70s the premier companies, Voit, USD, Nemrod, Sportsways, Healthways essentially disappeared, fell into disfavor or morphed into today's companies, et al.

USD > AL
Healthways > Scuba Pro
White Stag became Speedo and you guys will not wear their suits, lol
Voit, lol, they seem to make soccer balls in Mexico, dunno.

Scuba diving changed from a man's adventure sport to a family hobby. Local diving was de-emphasized and the scuba vacation industry was born with glitzy adds and exotic destinations ruined by hordes of Wall Mart shoppers in Scuba Steve outfits.

All of these things conspired to bring twin hose production to an end by about 1973 or so, debated, but Nemrod continued until I think 1998 and the US Navy has had AL make an amazing, modern, stunningly excellent training regulator for their use only recently called the Mentor. AL denies it. Only one of these is in civilian hands so they do exist.

AL did release a POC junker, poorly engineered, ugly as sin, double hose a few years ago called the Mistral. Most of us were not impressed with it and it died.

Does this answer your question?

And here I am talking about diving in Maine... I hate you. :mooner:


I am dying to get back to Bonaire (and yes, I only dove a double hose in Bonaire).

Take heart Luis, this is partly a recon mission...and I have a shop would love to have us down with no restrictions....SD-XII maybe?????.....although he did threaten to drag out an old B&W camera to film us.

Can you rig up one of the old double hose regs with an inflator for a modern BC?

Can you rig up one of the old double hose regs with an inflator for a modern BC?

With the exception of using the hooka port on DA Aquamasters, Royal AMs and the Voit equilivents, pretty much none of the old DH regs had LP ports. And because of the design of most modern BC's they do now work well with DH regs. DH regs require the cans to be placed much lower than is possible on most modern BCs. The BP/wing varity of BC will usually accomidate the position requirements of a DH reg. I currently use a Zeagle Express Tech for that vary reason plus is is very easy to remove the bladder and dive it bladderless which is what most of us who dive DH regs prefer to do anyway. My bladder came off day 2 here on Bonaire and will remain off the rest of the trip...there is no need for it

Yes, that is what we have been trying to tell you but there is a sub forum here for vintage plus Vintage Double Hose.

Good luck.

Can you rig up one of the old double hose regs with an inflator for a modern BC?

......yes, as mentioned, if you have one with a hooka port, it is possible....a few years a ago I bought a couple 'new' LP hoses from Vintage Scuba Supply (Oregon USA) that were custom made where one end attaches to the hooka port and the other end has a conventional/modern attachment so it fits a moden BC. ...back in the day when I bought them, they were the very last 2 such hoses he had and said once those were gone, they were gone forever....however, that was a while back and maybe more have been produced since then ? ...anyway, those 2 hoses are still new-in-box, but I'm hanging on to them if I ever decide to play with some of my twinhoses.

The easiest way to hook up LP accessories to a DA aquamaster or RAM is to get a hookah port adapter from vintage double hose, which gives you one LP port, than get a three-way LP swivel adapter from Trident. It works great; one port points up and to the left, which routs the LP inflator well, another down and to the right which is nice for an alternate 2nd stage under the right arm.

Of course the phoenix solves this problem as well as the HP port issue, which is otherwise usually solved through a banjo fitting. Lots of vintage divers choose to dive without HP and LP accessories anyways, but realistically I think we can agree that in most cases having an SPG and an alternate 2nd is overall a good thing.

Or, you could build one of these........a MB Mk3 mounted on a DA or RAM......This is useable with a Conshelf XIV DIN adapter...........or standard yoke.....
