A DA Aqua Master will likely be the cheapest route. Either the Cyclone or Phoenix first stage update and the HPR 2nd stage with necessary accessories and you will have a double hose that breathes better than any before it. Only the Argonaut Kraken will out perform it.ScubaLawyer wrote:Agree with Bryan. As I recall the DA Navy has Broxton internals which means no venturi assist. I just finished rebuilding a Voit Mariner with the same internals. It breathes but takes some sustained effort. It was a fun project and I learned a lot but it was a pain in the butt overall. I believe a Phoenix or Cyclone 1st stage will fit the DA Navy but not a HPR. For a first go at rebuilding a DH two stage I'd go with a Aquamaster or Voit Navy (same thing internally) and much better breather. My 2psi. Mark
It seems like we all (myself included) have the urge to make things work better than they did when new, but if you just put it together in as close as possible to original configuration (with new or resurfaced parts like hp seat and new lp seat), and tune it as well as possible, you can experience the feel of what diving was really like in the 50's and 60's. We were just glad to be able to breathe underwater even if it took a little effort and imposed limitations on depth and exertion levels. You may find it interesting.... that's one of the aspects of Vintage Diving that you might like to experience at least once. You can always add performance enhancement features to it or another regulator at a future date. That's fun too!
Well said Bill.......With all the updates we have made for the double hose in the past decade or so I think it's important that we remember how challenging the original "Lungs" could be and diving with one is an experience that I hope all double hosers get to have.antique diver wrote: ↑Tue Apr 03, 2018 12:29 amIt seems like we all (myself included) have the urge to make things work better than they did when new, but if you just put it together in as close as possible to original configuration (with new or resurfaced parts like hp seat and new lp seat), and tune it as well as possible, you can experience the feel of what diving was really like in the 50's and 60's.
