| If you've got an IP guage then couldn't you adjust the first stage to match the output required by the second stage? |

Two other things happen, first to get flow you need a pressure drop, second as the bottle pressure decreases the inter stage pressure increases. So the balance between the spring rate and the contact area of the LP seat and the drive pressure are critical in balancing the design. So changing the inter stage pressure is IMHO critical. My other point is when you try selling your two mixed brands on E-bay when your done and see just how much your rig is worth as a mixed set then. Just a thought. |

Most first stages aren't accurate enough on the IP that you'd be able to adjust them precisely between the 9 bar IP and 9.2 bar IP that one or the other needs, so trying to tweak one to match the other is a bit pointless, and you'll never feel the difference. If you put a Poseidon on an Apeks first stage or vice versa, then yes you will tell the difference, but not between Apeks, Scubapro, Mares, and just about every other normal reg on the market. Most of them are the same design and same technology, and a fair number come from the same factory anyhow. Digs. |
