Shane W I have a Atomic Z2X Reg and I am looking for a safe second... Which ones will work with my atomic first stage? Do you have any recommendations? I would like to stay inexpensive... Will the Mares MV and perstige work with my reg...?
ANDRES M It work very well. I'm a commercial diver and mares regs are working horses. Most important,low price!
B JANE G Most first stages are universal so it should fit. I have a ScubaPro and it works fine. I am unsure from your question if you are looking for a primary reg or just a backup octopus. This is unbalanced so I personnally wouldn't use it as a primary reg; it is strictly used as an octopus (backup) and will not breath as smooth as a balanced second stage at depth. However, as a backup it is great and you can't ever beat Mares quality.
If you are looking for a primary second stage I would always recommend a balanced reg. Yes they cost more but are worth the money.
DOYLE D The Mares Prestige is inexpensive and reliable. I have not have any issues with the reg. Connecting to your first stage should not be a problem. It ought to screw right in.
GARY H Any second stage will work with your first stage. The LP ports are the same threading and diameter regardless of manufacturer. It's how you can buy after market hoses such as miflex. The intermediate pressure from your first stage should also be a relative constant compared to other first stages. Hope this helps.
